Design of UHF receiving equipment for micro/nano satellite

Abstract： In view of the complexity and huge system of UHF(ultra-high frequency) telemetry ground station of conventional micro/nano satellite，a simple ground receiving scheme using AD9361 is designed. The equipment is composed of RF front-end, baseband processing and upper computer. Through the analysis of RF chain and sensitivity, the feasibility of the scheme is ensured theoretically. Through the experiment of the analog signal source receiving, the results show that the scheme of the UHF receiving equipment is feasible and has been applied in the micro/nano satellite signal receiving test.
