Abstract Keywords
The number of small satellites has increased drastically in
the last decade. Thermal testing is a necessary step for
numerous projects. It includes thermal modeling, manu-
facturing of thermal models, thermal vacuum tests.
Thermal modeling is often important to establish feasibi-
lity and verify requirements for a mission. The work is
time and money consuming. The study presents a new
approach to thermal model testing and thermal vacuum
testing. It enables us to improve the quality and flexibility
of modeling, as well as reduce the duration of testing the
expensive thermal experimental models and samples in
the thermal vacuum chamber. According to the deve-
loped methodology, the calculation of simplified thermal
models should start at the stage of structure and thermal
model development. Simplification and acceleration of
the thermal modeling is achieved by thermal parameters
analysis which leads to higher accuracy of the thermal
model. This allows for determining the necessary para-
meters of a thermal model without additional tests on the
early stages of the project and choosing the simplest
thermal scheme with optimal temperature control system
