FD620A/630B fiber optic integrated navigation system

The FD620A/630B product is a fiber-optic integrated navigation system, which 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 built-in satellite receivers of 620A/630B support four satellite positioning systems and can operate independently with the Beidou system. They support RTK differential positioning to achieve centimeter-level positioning accuracy and can also be connected to external satellite receivers. Based on high-performance integrated navigation fusion algorithms, multi-sensor data fusion is achieved, supporting the expansion of external odometers, DVL and other sensors. Even in the event of satellite loss of lock, it can still maintain good navigation data output for a relatively long 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, light weight, stability and reliability, and can operate stably in wide-temperature and high-vibration environments.
