中文摘要：
北极蕴藏着丰富的资源,冰川融化使得夏季北极地区的航行成为可能,北极地区战略地位凸显。为了保障北极地区活动的安全性,精确导航定位是重要基础保障,本文分析了我国北斗卫星导航系统当前星座及未来全球星座在极区的可用性。详细分析了利用北斗卫星导航系统在极区进行导航、定位服务的基本性能,分析其优缺点,并提出了可能的应对方法。
英文摘要：
The strategic position of Arctic area and its rich natural resources are becoming increasingly important,while the northeast and northwest passages through the Arctic are receiving much attention as glaciers continue to melt.Hence,GNSS will play a significant role due to its unique advantages as Arctic navigation and positioning are particularly significant to guarantee the security of activities in that environment.The Beidou regional satellite navigation system was established successfully,and is developing into a global system enveloping the Polar Regions.In order to evaluate Beidou performance in the polar area,Beidou availability with present and future constellations,and the combination of Beidou with GPS are analyzed.The latent challenges to the navigation services provided by GNSS in polar area are discussed and possible solutions provided.We argue that the current BD2 can not satisfy the navigation requirements,but with a global BDS,it is possible to provide navigation services independently in Arctic area.
