摘　　要：利用GPS数据处理软件GAM IT中的运动学定位模块（TRACK）,对1 Hz和3 s采样的GPS动态观测点数据进行定位,结果较好地得到了海上浮标和空中运动目标的真实运动轨迹;对静态观测数据包括30 s采样和1Hz的观测数据,依据基线长度小于10 km、10-100 km之间以及大于100 km 3种情况进行处理,对定位结果精度的误差统计结果表明,在观测数据质量较好的情况下,静态定位水平分量精度能够达到或接近5 mm。1 Hz and 3 second sampling GPS data of 2 moving objects using the kinematic module TRACK of the GPS data processing software GAMIT had been processed, and well obtained the true trajectory of the buoy on sea and moving target in the air. In the case of static positioning, the GPS data of 3 baselines had been proccessed, which are of less than 10 km ,between 10 and 100 kin, as well as more than 100 km. Accuracy analyses were also carried out. Statistic results show that in the case of high quality of data, the accuracy of horizontal components can reach or be close to 5 mm.
