Chapter 116 This flight control system is insane!
Thinking of this, many business owners who were originally preparing to purchase the Flying Bird S1 module as soon as possible exchanged subtle glances.
They all shared a common thought—the technology of the Flying Bird S1 was indeed breathtakingly awesome, but the name was seriously detrimental to the high-end positioning of their product.
Those who manufacture aerial photography drones worry that customers will think they're using a basic flight controller costing around 490 yuan; those who manufacture industrial inspection drones worry that clients will think the core modules aren't "professional" enough; and those who manufacture logistics and delivery drones worry that investors will associate the word "flying bird" with cheap products...
Even so, about 30% of the business owners have made up their minds—whatever the name, they just want to grab the first batch of goods.
There was no way they could refuse this module; it was simply too good.
As for the remaining 70%...
To be honest, because the name "Flying Bird" is so closely tied to the previous basic flight controller that cost 499 yuan, they are still somewhat hesitant.
Su Chen seemed to have been prepared for this.
He smiled slightly and gestured to the right side of the stage.
"Buzz—"
A deep, steady sound of rotors emanated from the side of the stage!
Almost simultaneously, nearly a thousand people in the audience turned to look at the sound and then collectively exclaimed in surprise!
A matte black quadcopter drone is slowly rising from behind the curtain on the right side of the stage!
This drone is not large, with its arms extended to about 60 centimeters wide, but its workmanship is extremely exquisite. The carbon fiber fuselage, the one-piece injection-molded arms, and the dual-axis gimbal camera mounted on the bottom—even from a distance of more than ten meters, the audience in the front row could see that the quality of this aircraft far exceeded that of the rough industrial drones on the market.
What's most eye-catching is that a palm-sized circuit board module is embedded in the center of the drone's belly—it's the Flying Bird S1 that was just shown on the big screen!
"This test drone is equipped with our Flying Bird S1 flight control and communication integrated module."
Su Chen's voice echoed throughout the venue, and at the same time, he held a tablet computer with a flight control interface displayed on the screen.
"Next, let me answer your questions with actual flight demonstrations."
As soon as the words were spoken, the image on the giant LED screen behind him suddenly changed!
An extremely clear overhead view appeared before everyone—
That's live footage transmitted from the drone's onboard camera!
The faces of more than 900 audience members were clearly visible!
The slight frown on Chen Jiaming's face in the front row, the meaningful smile on Han Shijie's face in the third row, and the wide-eyed look on Chen Weiguo's face in the middle area—all of these were clearly captured by the drone hovering 15 meters in the air!
And the image clarity—
It's not the blurry surveillance footage, but high-definition images comparable to professional-grade aerial photography!
"What the hell is this?"
The more than 900 people at the scene gasped in disbelief!
What surprised them wasn't that the drone could transmit images in real time—after all, Su Chen had just demonstrated the terrifying speed and ultra-low latency of the H-Link communication base station, so real-time image transmission didn't seem like a difficult task.
What amazed them was that the drone was hovering 15 meters in the air, at least 12 meters away from the nearest viewer, yet the facial features of everyone in the footage were so clear!
What does this mean?
This means that the flight platform driven by the Flybird S1 module has achieved a near-professional level of image transmission quality!
But what shocked them even more was yet to come—
Several key data points are displayed in real time in the lower right corner of the large screen:
Hovering height: 15.03m
Horizontal offset: ±0.02m
Vertical offset: ±0.01m
Image transmission latency: 11ms
Signal strength: 97%
"etc--"
Cheng Weiyuan, sitting in the front row, suddenly opened his eyes wide and stared intently at the horizontally offset number.
±0.02 meters?
That's two centimeters!
In an indoor environment without GPS signal boosting, this drone's hovering horizontal deviation was only two centimeters?!
This is impossible!
It's important to know that even the best consumer-grade drones on the market, in outdoor environments with good GPS signals, can only achieve a horizontal hovering accuracy of one to two meters. Industrial-grade high-end flight controllers, combined with RTK differential positioning, can at best achieve a level of ten centimeters.
And this drone was operating indoors! There was no GPS signal boost!
Two centimeters of hovering accuracy?!
This is simply an impossible number!
As you can see—
Su Chen's voice rang out at the opportune moment, his tone carrying a hint of calm amusement:
"The Feiniao S1 module incorporates our self-developed nine-axis IMU inertial measurement unit, working in conjunction with a BeiDou/GPS dual-mode RTK differential positioning system. In outdoor environments, the Feiniao S1 can achieve centimeter-level hovering positioning accuracy."
"And even indoors or in environments with poor GPS signal—like now—our Flybird S1, through a visual positioning system and IMU fusion algorithm, can still achieve hovering accuracy at the two-centimeter level."
At this point, Su Chen lightly swiped on the tablet.
The drone overhead suddenly moved!
It began to move slowly in the air above the venue with an extremely smooth motion, gliding from above the stage to the center of the audience, and then flying along the aisle in a complete figure-eight shape.
Throughout the entire process, the live feed on the big screen remained perfectly still!
