Abstract

The Tracking, Telemetry and Command (TT&C) systems for space vehicle had gone through two main stages, which were separate systems and carrier unified systems, now its developing trend is advanced Spread Spectrum Unified TT&C(SS-UTTC) systems. The delay-locked is a key technique of Tracking, Telemetry and Command (TT&C) systems. This paper gives a new non-coherent delay-lock loop scheme based on coherent characteristic and analyses its acquisition and tracking performances for Doppler Shift and test the performance in experiment.
