About
The ADCS Testbed supports satellite missions that require pointing and attitude determination capabilities, by facilitating calibration, measurement of mass properties, and tests and validation of ADCS algorithms. It consists of an air-bearing platform, a triaxial Helmholtz cage, and a solar simulator, and is easily customizable to fit customer-specific requirements.
Included hardware: Triaxial Helmholtz Cage, Air-bearing Platform, Solar Simulator. Software functions (Testbed-TYF customer support software): mass properties measurement; platform attitude estimation and wireless communication; platform center-of-mass calibration assistant; dynamic magnetic field control according to selected orbit.
Mass properties measurement: the low-disturbance-torque environment enables precise measurement of center of mass, moment of inertia (MOI), and product of inertia (POI) — essential for ADCS design and validation.
