Abstract:

In order to solve the problem that the azimuth zero position calibration method of current telemetry equipment doesn't meet the requirements of mobile measurement and control, this paper proposes an azimuth zero position calibration method based on rotor UAV and RTK surveying technology. The key algorithm of direction finding is deduced and the design of azimuth zero calibration system is completed. The calibration accuracy is improved by using the algorithms of data synchronization matching, outlier elimination and random error smoothing. The test result shows that the calibration accuracy of this method can meet the requirements of current telemetry equipment in S and Ka frequency bands.
