High precision fiber optic gyroscope (FOG) location set by high-precision closed-loop fiber optic gyroscope (FOG) and high reliability and high stability quartz flex accelerometer attitude heading reference system POS510 recovery, and professional GNSS board combination, the specially designed GNSS / INS data processing software for processing, can provide accurate position and attitude information, and three-dimensional angular velocity and acceleration dynamic information, is a high precision positioning and orientation system. POS510 can spread GLONASS and Beidou satellite receiving function, and according to different application environment extended range gauge, altimeter sensors and other ancillary to further improve the accuracy and applicability of the system, can provide direct reference information. It is widely used in mobile measurement of maps and aerial photogrammetry mapping equipment (such as aerial camera and lidar, radar).
