The FN820/820A is a fiber-optic integrated navigation system that integrates multiple sensors such as high-performance fiber optic gyroscopes, quartz flexible accelerometers, and satellite receivers. The sensors have been precisely factory-calibrated and undergo temperature compensation across the entire temperature range.
The FN820/820A 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 to achieve centimeter-level positioning accuracy. Based on high-performance integrated navigation fusion algorithms, multi-sensor data fusion is achieved, supporting the expansion of external odometers, DVL and other sensors. 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. The system is compact in size.
2. Strong adaptability: It has strong resistance to vibration and shock, and can operate at full temperatures ranging from -40℃ to +70℃.
3. High device precision: It adopts a high-precision 100 gyroscope, and the zero bias stability of the gyroscope is better than 0.006°/h(smooth for 100 seconds).
4. Good user experience: Supports multiple interfaces, adjustable output bandwidth, adjustable output protocol, and online upload of programs/parameters.
