L3Harris Technologies has received contracts totaling $137 million for four navigation payload Mission Data Units (MDU) for future GPS III Follow-On (GPS IIIF) satellites.
Lockheed Martin, the prime contractor for GPS III/IIIF, selected L3Harris in 2018 to design and build the first two fully-digital MDUs, the heart of the satellite’s navigation payload. The MDU generates more powerful GPS signals and assures clock operations for GPS users, L3Harris said.
“The digital MDU is flexible enough to adapt to advances in GPS technology and future changes in mission needs,” said Ed Zoiss, president, Space and Airborne Systems, L3Harris. “The new MDU will also support a smooth transition for the U.S. Space Force’s GPS OCX ground control segment.”
The U.S. Space Force expects the first GPS IIIF satellite, which builds on GPS III adding new capabilities and technology, to be available for launch in 2026. According to L3Harris, the GPS IIIF MDU will provide improved capabilities over L3Harris’ 70-percent-digital MDU on the first ten GPS III satellites. The first four GPS III satellites have successfully launched and are now operational in the GPS constellation.
L3Harris Technologies is a global aerospace and defense technology innovator, delivering end-to-end solutions that meet customers’ mission-critical needs. The company provides advanced defense and commercial technologies across air, land, sea, space and cyber domains.
