TY-MIG-2A
MEMS Inertial Product
Product Introduction
The TY-MIG-2A integrated navigation system is equipped with a high-accuracy positioning and orientation receiver and a high-performance MEMS inertial measurement unit. In environments with good satellite conditions, it can achieve rapid positioning and orientation with dual antennas and maintain position, velocity, and attitude accuracy for extended periods. Based on satellite positioning conditions, it can switch between pure inertial navigation and integrated navigation modes. It can be applied to navigation and attitude measurement for various aircraft, vehicles, and ships.
