Link quality is crucial when designing communication subsystems for satellite system including on-board and ground equipments. The purpose of the link quality evaluation is to guarantee the system performing in a reliable manner considering the constraints in limited power, radio spectral and costs. This paper will introduce the evaluation method for Bit Error Rate (BER) parameter to verify the link quality of the telemetry downlink between small Earth observation satellite and its ground station with International Telecommunication Union‘s recommendations taken into account. Case study is also done for simulating and estimating link quality for a small Earth observation satellite Telemetry downlink.
