用DGPS双天线系统校验定位辅助设备的方法探讨

Discussion of the DGPS Dual Antenna System Method for Checking the Auxiliary Positioning Devices

随着GPS技术的快速发展,使用DGPS定位的精度越来越高,这就为物探船上定位辅助设备的精确校准与校验提供了可能。通过对发现六号物探船定位辅助设备的校准与校验,初步形成了一套比较可行的作业方法。此文结合校验方法及其可行有效性分析,详细阐述了校验方法,并试图对校验误差来源进行探讨,以期提高对定位辅助设备校准与校验的精确度。

with the rapid development of GPS technology, the accuracy of DGPS positioning becomes higher and higher, which makes it possible for precise calibration and verification of positioning auxiliary device in geophysical prospecting ship. Through calibration and verification of the auxiliary equipment of the Discoverer Six, a set of feasible operation method for calibration and verification of the auxiliary equipment have been developed. In this paper, calibration method and feasibility of calibration and verification have been described in detail, and error sources during calibration and verification are discussed in order to improve the calibration and verification accuracy of positioning auxiliary equipment.
