重力卫星的星载GPS精密定轨

Determination of Precise Orbit Using Onboard GPS Data for Gravity Modeling Oriented Satellites

    摘要
  • 摘要: 利用CHAMP和GRACE卫星的实测数据,研究了重力卫星的精密定轨问题,并针对几何法精密定轨方法给出了一种有效的星载数据编辑策略;在PANDA软件的基础上,处理了101 d的实测数据;通过与不同机构卫星轨道的比较、激光测距观测值检验以及重力场模型恢复等外部检核的方式,分析了卫星轨道的精度。结果显示,本文的简化动力学轨道的精度为2~3 cm;几何学轨道的定轨精度为3~4 cm,适用于重力场模型的解算。

     

    Abstract: Both kinematic and reduced dynamic orbit determination for CHAMP and GRACE satellites are studied.Data cleaning is a crucial step for kinematic POD.In the process,a reduced-dynamic orbit is firstly determined to detect outliers and cycle slips in the data.The accuracy of the precise orbit is assessed by comparing them with DEOS,JPL and TUM reduced dynamic orbits as well as with SLR data.Furthermore,gravity field models recovered from the computed kinematic orbits are compared with those derived from TUM kinematic orbits.The comparison results confirm a high quality of our computed kinematic orbits.
