Calibration method for L-band upper-air sounding system based on GNSS-RTK positioning of UAV
With the gradual promotion of the upgrading of the Beidou satellite navigation sounding observation system in China,it is particularly urgent to reduce the discrepancy of wind measurement data of the L-band upper-air sounding system.This paper innovatively uses the UAV GNSS-RTK positioning information to study the new calibration methods,compared with the traditional calibration methods,to avoid the interference of human factors,to greatly reduce the measurement error,and to calibrate more scientifically and effectively,and to improve the quality of high-altitude meteorological observation data,which are of great practical significance of application.
