By observing the simulation results, it can be obtained that automatic requests retransmission collaborative communications, improved the system reliability significantly. 通过观察仿真结果,可以得出结合自动请求重传的协同通信,系统的可靠性显著提高。
Through the observing preparation system, users can search catalogue, generate simulation chart on-line and provide some tools such as generating target list, cross-identification, distance calculation, etc. with the help of the observing preparation system. 通过观测准备系统,用户可以在线检索星表数据并生成模拟星图,同时提供一些辅助功能,如生成目标列表、交叉证认、计算距离等。
