Abstract: The U.S. Naval Analysis Laboratory has accomplished improvement of a robotic system able to servicing satellites 22,000 miles above Earth. This know-how might remodel house operations by enabling in-orbit repairs and upgrades of satellites, probably saving billions in alternative prices and increasing satellite tv for pc lifespans.
Naval Analysis Laboratory Announcement, October 8, 2024 | Studying time: 4 minutes
For the primary time, satellites might obtain the identical upkeep and upgrades that different navy gear routinely will get, because of a brand new robotic system developed by the U.S. Naval Analysis Laboratory (NRL). The know-how just lately accomplished its closing testing part, marking a big advance in house infrastructure upkeep.
A Mechanic’s Store in House
“The navy usually fixes plane, tanks, ships, and vehicles that break. We improve plane and ships with the most recent radars, computer systems, and engines,” explains Glen Henshaw, NRL senior scientist. “Satellites are the one costly gear we purchase that may’t be repaired or upgraded as soon as they’re within the discipline, and this prices the taxpayer cash.”
The Robotic Servicing of Geosynchronous Satellites (RSGS) system goals to vary this example. Positioned in geosynchronous orbit roughly 22,000 miles above Earth, these satellites serve essential navy, authorities, and industrial communications roles.
Testing for House Situations
The system underwent rigorous thermal vacuum testing, simulating the acute circumstances it’ll face in house. Engineers examined all parts, together with avionics, cameras, lights, and two robotic arms able to performing numerous upkeep duties.
“NRL’s Workforce RSGS has spent practically 10 years targeted on the purpose of finishing this primary of a form, robotic servicing payload,” notes William Vincent, NRL RSGS program supervisor. The system is scheduled for launch in 2026.
