摘要
１９９６年１月，俄罗斯完成了对ＧＬＯＮＡＳＳ的２４颗卫星布设，并开始整体运行。ＧＬＯＮＡＳＳ与 ＧＰＳ相比无 Ｓ／Ａ政策影响，与 ＧＰＳ联合使用可提高单点定位的精度。因此 ＧＰＳ与ＧＬＯＮＡＳＳ的联合应用具有广泛的应用前景，但前提是必须知道ＧＰＳ与ＧＬＯＮＡＳＳ的坐标转换参数。本文分析了计算坐标转换参数的模型及计算方法，介绍了俄罗斯国防部第２９研究所为确定适用于俄罗斯地区的ＧＰＳ与ＧＬＯＮＡＳＳ转换参数而进行的ＧＰＳ、ＧＬＯＮＡＳＳ观测及数据处理，认为：在中国地壳运动观测网络基础上，计算适用于中国地区的ＧＰＳ与ＧＬＯＮＡＳＳ的坐标转换参数是可行的，也是必要的。
In January 1996, Russia accomplished GLONASS 24 satellites' constellation. Compared with GPS,the GLONASS has no S/A effect. The combination of GPS and GLONASS improves positioning of the accuracy of single point. That is why it has good application future. The application of combining GPS and GLONASS is based on knowing the coordinate transformation parameters. This article analyses coordinate transformation models (Bursa Model and Molodensky Model),reports the GPS and GLONASS observations and data processing to determine the coordinate transform parameters between GPS and GLONASS exactly fitting the area of Russia. It is possible and necessary to calculate GPS and GLONAS transformation parameters fitting the China region based on the crust movement monitoring network of China.
