Tech startup: I really do make mobile phones!

Chapter 164 The Debate Over the Gyroscope's Route
In the E3 Technology Innovation Exhibition Area, crowds surged amidst a torrent of sound, light, and electricity.

The exhibitors here are more diverse. Chen Mo, Zhao Tiezhu and Gong Yun strolled among them, their eyes scanning the various dazzling VR glasses, intelligent robots and futuristic 3D displays.

Zhao Tiezhu marveled at all the novelties, while Gong Yun quietly followed behind the two, holding the cat carrier containing her beloved cat, Xiaomi, with a calm gaze.

Suddenly, Chen Mo's footsteps stopped in front of an inconspicuous booth belonging to a domestic exhibitor.

His gaze was fixed on the several milk samples displayed in the center of the booth—those familiar brick-shaped packages!
"Le Li Zhen?" Chen Mo's voice trembled with disbelief, and he almost instinctively walked over quickly.

"Hey? Brother Chen, wait a minute!" Zhao Tiezhu was being attracted by a neon dancing robot next to him, and seeing this, he quickly called Sister Gong to follow: "Brother Chen, what's so interesting about a milk carton?"

Inside the booth, a technician wearing a T-shirt with the "Quanling Packaging Materials" logo smiled knowingly when he saw Chen Mo's focused and even somewhat excited expression, especially the slight tremor in his fingers as he gently touched the surface of the packaging material.

"Dude! You're studying materials science too, right?"

Chen Mo took a deep breath, nodded, and stared intently at the packaging: "Congratulations! Congratulations! You've finally created our own 'Leli Pillow'!" His tone was full of heartfelt satisfaction and excitement.

Ruidian Lile Company monopolized the "Leli Pillow" packaging technology, and has long occupied 75% of the profits of China Dairy Company since the 70s. It is also deeply tied to the development of Yili and Mengniu, and is known as the "Dairy Arms Dealer".

Packaging costs account for a very large proportion of a dairy company's total costs (for example, of a carton of milk costing 3.5 yuan, 2.4 yuan is subject to "Lile tax"!).

The "Lile Tax" is not as well-known as the "Pingguo Tax," but it has actually been in effect since 1970, causing pain to many people who grow flower materials!

The "Lile Tax" wipes out 75% of the profits of the domestic dairy industry, leaving dairy companies with only about 5% profit margin year after year.

When there are no profits and even losses, some dairy companies will look for ways to make a profit.

Now you know why our dairy industry is so bad, and how Ouzhou achieved its high welfare standards!

Even though the continuous decline in domestic raw milk prices has led to increased losses for dairy companies, Lile's profit-sharing model has never been affected.

The technician's pride grew even stronger. He picked up a sample box and corrected, "Thank you! However, this isn't a Tetra Pak pillow; it's our independently developed 'Quanling Bag'!"

"Through the efforts of Quanling, we have finally broken Lile's decades-long monopoly in the domestic market!"

He paused, then raised his voice a few decibels, with a sense of triumphant satisfaction.

"Currently, the only companies in the world capable of producing this six-layer composite aseptic liquid packaging material, besides Tetre Pak from Ruidian, SIG Combiblac from Malaysia, and Quanling from our own flower company!"

The tech guy pointed to the logos of the partner companies on the display board: "See that? Mengniu, Yili, Queshao. Domestic and international giants have all started using our products!"

"In the future, the total cost of domestic dairy companies can be conservatively reduced by 20%-40%. They will no longer be held by the throat by Lile's tax collection and will finally have the confidence to say 'no'!"

Peng and You may have fought, but let's give each other some space!
Chen Mo clapped vigorously, his eyes even getting a little hot: "Well done! As a materials scientist, I have to give you a thumbs up. This is a wonderful comeback for us materials scientists!"

Even after leaving the Quanling booth, Zhao Tiezhu was still completely bewildered.

"Brother Chen, it's just a milk carton! Why are you getting so worked up? Your hands are shaking!"

Gong Yun raised her eyebrows slightly and cast a curious glance, clearly equally puzzled.

Chen Mo calmed himself down and looked at Zhao Tiezhu with a deep gaze: "Tiezhu! Materials science is the mother of industry, the foundation of all manufacturing!"

"It's like cooking; first you need rice to cook! I'm excited because I see that our country has managed to overcome a major obstacle and catch up in the most basic and vulnerable field of materials!"

