| 摘 要： | BERNESE Extended CODE Orbit Model(ECOM)光压模型是GPS精密定轨中广泛采用的一种光压模型,本文首先介绍了该光压模型构造,并分析了该模型对三种不同类型GPS卫星的适用性。为定性了解ECOM光压模型中各参数对精密定轨的影响,采用附加参数统计检验方法对九个模型参数定性进行了评价。本文结果说明,采用ECOM模型时,实际估计八个参数较为合理。

| Abstract: | The Extended CODE Orbit Model(ECOM) was widely used in the precise orbit determination(POD) of GPS satellite.First,the frame of the ECOM was presented and its availability to all kinds of GPS was studied.The efficiency of the parameter in ECOM was evaluated by extraparameter hypothesis testing.It is shown that it's reasonable to estimate the 8 parameters in the POD of GPS satellite with ECOM. |
