摘要
全球定位系统(GPS)具有在海、陆、空进行全方位实时三维导航与定位能力的新一代卫星导航与定位系统。该系统性能好,精度高,应用广,是迄今为止最好的导航定位系统。随着该系统软硬件的不断完善,应用领域正在不断拓展。近年来,在上海吴淞口隧道工程、长江口抛吹工程、巢湖治疗工程等工程中应用了全球定位系统以辅助施工,取得了很好的社会和经济效益。本文就此作介绍、分析。
Global Positioning System(GPS) is a new generation of satellite navigation and positioning system which possesses the abilities of real time and 3D all azimuth navigation and positioning in sea, land and air. This system widely applied has good performance and high precision, so has been the best navigation and positioning system so far. With continuous improvement of its software and hardware its application area is also expanded continuously. In recent years GPS has been adopted in the engineering of Shanghai Wusong Estuary tunnel, the throw and blow engineering in the Changjiang River Estuary and the antipollution engineering of Chao Lake etc. for assisting construction and its good social economical benefits have been obtained. It is introduced and analyzed about these in the paper.
