Abstract: 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.
