Celestia Satellite Test & Simulation (C-STS) products

The Instrument SCOE is a turn-key system providing electrical and protocol interfaces to a satellite Instrument (camera, synthetic aperture radar, etc.)  during development and AIT of the Instrument. Instrument SCOE sometimes called Payload SCOE allows operating stand-alone Instrument through the electrical interface that is later provided by the spacecraft. Typically, these SCOE’s provide power, control signals (discrete, serial, bus) interfaces and monitor the instrument. In addition to the physical interfaces, the SCOE also uses the spacecraft communication protocols, timing, sequences, etc and can include automated sequences. The SCOE can be operated stand-alone through the local GUI or connected to an overall test system such as a CCS via the remote (LAN) interfaces.

Radio Frequency Special Check-Out Equipment (RF SCOE) is an integrated system that is used to validate the RF subsystems of a satellite during integration and testing. As most satellite RF subsystems are unique per satellite, the RF SCOE is based on a combination of C-STS standard Onboard, RF Interface, and Software products in combination with COTS equipment to meet the customer requirements. Most commonly this RF subsystem is integrated into an overall 19” rack. However, C-STS has also delivered elements for integration into the RF SCOE as a sub-contractor.

The RF Suitcase is an integrated RF subsystem for ground station and satellite radio frequency compatibility testing (RFCT). The RF Suitcase (or RFS) integrates part of the real spacecraft RF chain into a transportable system that can generate representative Telemetry at RF level and receive Telecommands.