After that, he seemed to be lost in memories.

"You know the four major pitfalls of biology, chemistry, environmental science, and materials science, right? When I chose materials science, I really had to thank my high school chemistry teacher, an old man who would slam his fist on the table and curse and go off-topic whenever he mentioned 'Leli Pillow'."

"It was his unwillingness to give up that made me feel that working on materials, especially breaking the foreign monopoly on these exorbitantly priced materials, was even more meaningful!"

Chen Mo sighed, his tone heavy.

"However, researching materials is extremely difficult. It requires huge investment, a long cycle, and failure is the norm. Success is accidental. Resources, luck, and perseverance are all indispensable, and it often requires the silent efforts of several generations!"

Taking the J-20's stealth paint and carrier-based interceptor cables as examples, they were definitely not discovered through some kind of massive industrial investigation as some marketing accounts claim.

The progress you see is the result of generations of breakthroughs by materials scientists, and it belongs to the core materials that "cannot be obtained, bought, or begged for".

For example, the development of stealth paint materials in four generations: from iron oxide-based materials in the 80s, to crystal and fiber composite materials in the 00s, to composite materials in 10, and then to classified materials in 15.

Starting in 10, some materials used in stealth coatings, such as the core filler for broadband absorbing coatings and silicon carbide fiber reinforced composite materials, were classified as Class A controlled substances by the state.

The stringency of Class A controlled materials is roughly equivalent to that of nuclear materials. Marketing accounts claim that the fourth-generation stealth technology developed in 15 was produced by an unknown small paint factory. Isn't that ridiculous?

As for the aircraft carrier interceptor cable, that's just a rumor.

I designed a phone that scored 85 points, but I still couldn't catch up with North America. I could only get a factory with a score of 60 points to manufacture it. Then I sent people to spend four months improving the factory's quality to 85 points. That's how it is!

As for North America, I could originally make a phone that scores 85 points, but I advertised it as 100 points. I saw that there was a contract manufacturer on the other side that could make a phone that scores 60 points. The cost of making it locally would be 200 million US dollars, but on the other side it would only cost 20 US dollars, so I bought it and used it as a substitute.

So, when it comes to materials, either you get incredibly lucky and create a completely new material, or you accumulate experience little by little through trial and error, just like normal materials research.

The first generation found a passable material with a score of 60 through trial and error; the second generation found an optimized material with a score of 85; and the third generation found a perfect material with a score of 90.
"So! Materials science is not something that can be done by chance; it requires a lot of accumulation!" Chen Mo said earnestly.

"Brother Chen, aren't you being too modest? I feel like you treat data processing like it's nothing!"

Upon hearing this, Zhao Tiezhu chuckled and started counting on his fingers.

"Look, the gaseous lithium electrode, the mysterious paint on the gyroscope, the polymer materials used in the micro-motor—they're all done! I think it's pretty easy!"

Chen Mo was amused by him and shook his head helplessly: "I was just lucky and stumbled upon a few key points."

"True breakthroughs in materials are built upon countless experimental failures and tedious data accumulation."

"Alright!" He decisively changed the subject: "We've seen the booths of Chengbao Yuancheng, but what about Chengke Micro Motor? Are Factory Director Feng and Xiao Zhou still holding their ground?"

Zhao Tiezhu quickly pulled out the crumpled "Exhibitor Guide" that he had kicked into his pocket, and traced his fingers across the booth map.

"W1 Industrial Automation Hall. Found it! Booth number 20!"

He clapped the guidebook in his palm.

"Hey, it turns out it's at the very back. We were so drawn in by the laser engraving of the German-made barrels, the bartending robot arm of the neon-colored Fanaco, and the industrial machine tool of Kyoto University that we didn't even look back!"

Chen Mo thought about it and realized that was indeed the case.

The cool and stylish application products attracted most of the visitors, while individual industrial parts, even with their specifications marked, were incomprehensible to tourists.

"Let's go check on Director Feng and Xiao Zhou. Chengke only brought some parts to showcase this time, nothing special, so they'll probably be deserted. Let's go and give them a boost, since they still have to endure being sidelined for a couple more days!"

"That's great!" Zhao Tiezhu's eyes lit up. "I'll go ask Xiao Zhou and Director Feng if we can increase the power of that miniature motor and enlarge its size as well."

