عنوان مقاله [English]
In order to be sure from true function of satellite’s Attitude determination and Control Subsystem (ADCS) and its parts, some tests are needed to be done in part or subsystem level. One of the useful tools for doing these tests is Helmholtz Coil. This tool is usable in functional tests and calibration of satellite’s magnetic sensors and actuators, in Hardware In the Loop (HIL) tests of ADCS subsystem, and also in related tests to residual magnetic of satellite’s part. In this paper, we study mathematical equations of Helmholtz coil, propose design procedure and requirements, also introduce set of functional and identification tests for evaluating the constructed Helmholtz Coil. By obtaining results and finding the mathematical model of Helmholtz Coil, preparations for designing closed loop control system to eliminate environmental magnetic disturbances and create desired magnetic field by Helmholtz coil are provided.