It was as if an invisible hand was supporting a professional-grade drone camera, allowing it to glide smoothly through the air without any shaking, tearing, or lag.
"this……"
As someone who deals with drones every day, Chen Weiguo knows all too well how shaky the footage from drones in flight can be.
When their company's agricultural drones are in operation, the image transmission shakes so badly it's like an earthquake. Forget about seeing the details on the ground; staring at the screen for five minutes can make you feel carsick.
But now, this drone powered by the Flying Bird S1 is flying a figure-eight route indoors, and the image is as stable as a rock?
This is neither scientific nor reasonable!
During flight, drones are inevitably affected by various factors such as airflow disturbances, motor vibrations, and attitude adjustments, making image shakiness unavoidable.
But the footage from this drone—
It's as smooth as if it's installed on an invisible rail!
"alright--"
Su Chen slightly raised his hand, and the drone slowly flew back above the stage, hovering precisely in its original position.
The data in the lower right corner of the large screen has stabilized again: horizontal offset ±0.02m, vertical offset ±0.01m.
Exactly.
"Next, I will explain why the Asuka S1 can achieve such incredible flight stability."
Su Chen clicked the remote control, and the large screen switched to a pre-recorded comparison test video.
The video was filmed in an open outdoor test field, and the frame is divided into two halves.
The left half is labeled "Feiniao S1", and the right half is labeled "Industrial-grade flight controller of a certain brand" (the brand name is also blurred).
Two almost identical quadcopter drones hovered in the air, each with a measuring board marked with grid lines underneath.
The video title reads: Comparison Test of Hovering Accuracy in Level 5 Gust Environment.
In the footage, a wind speed flag stands next to the test site, fluttering in the wind—clearly filmed in a real, high-wind environment.
The video starts fast-forwarding.
The drone on the right side, labeled "Industrial-grade Flight Controller of a Certain Brand," was clearly drifting back and forth in the gusts of wind. The shadow trail on the measuring board below showed that its horizontal deviation fluctuated wildly between 30 and 50 centimeters. When the wind speed suddenly increased, the drone even deviated by more than one meter, and it took nearly three seconds to correct itself.
The drone on the left side is called "Feiniao S1"—
It was as if it had been nailed into the air by an invisible nail.
Under the same level 5 gust wind conditions and the same sudden change in wind speed, its horizontal deviation remained stable within three centimeters!
When a sudden gust of strong wind blew by, the drone on the right was blown more than 70 centimeters away before it stabilized, while the Flying Bird S1 on the left only shifted slightly by 2 centimeters and then returned to its original position in a fraction of a second!
After the 30-second test video finished playing, the final data summary appeared on the screen:
A certain brand of industrial-grade flight controller: average hovering deviation 32cm, maximum deviation 107cm, correction response time 2.8 seconds.
Flying Bird S1: Average hover offset 2.7cm, maximum offset 4.1cm, corrected response time 0.08 seconds.
The entire room fell into a deathly silence.
Then came a thunderous applause!
"Oh My God!"
The power line inspection boss next to Chen Weiguo slapped his thigh and exclaimed, "This flight control is insane! A three-centimeter drift in a level 5 gust of wind? My power line inspection drone drifts half a meter in a level 3 wind!"
"A corrected response time of 0.08 seconds?" Chen Weiguo's voice trembled. "That's thirty times faster than human reaction time!"
Chen Jiaming, sitting in the front row, looked extremely grim.
DJI's FlightCore flight controller has a hovering accuracy of about 15 to 20 centimeters in wind conditions of level 5, and a correction response time of about 0.3 seconds - which is already the top level in the industry.
The Asuka S1 is 3 centimeters and 0.08 seconds.
This gap isn't just a few tens of percent improvement; it's an order of magnitude of overwhelming superiority.
Wang Rui leaned closer and whispered, "If this data isn't fabricated... it will take us at least two years to catch up."
Chen Jiaming did not answer, but stared intently at the number "0.08 seconds" on the screen.
……
"The reason why the Asuka S1 can achieve such incredible flight stability is because we have integrated two core technologies into it."
Su Chen's voice rang out again, and a disassembled diagram of the Flying Bird S1 module appeared on the large screen, with each chip and component clearly labeled:
"The first core technology is our EIS electronic attitude compensation algorithm, for which we own completely independent intellectual property rights."
"EIS electronic attitude compensation algorithm?"
Nearly a thousand people at the scene showed expressions of curiosity.
"This is an AI-level flight control algorithm running on the Feiniao S1 main control chip."
Su Chen pointed to the location of the main control chip on the large screen and said:
"The working principle of traditional flight control systems is 'sensing-calculating-correcting'—first, sensors detect when the aircraft deviates, then calculate the required correction, and finally adjust the motor speeds to correct it. This process takes time, and this time difference is the fundamental reason why traditional flight control systems cannot achieve ultimate stability."
"And our EIS electronic attitude compensation algorithm doesn't 'detect the offset and then correct it,' but rather—"
Su Chen emphasized:
"Anti-deviation and begin correction before it occurs!"
"What?!"
