Designs of the broadcast ephemeris parameters and algorithms of GPS and GLONASS, two major operational satellite navigation systems today have their respective features. GPS和GLONASS作为当今世界上在轨运行的两大卫星导航系统,其广播星历参数的设计和算法各具特点。
Other shortcomings included : short operational range; navigation and communication equipment were almost none-existent, and its bridge offered very low visibility. 其它的缺点包括:短操作航程、几乎没有导航和通信设备,而且它的舰桥提供了非常低的视野。
Finally, with the experiment on the variety of simulated operational states of navigation, it was analyzed for the response n the stability > the safety of this system. 最后通过具体的测试试验模拟了实船在各种工况下运行,根据试验数据分析了系统的实时动态特性、稳定性、安全性。
In this paper, an information supporting operational task set of navigation and position satellite is analyzed. 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;
