The UOSAT telemetry system

This paper describes the telemetry system for the satellite UOSAT) designed and built in the Department of Electronic and Electrical Engineering of the University of Surrey. The function of the telemetry system is to encode outputs of sensors, located around the spacecraft, into specified data formats prior to transmission via downlink transmitters. In addition, information relating to the status sub-systems and data from on-board experiments require similar encoding. The basic philosophy of the telemetry system aims at providing a continuous and comprehensive surveillance of spacecraft systems for engineering purposes and a number of data formats to for different ground station facilities.
