Lockheed Martin performs orbital test of CubeSat repair system

Now, though, Lockheed Martin has performed the first successful demonstration of its LM LINUSS technology, which will focus on repairing small CubeSats, also referred to as nanosatellites. CubeSats are often the size of a loaf of bread or a shoe box, meaning they are particularly challenging to repair.

The LM LINUSS program uses CubeSats to repair CubeSats. To be precise, it uses a toaster-sized LM 50 2U CubeSat designed to perform highly-automated rendezvous and proximity operations (RPO).

Lockheed Martin demonstrates key CubeSat servicing technologies

During the recent in-space demonstration, one satellite acted as the target while the other acted as the service spacecraft. The service vessel used online navigation algorithms and artificial intelligence software to successfully rendezvous with the target.

"The LM LINUSS pathfinder is an excellent example of how Lockheed Martin is investing in innovation in the real world," explained Johnathon Caldwell, Lockheed Martin vice president and general manager of Military Space. "Agile development, cloud-based operations, and smallsat platforms came together at speed and in orbit, where the real test of technology occurs. Through the accomplishments of LM LINUSS, Lockheed Martin is pioneering how future small and medium class missions will be upgraded on-orbit, and continuing to develop critical, breakthrough technologies that keep our customers ahead of ready."

Lockheed Martin explained that the service CubeSat also demonstrated several other technologies, including a low-toxicity propulsion system and machine vision. It also allowed the defense and aerospace giant to validate the use of 3D-printed components for its CubeSat repair system.
