Abstract:

针对电离层周日变化特征分析了其可能对SCORE方法估算的硬件延迟稳定性的影响.利用BJFS以及XIAM台站的GPS观测数据,解算了位于太阳活动高年(2001年)和太阳活动低年(2009年)的卫星硬件延迟并分析了估算的硬件延迟的稳定性.研究发现,电离层周日变化对估算的硬件延迟稳定性具有一定影响,但是利用不同台站所得到的卫星硬件延迟稳定性在昼夜不同时间上的解算结果存在一定差异.电离层周日变化对利用BJFS台站数据解算的硬件延迟稳定性日夜差异较为明显,在太阳活动高年利用XIAM台站数据解算的硬件延迟日夜稳定性差异不很明显,由于XIAM台站处于电离层赤道异常峰附近,夜间电离层变化很大,因此对比中纬度地区,电离层周日变化对赤道异常峰附近地区硬件延迟稳定性解算结果的影响相对较小,但在太阳活动低年,其影响仍较为显著.
