AI Technical Summary
Existing technologies lack a high-precision and rapid calibration method for dual-antenna vectors of satellite navigation systems in the inertial navigation system coordinate system, which hinders the effective fusion of information between inertial navigation systems and satellite navigation systems.
By employing filtering estimation techniques, the inertial navigation system and filter are initialized, the number of iterations and the noise covariance matrix are set, and the state transition and noise driving matrix are calculated using the real-time output information of the inertial navigation and satellite navigation systems. This enables high-precision dual-antenna vector calibration and projection in the inertial navigation coordinate system.
It achieves high-precision and rapid calibration of inertial navigation systems and satellite navigation systems, improves the attitude estimation accuracy and overall navigation performance of integrated navigation systems, and has good system compatibility and portability.
