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