KVH high-precision fiber optic gyroscope products adopt photonic chip technology

KVH Industries recently announced that it has integrated photonic chip technology into high-precision fiber optic gyro products and delivered new photon gyroscope inertial measurement devices to selected users at the end of December last year (Photonic Gyro) Prototype of IMU). Developed by KVH engineers, the photonic chip technology is designed to achieve centimeter-level positioning accuracy and meet the demanding requirements of autonomous vehicle developers.

During the product development period, Photonic Gyro IMU prototype tea will show its powerful navigation performance, its angle random walk (ARW) and bias instability are excellent, the above two parameters are autonomous driving The two most important performance parameters of the vehicle.

The angular random walk or noise value of the Photonic Gyro IMU prototype is less than 0.0097 kWh, which is very low and supports extremely high precision navigation. In addition, the product has a very low bias stability or drift value, measured at 0.02 degrees / hour. Low drift is the core parameter for maintaining position and providing high-precision steering measurements that are critical to vehicle safety.

With the development of this photonic chip technology, KVH will enable mass production of high-performance, low-cost, high-performance inert systems that will use less labor. KVH will manufacture fiber optic gyroscopes and fiber optic gyroscope-based inert system products at Tinley Park, Illinois, USA.

Company executive Kits van Heyningen said: "The sensor fusion technology will play a vital role in the operation of autonomous vehicles. The company's fiber optic gyroscopes and fiber-optic gyroscope-based inertial measurement devices are highly accurate, and the product can be For unmanned vehicles. With high precision and photonic chip technology, the company's photon gyroscopes are the core enabler of autonomous driving technology."

KVH's patented photonic chip technology is still in the waiting for approval phase, using a photonic integrated circuit for fiber optic gyroscopes and fiber-optic gyroscope-based inert systems, which are considered by the industry as high-performance inert sensors.
