- Abstract
Thermal Control System (TCS) is one of the critical systems in Thai Space Consortium-1 satellite (TSC-1), a microsatellite developed in Thailand. Prior to designing a thermal control system, the satellite’s temperature without thermal control shall be determined by thermal simulation. Although the simulation is a primary process in this state, its complexity (i.e., meshing, contact, etc.) takes time to complete. In order to shorten the time of temperature determination of satellites, the simulation shall be replaced by an easier approach. One of the simplest methods to investigate temperature trends for the satellite is a thermal calculation by nodal analysis. This paper focuses on a simplified thermal calculation for TSC-1 with rectangular prism configuration in a Sun-synchronous orbit by Microsoft Excel, using nodal analysis. The methodologies start with the determination of external heat loads incident on six sides of the satellite. Solar fluxes are calculated using the solar constant (1 AU) multiplied by solar projections in each anomaly. Besides, constant values of albedo fluxes and planetary fluxes are considered. Then, these external heat loads together with internal heat generated from electronics are applied to the energy balance equation to estimate the satellite’s temperature on each side. The calculation results are verified by comparing them with simulation results by Ansys Mechanical software under the same conditions.\\Keywords: Microsatellite, Nodal analysis, Thermal analysis, Thermal control system, TSC-1.
