Thermal analysis of the MR SAT spacecraft

Abstract

"In the year 2002, the University of Missouri-Rolla initiated a student satellite project. This project, MR SAT (Missouri-Rolla SATellite), aims to develop and place into orbit two satellites connected by a tethered link.

One of the important mission objectives of the project is to control the satellite temperatures using passive thermal control methods. Use of an active thermal control system consumes power and adds mass to the satellite. Thus, it is important to maintain small variations in temperatures using passive thermal control techniques.

This report describes the process of MR SAT's thermal model development using IDEAS/TMG software. Estimated spacecraft operating temperatures have been determined. Passive thermal control techniques are used for the analysis. Control methods were applied to ensure the thermal safety of the satellites over a large temperature range. The satellites were initially analyzed using the lumped code technique for a better understanding of the IDEAS/TMG results. Results presented that simulate the satellite for the worst-case temperature scenarios are in agreement with the allowable working temperature ranges of the respective subsystems"--Abstract, page iii.
