The navigation equipment signal is usually solved by Kalman filtering software.In order to improve the Kalman filter noise coefficient and ensure that the algorithm can accurately calculate the navigation equipment signal azimuth value in a short time,a navigation equipment Kalman fiter azimuth solving correction technology based on LabVIEW is proposed,and the navigation equipment signal model and Kalman filter azimuth solving model are rapidly constructed by LabVIEW.The initial parameters of Kalman filter are modified.The test shows that this technology can shorten the correction time of Kalman filter noise coefficient effectively,and can be applied to the actual installation project.
