Abstract:
Chinese BeidouI was completed in 2000 and has been opened for public use since 2003 The application of BeidouI data in the meteorological field is widely concerned. The feasibility of upper wind sounding with BeidouI is analyzed, experimented and validated. The threedimensional location of the radiosonde is determined in passive positioning way by injecting the realtime height, which is determined by using the realtime highprecision sounding data from radiosondes, into the Beidou positioning unit by twinflight test with the GPS and Beidou radiosondes, so the calculated winds at the sounding level are derived. The deviation between the two systems is about 05 m/s, which proved that the Beidou sounding system preliminarily meets operation requirements.
