摘要 水下DGPS定位系统是我国近些年研制的一套水声定位系统,该系统经过了在三亚、抚仙湖等地区的试验,得到了较高的定位精度。利用Argo浮标剖面数据,将海水视为水平分层均匀介质,计算声速剖面,根据Snell定律从理论上推出了理想情况下水下导航定位系统中浮标的可布设范围和水下DGPS定位系统浮标阵的可定位范围。 Underwater by China in recent years. DGPS positioning system is a set of hydro-acoustic positioning system developed The system was experimented in SanYa and FuXianhu etc, and has achieved a high precision. Supposing the seawater as horizontal stratified homogeneous medium, this paper computes the water velocity profile with Argo surveying data. According to Snell rule it deduces the tolerably emplaced area of buoys in DGPS system, and the tolerably position extension of some network which composed of positioning buoys.
