导航定位卫星作战信息支援效能评估方法研究

An Evaluation Method Research for Evaluating Navigation and Position Satellite Effectiveness of Supporting Operational Information

通过分析导航定位卫星的信息支援任务集合，建立了相应的效能评价指标体系；

In this paper , an information supporting operational task set of navigation and position satellite is analyzed .

可用的第三方电磁波信号包括地面广播电台、电视台、通信台站、直播电视卫星和导航定位卫星系统等发射的信号。

The illuminating sources available include signals transmitted by local broadcast station , television station , communication station , satellite for living broadcast television , satellite for navigation and position and so on .

GPS即全球卫星定位系统（globalpositionsystem），广泛应用于导航定位的卫星通信系统。

GPS ( Global Position System ) is widely used in navigation and positioning satellite communications system .

卫星接收机是现代通信技术发展的产物，已在卫星导航定位、卫星电视直播以及卫星数字广播等领域中得到广泛的应用。

Satellite signal receiver is the outcome of the development of the modern communication techniques , it has been widely used in many fields , such as satellite navigation 、 satellite television living broadcast and satellite digital broadcasting , etc.

由于各独立卫星导航定位系统的卫星星座规模有限，可提供的卫星定位服务的精度、可靠性无法得到保障。

Because of limited satellite constellation of each independent system , the precision and reliability of positioning service can not be guaranteed .

补充介绍了美国、俄国、欧盟、中国和印度等国在发展卫星导航定位系统方面的某些内容，并阐述了日本准天顶卫星导航定位系统和间谍卫星的情况。

This paper makes additional introduction to some contents of the satellite navigation system developed by America , Russia , European Union , China and India , and expounds the situation of the quasi-zenith satellite navigation system and spay satellite developed by Japan .
