摘要
根据GPS定位技术原理,探讨了GPS高程异常模型的3种数学拟合模型及数据的粗差检验和显著性分析的理论,并应用上述理论分析了实测资料及其精度,最后讨论了其应用前景。
According to the principle of GPS, Discuss three model of GPS leveling, the theory of data gross error detection and analysis of evidence. Analyse the data and its precision. Forecast the application of GPS leveling.
