About
The SpaceTech cPCI-Serial-Space based Remote Terminal Unit (RTU) is designed to collect data from different avionic sensors and to control several avionic actuators. Its main part is a cPCI-Serial-Space based IO-Module that can be used centralized inside an onboard computer (e.g. small satellites) or decentralized in an RTU for large satellites with distributed I/Os. The RTU is scalable by using one or more I/O modules, and based on this concept, both cold- and hot-redundancy architectures can be realized. A dual-core LEON3 processor provides sufficient processing power to perform pre-processing of sensor data, and based on STI’s Core Avionics concept, the RTU also provides all protected supply voltages necessary to power the connected avionic components, with analogue and digital standard interfaces, LCL protected supply voltages, switched power outlets for heaters and cold gas thrusters, and connection to an onboard computer via CAN-Bus or SpaceWire.
