四点长基线深海定位模型建立方法及精度分析
Observation data simulation and positioning accuracy analy-sis of a 4-point long-baseline model in deep water
摘要
Abstract
High-precision underwater positioning is a widely used technology that is of great significance for the maintenance of national maritime security, maritime rights and interests, and national economic construction. Ac-cording to the propagation characteristics of radiation in water, the long-baseline deep-sea positioning model is es-tablished using the hyperboloid positioning method. The accuracy and distribution of the positioning error of the 4000 m underwater source in the range of 10 km2 are obtained via computer simulation. Results show that the po-sitioning accuracy at the center of a buoy network is the highest, and the sub-meter level is obtained. The position-ing accuracy decreases with increasing distance from the center position.关键词
