讨论了一种船载USB系统跟踪数传信号可行性的方案,为实现船载USB系统对飞船目标跟踪功能的备份提供了一个新的思路,该方案通过切换船载USB系统中跟踪接收机软件状态的方式来实现,此方法已成功应用于跟踪过境数传信号目标的跟星训练中,试验结果表明该方案是有效的和可行的,该方案在充分利用现有测控设备功能,不增加辅助设备功能的基础上,可以显著提高测量船执行神舟飞船测控任务的可靠性。
A scheme of tracking the feasibility of digital signals by shipboard USB system is discussed. A new idea is provided for the backup of the spacecraft target tracking function by shipborne USB system. By switching the tracking receiver software in the shipborne USB system, This method has been successfully applied to tracking star tracking of transit digital signals. The experimental results show that this scheme is effective and feasible. This scheme makes full use of the functions of the existing measurement and control equipment without any additional assistance Based on the function of the equipment, the reliability of the survey ship to perform the measurement and control tasks of the Shenzhou spacecraft can be significantly improved.