Chen Mo gave him a playful kick, annoyed: "You brat! Are you never going to stop? How many times have I told you, Orange Technology's main business is making mobile phones! Smartphones! We don't make cars! We don't make cars!"

Gong Yun watched the two playfully bickering, and the corners of her mouth unconsciously turned up. The kitten in the cat carrier in her arms seemed to sense this relief and let out a soft purr.

She followed quietly behind, enjoying the rare lively time at the exhibition.

The three of them walked through the bustling exhibition area and finally arrived at a secluded corner of Hall W1.

Compared to the glamorous booths of the surrounding large manufacturers, the booth of Orange Micro Motor appeared particularly simple and even shabby.

On the simple printed cloth backdrop, the words "Chengke Micro Motor Co., Ltd." are printed.

Several small, unassuming exhibits lay quietly on a table covered with dark green velvet.

If you don't get up close and take a closer look, you would almost miss their existence.

Occasionally, tourists would pass by, glance at the nameplate densely covered with a long string of zeros such as "torque: 8mN·m/g" and "accuracy: ±0.001°", and look blankly at it, shaking their heads and walking away.

Meanwhile, professional buyers from home and abroad are currently crowding around the booths of companies such as Tiantian, Dongzhi, TDK, Fanaco, Tongkuai, Qianmenzi, and even Jingda, engaging in lively negotiations.

However, Orange Science's booth was not entirely deserted.

Paul, a foreigner with dark brown hair and blue eyes, was holding a few pages of A4 paper photocopied product manuals, which looked rather rudimentary, and was talking to Zhou Mingzhe with a furrowed brow.

He pointed to the parameters on the instruction manual from time to time, speaking very quickly, clearly with strong skepticism.

Originally sitting behind the booth, holding a thermos and looking rather bored, Director Feng immediately sprang to life as soon as he saw Chen Mo and his entourage, especially with the presence of their big boss, Chen Mo.

He jogged forward, bowed slightly, and greeted him with a broad smile: "Hello, Mr. Chen! Welcome to inspect our work!"

Feng Guofu quickly reported: "President Chen! Regarding Orange Technology's participation in the exhibition today... well, not many visitors, and among professional buyers, only Mr. Paul is currently talking to Xiao Zhou!"

Chen Mo waved his hand, indicating that he didn't need to stand on ceremony, and was about to introduce his companion.

Zhao Tiezhu had already taken the lead, grinning as he extended his hand: "You're Director Feng from Orange Technology, right? I'm Zhao Tiezhu, the marketing manager of Orange Technology! Just call me Brother Zhao for the sake of respect!"

Looking at Zhao Tiezhu's shrewd old face, Feng Guofu had no suspicions and hurriedly clasped his hands in his.

"Hey, Brother Zhao! Hello, hello! In the future, when purchasing oranges, please take good care of our brother company!"

He adopted a very humble attitude.

Chen Mo couldn't help but chuckle. Zhao Tiezhu was a kid who loved to take advantage of people based on seniority.

So he turned to Feng Guofu and pointed to Gong Yun: "You should be familiar with this, Director Feng. She is the general manager of our oranges, and she is the one who signed the document for the expansion funds that provided timely assistance to your Orange Science in January!"

Feng Guofu's enthusiasm instantly rose to another level, and with heartfelt gratitude, he bowed again to shake hands with Gong Yun.

"President Gong! Thank you so much! You were a lifesaver in January! Without your support, the expansion would have been impossible! We hope you will continue to look after us in the future!"

Gong Yun maintained a polite smile and nodded slightly: "Director Feng, you're too kind. Chengke deserves this kind of investment!"

After exchanging pleasantries, Zhao Tiezhu eagerly pulled Feng Guofu aside and began to enthusiastically discuss his dream of building cars by "enlarging micro motors".

Gong Yun walked behind the booth and sat down. She gently unzipped the cat carrier, took out the fluffy little kitten, and placed it on the table covered with green velvet.

Xiaomi's appearance was like a cute magnet, immediately attracting several couples with children to gather around.

With a smile, Gong Yun gently picked up Orange Science's brochure while protecting Xiaomi, and handed it to curious parents and children, cleverly using the cute pet to bring a touch of life to the otherwise quiet booth.

Chen Mo quietly walked over to Zhou Mingzhe and listened intently to his conversation with Paul.
“Mr. Zhou, I still insist. I must obtain physical samples of MYT-2.0 and MYT-3.0 to take back to our laboratory for comprehensive accuracy testing and verification!” “Words are meaningless. The parameters you’ve labeled, especially MYT-3.0’s ‘0.00001°/h’, are simply unbelievable!”

