Nano and micro satellites are progressively becoming the backbone or platform via which academia, industry and governments across the globe pursue space for research and education, economics, technological demonstration, security and many more. This concept is making space accessible, affordable, and reliable, especially for new entrants in the space field. One of the ways to achieve this is making environmental testing of satellites inexpensive. We present in this paper, the performance evaluation of a comparatively inexpensive thermal vacuum testing system, equipped with a thermoelectric device that uses the Peltier principle of heat generation and/ or absorption. The thermoelectric device is a commercial-off-the-shelf (COTS) component with a cooling capacity of 16.9 W. The testing system does not require liquified nitrogen or silicon oil for simulating cold conditions. In addition, the testing system is capable of vacuum thermal cycling and balancing tests within -45 ℃ to +75 ℃, well beyond the minimum requirements of the ISO-19683. These characteristics make the testing system simple, reproducible, and affordable. We evaluated performance parameters of the Peltier device as functions of cold side temperature.
