摘　　要：随着我国北斗卫星导航探空观测系统升级换代工作逐步推进,降低L波段探空系统测风数据差异的需求尤为迫切。利用无人机GNSS-RTK定位信息研究新的标定方法,相较传统标定手段,避免人为因素干扰、极大的降低测量误差,新的标定方法更加科学有效,对保证测风数据的有效性,提高高空气象观测数据质量具有重要应用意义。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.
