Satellite platforms and payloads include mixed-signal boards integrating control functions, links between payloads and the on-board computer, and analog and RF interfaces ensuring a variety of functions such as thermal control and telemetry in addition to star trackers and altitude control functions in the case of the on-board computer.
Control units are built using FPGAs, microprocessors (MPU) and application specific standard products (ASIC) and standard logic to implement simple features, while connectivity between different sub-systems is ensured with low-speed interfaces including CAN or legacy buses and LVDS (low-voltage differential signaling) for medium-speed communication. Each sub-system and board is supplied from the power bus provided by the power distribution units with local low-dropout (LDO) linear regulators or DC-DC converters.
ST’s space portfolio includes a range of Defense Supply Center Columbus (DSCC) JANS and QML Class V (QML-V) and European Space Components Coordination (ESCC) qualified Rad-Hard discrete devices including Schottky diodes and rectifiers, bipolar transistors and power MOSFETs as well as integrated circuits including gate drivers, voltage regulators, data converters, LVDS and standard logic devices.