An uncontrollable gasp erupted from the audience.
Correcting the drift before it even occurs? How is that possible? Can this flight controller predict the future?
"Our algorithm builds a real-time aerodynamic model of the flight environment."
Su Chen explained:
"Using meteorological data transmitted via a nine-axis IMU, barometer, vision sensor, and H-Link communication link, the Flybird S1's AI algorithm can analyze the surrounding airflow trends in real time at a frequency of two thousand times per second."
"When the algorithm detects a change in airflow—for example, a gust of wind blowing from the east—it doesn't wait for the wind to hit the aircraft before making corrections; instead, it adjusts the motor speed and attitude angle 0.05 seconds before the wind arrives."
"It's like a martial arts master who doesn't wait until a fist hits his face to start blocking; he's already in a defensive stance the instant the opponent throws the punch."
"I see!"
Han Shijie nodded in realization from the third row.
Having worked in the electronics manufacturing industry for twenty years, he has a deep understanding of chip computing power and algorithms. The "predictive flight control" that Su Chen mentioned is theoretically entirely feasible—but the prerequisite is that the chip's computing power must be powerful enough and the algorithm model must be accurate enough.
Given Hon Hai Precision Industry's capabilities in developing its own chips, achieving this certainly doesn't seem like a pipe dream.
Moreover, the airflow analysis frequency of "two thousand times per second" mentioned by Su Chen itself indicates that the performance of the main control chip of the Flying Bird S1 has reached the military-grade level!
"But software-level predictions alone are not enough—"
Su Chen abruptly changed the subject, zooming in on a specific area of the Flying Bird S1 module on the large screen—next to the two main control chips, there was a set of extremely tiny silver components arranged in a completely different manner from the chips:
"The second core technology is our OIS active vibration damping system, for which we own complete intellectual property rights."
"OIS Active Vibration Reduction System!"
Chen Jiaming, sitting in the second row, was startled.
"If EIS (Electronic Attitude Compensation) predicts and corrects flight attitude at the 'brain level' through software algorithms—"
Su Chen's voice became firm and powerful:
"So the OIS active vibration damping system eliminates vibrations and disturbances directly at the 'body level'!"
"Hardware-level vibration reduction?"
Cheng Weiyuan muttered to himself, his brows furrowed.
He knew all too well what this meant. No matter how powerful the attitude compensation at the software level was, it was still limited by the motor's response speed and the physical limits of the mechanical structure. If Su Chen had truly solved the vibration problem at the hardware level—then the Flying Bird S1 wouldn't just be a "good flight controller," but a "game-changer."
The disassembly diagram on the large screen was magnified further, and the set of silver components was highlighted:
"The set of miniature components you see here is the core of our OIS active vibration damping system."
Su Chen pointed to the big screen and said:
It consists of three parts—
"First, three sets of high-precision micro-MEMS gyroscope arrays sense the three-axis vibration of the flight platform in real time at a sampling frequency of 4,000 times per second."
"Secondly, the core sensor array of our self-developed magnetic levitation vibration-damping micro-support—the Flying Bird S1—is not rigidly fixed to the circuit board, but rather suspended and mounted via the magnetic levitation support. When the flight platform vibrates, the magnetic levitation support actively generates a reverse magnetic force to counteract the transmission of vibration."
"Third, the active vibration damping control chip—it works in conjunction with the EIS algorithm, one managing the 'brain' and the other the 'body,' working together to ensure the flight platform always maintains the most stable state."
"this……"
Everyone present gasped in shock.
Magnetic levitation vibration-damping miniature support? Allowing the core sensor assembly to be suspended and mounted?
This concept sounds like something out of science fiction!
Chen Jiaming suddenly turned to look at Wang Rui, both of them filled with shock.
DJI's FlightCore flight controller uses traditional rubber shock-absorbing pads, which can isolate motor vibrations to some extent, but the effect is limited. Su Chen, however, used magnetic levitation technology—meaning there is absolutely no physical contact, cutting off vibration transmission at its source!
No wonder the image transmission of the Flying Bird S1 is so stable, no wonder the hovering accuracy can reach three centimeters!
This is not even the same level of technology!
"Cutting-edge technology..." the power inspection boss next to Chen Weiguo muttered to himself, "This is simply cutting-edge technology..."
This statement expressed the sentiments of everyone present.
The EIS predictive flight control algorithm combined with the OIS magnetic levitation active vibration reduction system—a two-pronged approach of software and hardware—is the source of the Asuka S1's terrifying performance!
Traditional flight control systems are as vulnerable as Stone Age tools against modern weapons in the face of this combination of attacks!
At this point, many people who had previously hesitated because the name "Flying Bird" was too rustic had completely shifted their minds.
Does it matter if we call it a flying bird or a free-range chicken!
With this performance, this technology, these overwhelmingly superior data—even if this module were called "Iron Lump No. 1," they would still scramble to buy it!
A name is just an outer garment; technology is the soul!
With the core technology of the Flying Bird S1, their products can easily outperform their competitors, even if they just put a "sparrow" label on them!
