利用北斗观测实验网解算北斗卫星差分码偏差
|
Abstract:
差分码偏差（DCB）是电离层总电子含量（TEC）监测和建模的主要系统误差，卫星DCB也是卫星导航系统导航电文的重要参数。研究了卫星DCB的估计算法，推导了不同基准下DCB的转换公式，利用北斗观测实验网解算了2013年北斗卫星的DCB。在同一基准下分析了北斗卫星DCB的稳定性，并与MGEX发布的DCB产品进行了比较分析。实验结果表明，该方法解算的北斗卫星B1-B2 DCB在-9~17 ns之间，北斗卫星DCB的稳定性优于0.4 ns；北斗倾斜地球同步轨道卫星（IGSO）卫星稳定性优于地球静止轨道卫星（GEO）和中圆地球轨道卫星（MEO）；利用北斗观测实验网解算的北斗卫星DCB与MGEX解算结果存在最大约1.7 ns的系统偏差，可能由于测距码的不一致性所致；接收机硬件材质的不同是导致接收机DCB差异的主要影响因素
