DESIGN OF AN INTERPLANETARY EXPLORATION TELEMETRY SUPPORT PACKAGE

Abstract

This student paper was produced as part of the team design competition in the University of Arizona course ECE 485, Radiowaves, and Telemetry. It describes the design of a telemetry support package for interplanetary exploration. Control and processing of telemetric signals between an earth based control station, an exploratory orbiter and probe pods are the focus of this design. Using this design data retrieval is achieved at a highly reliable rate of 1 error in 10^-10 bits. The exploratory orbiter, carrying a payload of probes, is launched and proceeds along its predetermined trajectory. Commands from the earth-based control station is used to send the orbiter to planetary destinations. The craft then establishes a stable non-geosynchronous orbit. Several probe pods are launched towards the planet at predetermined locations. These probe pods collect and send data, as well as system monitoring information to the orbiting craft. The orbiting craft then retrieves the signals generated by all pods and relays that information to an earth-based control station.
