SatTherm is a simple thermal analysis tool for small spacecraft that has been developed in collaboration with the Mission Design Center at NASA Ames and San Jose State University. A comparison of the ease of use and accuracy of results is made between SatTherm, and the commercially available Thermal Desktop software by Cullimore & Ring Technologies. Several benchmark cases are presented, including a model of the small spacecraft PharmaSat. The non-steady temperatures predicted by the SatTherm model agree with those predicted by the Thermal Desktop model within 4°C or less. This demonstrates that SatTherm can be a useful tool for the early design stage of a small spacecraft.
