摘要

It is envisaged that the role of reconfigurable systems in space communication would be of great significance in the near future. The software-defined radio (SDR)-based radio frequency (RF) receivers are widely used recently in space communication applications. This paper presents the design of an SDR-based spacecraft telemetry (TM) system using the open-source software toolkit GNU’s not unix (GNU) radio and an approach for implementing the same using the universal software radio peripheral (USRP™) N200. To our knowledge, this is the first work on the TM system that uses GNU radio for the design and simulation and USRP for the implementation. We propose an end-to-end TM system that addresses dynamic phase and frequency corrections as well as gain corrections via digital automatic gain control (AGC). The designed system has been simulated and verified with various channel imperfections commonly seen in space communication, such as additive white Gaussian noise (AWGN) and Doppler shift. The simulation and implementation results show the flexibility and adaptability of the SDR system in realizing a spacecraft TM system.
