An attitude determination and control system (ADCS) testbed is required for ADCS examination and calibration. The testbed consists of an air-bearing platform, a triaxial Helmholtz cage, and a solar simulator.
By placing the user's ADCS on top of the testbed, the user may perform the functional test on each mode of the ADCS. This function is critical for users who are developing their ADCS algorithms.
Troubleshooting and debugging can be done on this testbed. This fully scalable testbed can also measure the mass properties of the device under test, which is optional for the customer.
By placing the whole satellite on top of the testbed, the user may measure the spacecraft's mass properties for settings on the ADCS.
This important procedure is crucial to extract the optimal performance of the ADCS and avoid unexpected outcomes in orbit.
