The FD211 product is a fiber-optic integrated navigation system that integrates a variety of high-performance sensors such as fiber optic gyroscopes, accelerometers, and satellite receivers. The sensors have been precisely factory-calibrated and can achieve temperature compensation across the entire temperature range. The FD211 is equipped with a built-in satellite receiver that supports four satellite positioning systems and can operate independently with the Beidou system. It also supports RTK differential positioning, achieving centimeter-level positioning accuracy. Based on high-performance integrated navigation fusion algorithms, multi-sensor data fusion is achieved, supporting the expansion of external odometer, DVL and other sensors. Even in the event of satellite loss of lock, it can still maintain good navigation data output for a period of time. This product can continuously and stably output navigation information such as attitude, heading, speed and position in various harsh environments. It features high precision, small size, light weight, stability and reliability, and can operate stably in wide temperature and high vibration environments.
Typical applications：
This product can be widely applied in fields such as autonomous driving, unmanned aerial vehicles, ships, special vehicles, and submersibles.
1. Strong adaptability: It has strong resistance to vibration and shock, and can operate at full temperatures ranging from -40℃ to +70℃.
2. High device precision: The zero bias stability of the gyroscope is ≤0.2 °/h(smooth for 10 seconds).
3. Good user experience: Supports multiple interfaces, adjustable output bandwidth, adjustable output protocol, and online upload of programs/parameters.
4. High output frequency: The maximum output frequency of IMU is 4000Hz, and the maximum output frequency of navigation information is 200Hz.
