| 摘 要： | 对美国1998年发射的月球探测器LP任务阶段共19个月的双程测距测速轨道跟踪数据进行了精密定轨，对定轨结果通过轨道残差及重复弧段差异进行了精度评价。利用LP正常任务阶段三个月的轨道跟踪数据进行了月球重力场模型解算，通过重力场功率谱、轨道残差和月球自由空气重力异常对解算模型进行了精度评价。结果表明精密定轨及月球重力场模型解算合理。对进一步融合嫦娥一号轨道跟踪数据和LP数据解算自主的高精度月球重力场模型具有参考意义。

| Abstract: | Two-way range and Doppler data in 19 months are used for precision orbit determination of lunar exploration mission LP.The orbit determination accuracy is assessed by orbit residuals and orbit overlap differences.The lunar gravity field model is solved based on 3 months tracking data of LP during nominal phase,and the model accuracy is evaluated by gravity field power spectrum,orbit residuals and lunar free-air gravity anomaly.Results show the reasonability of precision orbit determination and lunar gravity... |
