Lockheed selected Northrop’s Astro Aerospace unit delivered more 16 JIB assemblies for the first two GPS III satellites and provided more than 1,000 antennas for the predecessor GPS IIF and GPS IIR spacecraft configurations, Northrop said Wednesday.
The Air Force operates 24 GPS satellites and the first GPS III satellite is scheduled to join the constellation in 2015, according to Northrop.
“The GPS constellation is a key U.S. asset used by millions around the globe every day,” said John Alvarez, an Astro Aerospace general manager.
Alvarez added GPS III satellites are designed to provide users anti-jam features and position, navigation and timing services.
JIB antennas have monopole diameters of between a half-inch to 1 3/8 inches and lengths of up to 25 feet.
