Error Analysis of Multi-beam Sounding Based on Non-uniform StraightLine Survey of the Survey Ship
摘要
Abstract
The basic premise of multi-beam sounding system for operating is to maintain survey ship in uniform linear motion,but multi-beam survey in the non-uniform motion state of the actual operation is ubiquitous,the commonly used attitude measuring device based on the principle of acceleration measurement will be affected at this time,however.Therefore,this paper is based on the analysis of multi-beam attitude error,and we study the attitude error in two cases of straight line acceleration and U type turning,then by comparing of data between INS attitude and GNSS three antenna attitude to annlysis the characteristics and degree of attitude error in non-uniform motion state.Experiments show that when the survey ship to do a straight line to accelerate the movement,this will make the pitch angle produce a greater error,and when the survey ship turns,this will make the roll angle to produce a greater error.It has a certain reference value for guiding the actual measurement of multi-beam.关键词