Paul's English had a distinctly European accent, his tone was forceful, and his bright green eyes were full of suspicion.

With the stubbornness of a technician on his young face, Zhou Mingzhe pointed to a smaller gyroscope core component, carefully fixed in the glass case, with a special matte black coating on its surface.

“Mr. Paul, we can provide you with a sample of MYT-2.0 for testing, but MYT-3.0 represents the limit of our current technology. It is extremely difficult to manufacture and has a very low yield. The one on display is the only engineering sample that can operate stably. It is impossible for you to take it away, as it involves core technology and confidentiality issues!”

“Zhou! And who is this?” Paul noticed Chen Mo approaching and interrupted Zhou Mingzhe with some displeasure, looking at the composed young man.

Zhou Mingzhe quickly introduced, "Mr. Paul, this is Chen Mo, the boss of our Orange Micro Motor and an important participant in our gyroscope project!"

Chen Mo nodded politely to Paul, then looked at Zhou Mingzhe with a gentle but undeniable authority.

"Mingzhe, you're right, the MYT-3.0 prototype cannot leave the exhibition stand!"

He turned to Paul, his gaze calm yet penetrating: "Mr. Paul, I understand your skepticism about precision, but could you tell me what the core of your question is?"

These foreigners, due to long-term media brainwashing, always have an inexplicable confidence in the techniques they have developed for growing flowers.

Paul was intimidated by Chen Mo's aura and toned down his arrogance slightly, but his doubts remained.

"Mr. Chen, please forgive my bluntness!"

The core components of your mechanical gyroscope are made of copper alloy, which is extremely rare in the field of modern high-precision gyroscopes!
Copper alloys were proven in the 60s to be insufficient in structural strength to support the stringent stability requirements of ultra-high precision gyroscopes, and have long been replaced by titanium alloys, carbon fibers and ceramic matrix composites!

I cannot understand how you can claim to achieve such near-theoretical precision as five zeros (0.00001°/h) using such 'outdated' materials?

This violates the fundamental principles of materials mechanics!

He spoke very quickly, clearly believing he had grasped the key flaw in OrangeTech's gyroscope technology.

Instead of directly refuting him, Chen Mo revealed a mysterious smile and posed a question: "Mr. Paul, you must be very familiar with the traditional advantages of using copper alloys in gyroscopes, right?"

Paul was taken aback, not understanding what Chen Mo was up to, but out of professional competence and confidence in his own knowledge, he subconsciously began to list.

"Hmph, copper alloys certainly have their advantages!"

First, high elastic limit and stability: For example, the commonly used CuBe1.7 beryllium copper alloy, through beryllium solid solution strengthening, can break through 1000MPa in elastic limit, far exceeding the 300-400MPa of ordinary titanium alloys on the market.

After precise aging treatment, the GP region precipitated inside can effectively lock dislocations, ensuring that the deformation attenuation rate of the precision spring under long-term vibration can be controlled within an astonishing 3%, while that of ordinary ceramic composite materials may exceed 15%!

Furthermore, copper alloys like PT18 show a measured wear of only 0.003 mm in miniature bearings, compared to 0.02 mm for carbon fiber, demonstrating a significant lifespan advantage.

He paused, then continued, "Secondly, it has excellent electrical and thermal conductivity."

CuBe1.7导电率能达到20%-25%IACS，导热系数100-120W/(m·K)。

This is an advantage that titanium alloys and ceramics cannot match for the precision gyroscope electronic connection components that require rapid conduction of weak current signals and timely dissipation of internal frictional heat.

"Third, precision molding capability."

Alloys like PT18 can be machined into micropores with a diameter of 0.125 mm, meeting the needs of ultra-precision components.

The Alloy K500 (Monell K500), with its exceptional dimensional stability, has always been an ideal choice for high-precision gyroscope components.

Finally, consider overall environmental adaptability.

Copper alloy coatings treated with modern environmentally friendly alloy catalytic technology have a porosity of less than 0.1% and maintain stable performance even under extreme temperature cycling of -55℃ to 125℃ and high humidity environments of 95%RH, perfectly avoiding the hydrogen embrittlement risk of traditional electroplating.

