Remcom Receives NASA SBIR for Simulation of Wireless Channels for Artemis Spacesuits and Lunar Rovers

STATE COLLEGE, Pa., Sept. 23, 2025 /PRNewswire/ -- Remcom has received a new Small Business Innovation Research (SBIR) Phase I contract from NASA to develop enhanced wireless channel modeling capabilities for antennas mounted on astronaut spacesuits and lunar vehicles. The award expands on Remcom's previous work supporting NASA's Space Communications and Navigation (SCaN) program and the Artemis lunar exploration missions.

While earlier efforts centered on macro-scale lunar network planning, the current focus helps NASA engineers design and verify robust communication links for astronauts operating on the Moon's surface via enhancements in Wireless InSite^® 3D Wireless Prediction Software. New innovations will address challenges created by complex, layered materials in modern spacesuits and their impact on antenna radiation and transmissions. Wireless InSite will leverage Huygens surfaces to integrate near-field and far-field antenna behavior around astronauts and the structures they interact with in the lunar environment. This will reveal performance tradeoffs for various antenna placements and protocols, such as 3GPP sidelink, to optimize device-to-device (D2D) communications between astronauts. Additionally, acceleration methods will be employed to significantly reduce simulation runtimes by one to two orders of magnitude, allowing for more expedient analysis of propagation in dynamic scenarios.

The project will address Artemis mission-specific needs with resulting technologies that will also benefit commercial wireless device design, especially for wearables and on-body sensors in complex environments.

"Modeling antennas in close proximity to complex structures like spacesuits introduces new electromagnetic challenges that are not well addressed by traditional simulation approaches," said Greg Skidmore, Remcom's director of propagation software and program manager of the effort. "This contract provides the opportunity to prototype unique solutions that ensure astronauts stay connected, whether they're exploring craters or conducting operations outside line-of-sight, providing NASA with a more realistic understanding of communication performance in dynamic lunar scenarios."
