It has been announced by Data Device Corporation (DDC) that the US Naval Research Laboratory (NRL), developer of the robotic servicing payload for RSGS, has chosen DDC’s SCS750 Single Board Computer (SBC) for use on the Robotic Servicing of Geosynchronous Satellites (RSGS) program for the Defense Advanced Research Projects Agency (DARPA).

RSGS will provide an on-orbit satellite servicing vehicle that will transform US space operations in Geosynchronous Earth Orbit (GEO). As the lead payload developer for the program, NRL selected DDC’s SCS750 SBC due to its processing capabilities, radiation performance (in particular with the best in class upset rate of one uncorrectable error in 80 years), known reliability and flight heritage (TRL-9 since 2013).

Several of DDC’s SCS750 SBCs will be used in the RSGS satellite, providing for all aspects of control including attitude control and robotic control, along with video processing.

SCS750 single board computer highlights:

Reliability

Proven in space: TRL-9.
Utilised with confidence in the most critical missions.
One in 80 year board level SEE rate (GEO).
TID greater than 100krad(Si); SEL immune.

Optimised performance

Incorrect transactions are never generated.
Seamless error correction.
Software controlled Speed/Power: 200-1800 MIPS; 7-30W typical.
Error-corrected memory (SDRAM and EEPROM).
cPCI; MIL-STD-1553, serial/parallel interfaces available.

Dan Veenstra, Space Business Unit Manager of DDC’s Poway CA location where the SCS750s are designed and manufactured, stated: “DDC is excited to be supporting NRL on this very important DARPA program that will be a game changer for the maintenance and upgrading of satellites. Since inception, more than 20 years ago, our electronic components (more than 100,000 shipped) and TRL-9 Single Board Computers have experienced zero failures in space, which will help to ensure the success of the RSGS Program.”