"Dispersion-strengthened copper, such as Cu-0.05%Al2O3, utilizes nano-alumina particles to pin grain boundaries, resulting in extremely high strength retention after high-temperature creep aging."

Every time Paul mentioned something, he would subconsciously look at Chen Mo, as if to prove that he was not an amateur.

Chen Mo maintained a gentle, encouraging smile throughout, nodding frequently to signal him to continue.

Finally, Paul finished recounting all the advantages of copper alloys in precision devices, his tone emphasizing the slight resentment of being tested.

"Mr. Chen, I acknowledge that copper alloys have these advantages. They were once the king of gyroscopes, and even in certain specific performance aspects, they remain a perfect balance that titanium alloys, carbon fiber, and ceramics cannot completely replace!"

"But!" He pointed sharply to the MYT-3.0 inside the glass display case: "Its fatal weakness—structural strength! Especially its resistance to micro-deformation under long-term conditions!"

"It simply cannot support the 0.0001°/h accuracy you claim. Material strength is an insurmountable obstacle in the laws of physics, which is why it has been phased out!"

Chen Mo's smile deepened, as if he had been waiting for him to say those words.

He gently pointed to the inconspicuous matte black coating on the core component of the MYT-3.0: "Mr. Paul, are you aware that our MTY series gyroscopes have a core technology called 'self-cleaning coating'?"

"Self-cleaning coating?" Paul was completely dumbfounded; this term was far beyond his expectations.

He hated the feeling of being controlled by the other party, especially in the "technological wasteland" he originally viewed with a sense of superiority.

But the incredible specifications of MYT-3.0, and the solution it might represent—a solution for the ultra-high precision gyroscope needed for the next-generation EUV lithography machine that President Winnick urgently needed—pulled at him like a hook.

The prospect of huge profits temporarily suppressed Paul's arrogance. He suppressed his impatience and stared intently at Chen Mo with his emerald green eyes.

"Mr. Chen, what do you mean?"

Chen Mo's smile carried an all-knowing confidence.

"So, what do you think about our 'self-cleaning coating'? Besides keeping core components clean, preventing dust interference, and extending its lifespan by 5 times?"
Could its other important function be to significantly improve the structural strength of the copper alloy substrate?

Especially in terms of resisting micro-deformation caused by long-term micro-stress and environmental erosion?

"Boom!" It was like a bolt of lightning striking my mind!
Paul's eyes widened instantly, and an incredulous light burst forth from his emerald green pupils!

He slapped his forehead hard: "Oh my God! The coating! It's that coating!"

Paul was so excited he was almost incoherent: "That's right! As long as we solve the most fatal weakness of copper alloys—its strength—my God! Its perfect elasticity, electrical and thermal conductivity, machinability, and environmental adaptability!"
It's a material that's practically tailor-made for ultra-high precision mechanical gyroscopes!
"Self-cleaning" isn't just about cleaning; it's a layer of "reinforced armor" mimicking that of a biomimetic ant, right?

The mystery that had puzzled Paul for so long was suddenly solved!
That seemingly ordinary black matte paint, which the technical director surnamed Zhou called a mysterious coating of "a certain ferrite oil-soluble paint," formed a dense, smooth, nanoscale composite film with a weak negative charge on the surface of the gyroscope component.

It not only prevents dust and moisture from adhering (self-cleaning), but more importantly, this film greatly enhances the structural strength and creep resistance of the copper alloy body.

This is like putting an invulnerable soft armor on an old master with profound internal strength but a slightly weak physique!
Copper alloy—the original king material of gyroscopes that was eliminated by history—has been given a new lease on life thanks to a revolutionary coating technology that makes it shine brighter than contemporary materials!
Having figured all this out, Paul was overwhelmed with emotion, so excited he almost jumped for joy.

He looked anxiously at Chen Mo and Zhou Mingzhe: "Mr. Chen! Mr. Zhou! I understand!"

"I fully understand the value of your technology. Please provide me with samples of MYT-2.0 and MYT-3.0; I need to take them back for verification testing!"

"As long as the test results meet the parameters, I guarantee with my personal reputation that I will do my best to recommend your gyroscopes to the company. This will be a new technology that will influence the future global precision manufacturing landscape!"

The development of science and technology has never been a straight up-and-down process, but rather a spiral upward pattern where one technology takes the lead and another takes the lead. Many old technologies have been revitalized due to breakthroughs in new materials.

