DGPS静态误差测量和在海洋地质调查中的应用

Static Error Measurement of DGPS Receiver and Its Application in Marine Geological Survey

介绍DGPS在海洋调查过程中的静态误差测量与使用其对调查船进行罗经校验的方法。依据罗经校验采集的试验数据,分析研究DGPS的稳定性和静态误差分布、定位精度对罗经校验方法的影响,提出其在海洋地质调查导航定位中的应用措施。

The method that static error measure and Gyro error of DGPS receiver in marine geological survey are introduced in the paper. The test data, collected by gyro error, are analyzed to study the stability of DGPS, the relation of static error distribution and positioning accuracy with gyro error method. And the authors finally propose the application countermeasures for navigation positioning in marine geological survey.
