Description
The GA3390 is a small, control grade GPS/INS integrated navigation system. The GA3390 contains MEMS inertial sensors, optionally, it can add magnetometers and/or pressure sensors to measure the azimuth and altitude respectively. The GA3390 internally uses a Kalman filter and temperature compensation technology to provide accurate position, speed and attitude information. The data update rate of the system is 100Hz. The GA3390H is designed to meet Military Standard's environmental requirements. The GA3390 provides high performance yet at a low cost and is being used for UAV and automobile navigation.
