摘要
就GPS测量大地高在GPSurvey软件上的高程转换与规律性数学面拟合进行对比论证,结合有水准测量资料的GPS控制网数据处理试验,通过分析重合点上的高程残差,总结出GPSurvey软件上的高程转换结果与规律性的数学面拟合结果基本趋于一致,这在实际应用中,解决了解析法还需编程计算的缺点,突出软件网平差转换功能快捷方便的优点。
The paper discusses elevation conversion of GPS geodetic elevation on GPSurvey software with regularity fitting mathematics face. Through the analysis of the elevation residual on coincidence point combined with control net data handling test, the paper concluds that the result of elevation conversion in GPSurvey software is nearly as the same as the result of regularity fitting mathematics face and resolvs the shortcoming of analytical method which need programming calculates and also concluds that the software adjustment is convenient.
