讨论了一种船栽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。该方案通过切换船栽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。

This thesis is aimed at overcoming the drawbacks of Shenzhou manned spaceship tracking and controling for no backup, using of tracking the QPSK data transmission signals with the Shipborne Tr＆c System to implement the backup program for the first time. From three aspects of the theoretical analysis, such as the QPSK data transmission signals modulation characteristics, Shipborne TY＆C System tracked the composition and carrier demodulated received. Tracking through the FM receiver receiving the QPSK data transmission signals, the static and dynamic tracking tests verify tracking of the program feasibility and effectiveness. The technology features with no additional auxiliary equipment on the basis of shipborne TT＆C system, significantly reduces the risk of failure of the spaceship tracking.
