Abstract
The present invention discloses a cubature Kalman filtering method suitable for high-dimensional GNSS/INS deep coupling, including: S, constructing a high-dimensional GNSS/INS deep coupling filter model; S, generating an initialization cubature point for the constructed filter model by using standard cubature rules; S, performing CKF filtering by using novel cubature point update rules. The present invention is suitable for high-dimensional GNSS/INS deep coupling filtering with high precision and high stability.
