Lockheed Martin’s In-space Upgrade Satellite System (LM LINUSS™) has successfully demonstrated the important role that small satellites can play in maintaining critical space architectures. The system, made up of two LM 50™ 12U CubeSats, achieved highly-automated rendezvous and proximity operations (RPO) while on-orbit, allowing for complicated yet precise maneuvering across multi-satellite constellations. This enables on-orbit servicing coordination and upgrades at scale in any orbit. The RPO demonstration was part of Lockheed Martin’s mission to validate essential maneuvering capabilities for future space upgrade and servicing missions.
During the demonstration, one of the LM LINUSS CubeSats acted as the designated servicing vehicle, navigating a flightpath towards the second CubeSat, which represented the resident space object (RSO). As the servicing vehicle approached the RSO, on-board guidance algorithms made final real-time adjustments to complete its rendezvous operations. Its culminating success was declared when the CubeSats maneuvered in a proximity of one another that demonstrated high confidence in conducting future on-orbit servicing missions for customers.
“The LM LINUSS pathfinder is an excellent example of how Lockheed Martin is investing in innovation in the real world. Agile development, cloud-based operations, and smallsat platforms came together at speed and in orbit, where the real test of technology occurs,” said Johnathon Caldwell, Lockheed Martin’s vice president and general manager of Military Space. “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.”
In addition to RPO, the CubeSats also accomplished additional technology demonstrations while on-orbit, including performing automated maneuvers and using artificial intelligence to fly coordinated flightpaths, maintaining connection with a secure cloud-based architecture for mission telemetry, tracking and control, showcasing the company’s advanced SmartSat™ software, demonstrating miniaturized Space Domain Awareness capabilities, and validating new onboard high-performance processing, low-toxicity propulsion, inertial measurement units, machine vision, and 3D-printed components.
LM LINUSS is part of Lockheed Martin’s LM 50 smallsat family and is considered the most capable pair of CubeSats in geosynchronous Earth orbit today, based on customer community feedback. The spacecraft have higher bus density, payload accommodation, and on-orbit processing than any other CubeSat, which helps enable revolutionary mission capabilities in the future. The system is the collaborative integration of the company’s mission electro-optical payload deck with a next-generation bus from Terran Orbital Corporation. LM LINUSS and other Lockheed Martin pathfinders are helping create a more sustainable future, safely adding mission life and more.
