Details
Specifications

SNC500E-A0/A1/A2 integrated navigation system consists of two parts: inertial measurement components and navigation components. The inertial measurement components include inertial devices such as fiber optic/MEMS gyroscopes and MEMS accelerometers, which are responsible for completing inertial measurement and compensation. The navigation components include satellite navigation boards and calculation interface circuits. The system utilizes multi-sensor fusion navigation algorithms to provide high-precision attitude, velocity, and position information to meet the measurement and control requirements.
