多波束测深系统的高精度差分GPS数据实时优化

Real-time correction of high-accuracy DGPS data for the multibeam bathymetric survey

摘要: 多波束海底地形探测是目前世界上最为先进的海底地形探测方法.高精度的差分GPS定位是实现多波束系统高精度测深的最基本前提.在海上探测作业过程中,由于客观原因,差分GPS数据存在偶然误差,影响多波束测深精度.本文提出对差分GPS数据进行航速、航向平滑处理、误差定位点位置推算的实时优化方法和数学模型,并给出实际实现的例子.

Abstract: The multibeam bathymetric system is presently one of the most advanced methods in the world for marine bathymetric surveys. The use of a high-accuracy DGPS is the premise for getting the high-accuracy bathymetric data by multibeam echo sounding. In multib
