摘要
对’９２、’９６国家高精度ＧＰＳＡ级网进行了不同方案的整体平差，研究了利用全国范围的高精度ＧＰＳ网进行我国地壳形变监测的数据处理和分析方法。利用具有可比性９２Ⅲ和９６Ⅱ平差方案建立了在ＩＴＲＦ９３框架下的我国块体运动模型，并与ＮＮＲ－ＮＵＶＥＬ１Ａ模型进行了比较；同时研究了我国的板内块体运动模型，这一结果与地质结果较为一致。
The integrated adjustment for national high precision GPS A order network is carried out in different precepts; and the way of using nationwide high precision GPS network to process and analyze data of the lithosphere deformation monitoring of our country is studied. The rigid block movement model under the ITRF93 frame is established by using 92Ⅲ and 96Ⅱ adjustment precept, which have the same reference frame and mutual initial epoch; and it is compared with the NNR NUVEL1A mdoel. At the same time, the model of the movement between rigid blocks is studied. The result is in correspondence with geological result.
