Xi'an Precision Measurement and Control PA-GS01 MEMS integrated navigation

The system is a high-precision integrated navigation system based on an inertial platform and integrated with satellite navigation technology. Built-in high-precision inertial device,GPS/BD single-frequency dual-mode satellite navigation system,three-axis magnetometer,and air pressure sensor. It can realize flexible switching of multiple working modes such as integrated navigation,AHRS,and vertical gyro.
The integrated navigation fusion algorithm is stable and mature. Fast alignment,fast response,fast convergence,and accurate positioning. The three-position attitude is stable and reliable,highly unaffected by the environment,and positioning is fast and accurate. It can meet the navigation applications of cities,forests,canyons and other terrains.
