PAYLOAD SUPPORT UNIT
The Payload Support Unit (PLSU) by Azista BST Aerospace is a sophisticated electronic device designed to operate a payload and receive, store, process & compress the payload data. It further includes encryption and a CCSDS engine. Additional functions are to control the payload temperature (Heat) and operate a focus mechanism (FOCM).
