This article introduces the development of a magnetic attitude control system (MACS) testbed for CubeSat, utilizing a spherical air bearing and a Helmholtz cage, along with the design, development, and verification procedure. Different test scenarios are presented, and experimental results confirming the effectiveness of the B-dot control algorithm were compared with numerical simulations.
For CubeSats requiring high pointing accuracy and slewing agility, ground-based hardware-in-the-loop simulations are strongly demanded to test and validate spacecraft subsystems and guidance, navigation, and control algorithms. In this article, a magnetic attitude control system (MACS) testbed for a CubeSat is developed utilizing a spherical air bearing and a Helmholtz cage. The design, development, and verification procedure of MACS is presented together with different test scenarios. To generate enough torque with the magnetorquer system in the dynamic testbed, the Helmholtz coil system of the testbed has driven to provide an augmented magnetic field. As an example of experimentation, the B-dot control algorithm was implemented to dissipate the angular momentum of the dynamic MACS testbed. The experimental results were compared with those of the numerical simulations.