For example, electric cars existed as early as 1830, but they were not widely adopted due to the limitations of battery technology at the time. Now that battery technology has developed and everyone wants to develop new energy sources, they have brought them back.

Chen Mo and Zhou Mingzhe exchanged a brief glance.

After a moment's thought, Chen Mo finally made a decision: "Mr. Paul, we understand your urgency. MYT-2.0 is a mature mass-produced product, and we can provide you with three sets for testing and verification."

"But the engineering sample of MYT-3.0, as Mingzhe said, is of great significance and unique, and cannot be removed from the exhibition stand. There is no room for discussion on this point!"

A flicker of disappointment crossed Paul's face, but it was quickly replaced by reason.

The MYT-2.0's accuracy of "0.001°/h" is enough to crush the Honeywell-controlled GG1389 fiber optic gyroscope (0.0015°/h), which is a huge success in itself!

This discovery was enough for him to report to the supply chain manager and secure further cooperation with Orange Technology.

He decisively extended his hand: "Deal! Mr. Chen! Please give me a sample of MYT-2.0!"

"Once our initial verification is successful, I will ask our supply chain manager to immediately send a formal invitation to your company to participate in our next-generation precision core component supplier bidding conference to be held at Holland headquarters this April!"

Zhou Mingzhe carefully took out three sets of packaged MYT-2.0 gyroscope modules and solemnly handed them to Paul.

Paul treasured it like a precious gem, carefully placing it into his personal protective case, which also contained samples of Dongzhihe TKD.

He bid a hasty farewell to the two men and quickly disappeared into the crowd at the exhibition.

Chen Mo looked in the direction where Paul had disappeared, smiled thoughtfully, and turned to ask Zhou Mingzhe.

"Oh, right, Xiao Zhou, we were so focused on the technical stuff that we forgot to ask which company Mr. Paul is representing. He's got quite the airs, making us fly all the way to Holland to participate in the bidding?"

Zhou Mingzhe recalled the information on Paul's business card and answered uncertainly, "It seems... it's called ASM? Asma?"

"Asma? ASM?" Chen Mo's smile froze instantly, and his pupils contracted sharply.

This pronunciation
Having witnessed the brutal power struggles within the chip industry chain in his previous life, Chen Mo was extremely sensitive to this name!

"Xiao Zhou! Let me see your business card."

Full name: Advanced Samiconductor Meterials Lithography, more commonly known in the industry as ASM!

ASM, the Dutch technology giant that holds the key to the world's most advanced DUV lithography machines and is hailed as the "crown jewel of the chip industry," is a prime example!
If the other party is seeking an ultra-high precision gyroscope at this time, it's definitely not for mass-produced DUVs, so it must be for EUVs!
OrangeTech's high-precision gyroscope has surprisingly piqued the interest of ASM's purchasing engineers? It might even become a part of their supply chain?
Even with Chen Mo's resolute will, at this moment, immense shock and a sense of absurdity surged through his entire body like an electric current!

Are high-precision gyroscopes on the international market really this bad?
He slowly turned his head and looked again at the few unassuming Orange Technology MTY series gyroscope samples lying quietly on the display stand.

Against a backdrop of deep green velvet, they seem to be quietly radiating a glimmer of light that could change the landscape of precision manufacturing, even in an inconspicuous corner.

The debate between China's flower-growing approach and North America's ultra-precise gyroscope route has already quietly begun!

Mechanical gyroscope VS Fiber optic gyroscope
Photoelectric analog gyroscope (market mainstream): I'm just an observer. I only produce consumer products and don't get involved in your high-precision, deviation-stable gyroscope business!

Indian: Hehe! Who said you weren't going to participate! I am who I am, a unique spark, and my gyroscope positioning technology is unparalleled!
There are three types of variable-track express delivery models in the world, namely, the three types of express delivery.

Here's a little-known fact: photoelectric analog gyroscopes not only have poor accuracy, but their deviation is also unstable. One second it might be deflected 0.001°/h to the left, and the next second it might be deflected 0.009°/h to the right. It's completely random, and you won't even notice it when using it on a mobile phone.

But it's being used in express delivery. What does that mean?
One second I veered 100 meters to the left, the next second I veered 900 meters to the right, second after second, the direction and distance of the deviation depended entirely on the results simulated by the photoelectric gyroscope positioning system.

In this way, no one knows where the Indian's package will ultimately be delivered, not even himself!
