NAV300G Inertial Measurement Unit
NAV300G is a high-performance integrated navigation system. Built in three-axis gyroscope and three-axis accelerometer. It can be used independently as an IMU to output compensated angular velocity, acceleration, and temperature information. It can also be connected to an external GPS/BD receiver, odometer, etc. as a combined navigation system, outputting information such as speed, position, and attitude. The external dimensions and connectors are completely consistent with the foreign product STIM300.
The NAV300G can be used as an IMU instead of STM300, as well as an inertial or integrated navigation system.
