In June 2017, SSL was awarded the contract to design and build the satellite servicing spacecraft vehicle for the US Defense Advanced Research Projects Agency (DARPA)’s Robotic Servicing of Geosynchronous Satellites (RSGS) program, which is designed to inspect, repair, and augment geosynchronous satellites and plans to include a refueling payload to extend the life of satellites that are low on propellant. SSL joined the Naval Research Laboratory, the Charles Draper Laboratory and Maxar's robotics divisions in Brampton, Ontario and Pasadena to develop the servicer. The servicer is designed to refuel commercial satellites, and global satellite operator SES is the first commercial customer to sign up to use the services for a satellite life extension mission.
