8K22
Product Introduction
The 8K22/8K22A integrated navigation system measures the relevant data of the carrier through internal MEMS inertial measurement units of different accuracies and high-dynamic satellite navigation receivers. It uses integrated navigation algorithms or pure inertial navigation algorithms to calculate the attitude, velocity, and position information of the carrier. The product can be used in unmanned aerial vehicles, test rockets, and other carriers.
