About
The GaAs Solar Panel with Coils (end edge) serves as the electrical power source for satellites. It incorporates built-in electromagnetic coils, which can be utilized for satellite stabilization. Released in 2017, the product has a guaranteed service life of 1 year and an estimated production/delivery time of 5 months. It has flight qualification, having been flown on the SiriusSat-1.2 satellites, launched on August 15, 2018. The product uses GaAs photo-electric converters and includes a super-diode protection circuit. It is compatible with SPUTNIX and ISIS CubeSats structures and features a built-in planar coil. The power and coils are scalable by using several panels. Each item comes with a calibration report. Additionally, there is a 13 mm diameter aperture at the panel’s center with M2 mount holes, suitable for sun sensors or similar payloads. The product cannot be adapted to customer requirements.
