摘要
主要研究了地面基准站GPS观测值模拟情况,分析了 GPS观测值模拟的意义、原理及流程、用到的数学模型等,并用编写的模拟软件模拟了武汉站的 GPS观测值情况。结果表明,本模拟方法所模拟的 GPS观测值和实测值很接近,能满足不同层次人员对GPS模拟观测值的需要。
An efficient static GPS measurement simulation of ground stations is studied in this paper, especially the significant, principle, flow chart and mathematical models used in GPS measurement simulation are analyzed. Then the simulation of GPS observation of Wuhan station is made. The results show that the GPS observations gained by the simulation method presented in this paper are very close to those observed. Therefore, the simulated GPS observations can meet various demands.
