Last week, the University of Alabama in Huntsville (UAH) announced that it developed a cybersecurity software for the U.S. Army Space and Missile Defense Command (USASMDC).

The software began performance testing on one of Lockheed Martin’s In-space Upgrade Satellite System (LM LINUSS™) technology demonstrator CubeSats. The software, Small Satellite Defender, is an intrusion detection system designed for small satellites.

The Small Satellite Defender – created by UAH students, UAH Center for Cybersecurity Research and Education (CCRE) staff and USASMDC cybersecurity engineers – will continue to run for multiple weeks collecting data and periodically transmitting data to the ground station. The students are members of the Space Testing and Resiliency Simulation team, or STARS, who perform small satellite research and development for USASMDC.

“We are extremely proud of our students. Originally, they wrote the software and completed it for USASMDC, and then Lockheed Martin approached us to collaborate with their LM LINUSS™ program,” said Dr. Tommy Morris, Director of the UAH CCRE, a part of The University of Alabama System. “Our students restructured their code to run on LM LINUSS™, passed tests on a Lockheed Martin laboratory model and developed an in-flight test plan with Lockheed Martin engineers.”

The Small Satellite Defender runs with relatively low power, monitors for satellite specific threats and requires very low bandwidth. The software is collecting data for multiple weeks and periodically transmitting the cyber status to the ground station. The initial test results indicate the Small Satellite Defender software performed as intended, and the application passed all in-flight tests.

Lockheed Martin began on-orbit operations in early 2023 with the LM LINUSS™ CubeSats. The internally funded satellite system was part of Lockheed Martin’s mission to validate essential maneuvering capabilities through rendezvous and proximity operations for future space upgrade and servicing missions.

“We are thrilled that LM LINUSS™ is being utilized above and beyond its original mission objectives, which demonstrates how Lockheed Martin is leading innovation by reconfiguring satellite missions on-orbit,” said Bob Behnken, Lockheed Martin’s Director of Technology Acceleration for their Ignite organization. “We are proud to partner with UAH to provide this unique STEM opportunity for their students and to help strengthen cyber resiliency.”
