我国车载GPS系统的应用现状与发展前景

GPS全球定位系统具有性能好、精度高、应用广的特点，是迄今最好的导航定位系统，国外GPS的应用已极为广泛．在中国GPS应用尚处于启动阶段，主要以车载导航系统为主，中国的GPS行业的潜在市场十分庞大．制约中国车载GPS系统发展的主要因素是：消费需求不强烈，缺乏行业标准，产品价格过高，电子地图开放不够；应采取相应对策．GPS车载系统在中国将有着较为广阔的发展前景，不仅有着巨大的市场需求，而且也将具有相应的产品供给与配套服务．

Applying Current Situation and Developing a Prospect of Chinese Vehicles

The GPS global positioning systenl has a good function, its accuracy is high, and its application is broad and characteristic, which is up to now the best navigation fixer systenl, as GPS application abroad is already extrenlely broad. Still in the starting stage in China, GPS application is applied first place to navigation systenl nlainly in vehicles, Chinese GPS industry potential market is very anlple. Restriction of Chinese vehicles has nlajor factor that GPS systenl develops： the consunlers demand is not intense; be short of the industry standard; the product price is excessive; the electron nlap renlains to be opened to the outside world. We should adopt the corresponding countermeasure specifically for above-nlentioned factors. GPS vehicles will have the conlparatively vast developnlent prospect in China with this systenl, which will not only have the gigantic nlarket demand, but also, the product will have large supplies and form a complete set services.
