Payload Controller

The payload controller is a subsystem dedicated to the interface between the payloads and NanoAvionics CubeSat and Microsatellite buses. It has a number of different interfaces for payload connection and can buffer data from payloads. It also controls the S-band transmitter or transceiver to transmit the buffered data to Ground Station.
