摘要
介绍了自主开发的卫星重力测量数据处理软件GRASTAR,给出了该软件的整体设计框架和功能。该软件主要采用动力学法实现,应用CHAMP卫星和GRACE卫星的观测数据反演地球重力场模型。利用模拟方法验证了该软件的正确性,并利用GRASTAR处理了126 d的CHAMP卫星数据,解算出直到40阶次重力场模型的初步结果。
The GRASTAR developing independently had been introduced in this paper, which was used for processing satellite gravity data. The design framework and function of this software was then given. GRASTAR was used mainly to recover the earth＇ s gravity model by dynamic method, which was verified by simulated data. At last, 126 day CHAMP data were processed by GRASTAR, and a primary gravity model up to degree and order 40 was recovered.
