GPS navigation sensor high precise inertial sensor with GPS
INS500 fiber integrated navigation system (the "ins") by the closed loop based on high precision fiber optic gyro, accelerometer and high-end GNSS receiver boards, navigation through multiple sensor fusion and decoding algorithm, provide high precision navigation position, velocity and position information, such as meet the requirement of high precision measurement and control, and main application fields include: The system has inertial/satellite integrated navigation mode and pure inertial mode.
When GNSS is invalid, it can enter the pure inertia mode (that is, GPS fusion has never been carried out after power is turned on, if the fusion is lost again, it belongs to the integrated navigation mode). After starting, it has accurate attitude measurement function, can output pitch roll course, and pure inertia can static north search.
