Developed by SITAEL throughout multiple missions, the S-75 Micro-Satellite Platform is a consolidated product designed for the In-Orbit Demonstration / In-Orbit Validation (IOD/IOV) market. With its tray-based design and consolidated Payload module, it can guarantee strong flexibility while remaining a very compact bus.
S-75 Microsatellite Platform is based on two main assemblies, namely the bus module and the payload module. Platform subsystems are arranged inside aluminum trays in order to provide physical separation, flexibility and reduced MAIT effort. The main bus is physically separated from the payload(s) and integration can be performed separately, while a Payload Interface Unit (PLIU) provides power and data isolation to the instruments. In order to increase the overall system reliability, redundancy is implemented for most subsystems and units.
