A desired orientation in outer space, with a specified level of precision, is a mission requirement for every spacecraft based-on payload condition. Technically, Attitude Determination and Control Sub-system (ADCS) is responsible for satisfying this requirement which primary focused on Low-Earth Orbit small satellite missions. To make the analysis realistic, ground-based ADCS simulation and testing platform was established under Thai Space Consortium (TSC) program at National Astronomical Research Institute of Thailand, Chiang-Mai, Thailand. Normally, the Helmholtz coil is a primary equipment to simulate the Earth’s magnetic field that is a part of ADCS. In this research, the Biot Savart’ s Law was applied to describe the magnetic distribution through the mechanism of Helmholtz coil (circular and square) based on International Geomagnetic Reference Field model in three-axis. The facility’s objective is testing and verification of the TSC’s small satellite research and developing program. Therefore, in this paper, we introduce hardware-in-the-loop test bench with specific devices, their performances, and future extensions in progress.
