介绍北斗二代卫星系统(BDS)3种卫星天线相位中心改正模型,分析对比不同模型对精密定轨、卫星钟差以及精密定位的影响。结果表明,ESA/ESOC的BDS卫星天线相位中心改正模型在精密定轨、卫星钟差和精密定位方面均优于其他模型结果,建议在北斗高精度数据处理中采用。
Three antenna phase center models of Beidou system (BDS) satellites are introduced. Differences and influences of these three models are analyzed with respect to precise orbit, satellite dock offset and precise positioning. Numerical results indicate that the precision of ESA model is superior to other models results. We suggest using the ESA model in BDS high precision data processing.
