Key highlights
Payload Controller is a dedicated subsystem that serves as the interface between the satellite’s payload and its data storage unit in micro- and nano-satellite platforms. It supports multiple electrical interfaces, provides data buffering capabilities, and is fully compatible with S-band and X-band radio subsystems for efficient transmission of buffered data to ground stations.
