利用GPS精密差分信息实现舰船类目标关键部位间接测量

针对舰船类目标的结构特点,提出了一种利用双GPS载波相位差分结果,建立了载体瞬时坐标系和验前测定的各目标间相对位置关系,将主GPS天线位置修正到待测位置的方法。实际测试表明:使用该方法能得到待测位置各个时刻的三维位置和速度信息,精度优于单GPS修正方法,并且实现简单,数据稳定,易于工程应用。

Using GPS Precision Difference Information to Realize Ship Targets Key Part Indirect Measurement

For the structure characteristics of ships, a method that modify main GPS an- tenna position to the test location by using of two GPS carrier phase difference results to the establishment of instantaneous carrier coordinate system and prior determination of the rela- tive position relation between each target is presented. Real data test shows that using this method can get each time three-dimensional position and velocity information of the measured position, it is simple and easy to engineering application, and precision is better than that of single GPS correction method.
