基于虚拟仪器技术的水下定位导航系统

UGPS BASED ON VIRTUALINSTRUMENT TECHNOLOGY

在人类对水下世界进行探索和研究工作中,定位导航技术一直是一项重要的研究内容,声学定位系统和GPS系统联合组成的水下GPS系统可以获取载体在水下工作时的更多信息。水下GPS系统是一个跨多学科,包括空间物理学,水声学,GPS技术,坐标系变化等的综合性很强的复杂系统。本文从理论和实际两方面来讨论采用短基线定位系统和GPS系统联合构成的水下GPS系统,并用虚拟仪器技术来实现。

Positioning and navigation Technologies have shown to be extremely important instruments in the study and exploration of the underwater world. The underwater GPS（UGPS）, combined with acoustic positioning system and GPS, could definitely attain more information of the operational vehicle under water, and the UGPS is a relatively complex system with comprehensive technologies like geometry of earth, acoustic, GPS, coordinate system, etc. This paper gives a brief overview of research and discusses theoretical and practical issues that arise in the solution of the underwater GPS （UGPS） system, and final work will be done by virtual instrument technology.
