Lockheed Martin is building a couple of small cube-sats as demonstration space-craft for its new LINUSS system (Lockheed Martin In-Space Upgrade Satellite System).
The concept is designed show how even smallish satellites can help upgrade satellites and even provide in-orbit refuelling and rescue tasks.
The initial concept is that LINUSS satellites will aid next-generation GPS satellites (the GPS 3F versions) which use Lockheed Martin’s own LM2100 satellite core platform.
The LINUSS craft have been developed with Tyvak Nano-Satellite Systems, a business in which Lockheed already has a commercial interest.
The aim is to use the cube-sats to prove the technology and then to scale up the design and functionality to larger vehicles.
