Two downlink antennas that are the fastest of their kind to operate in space are being integrated into the protected communications payload built by Northrop Grumman Corp. (NYSE: NOC) for the fourth advanced extremely high frequency satellite.
The company delivered the super high frequency array unit, as the antennas are called, in early March to system prime contractor, Lockheed Martin (NYSE: LMT) , in Sunnyvale.
These high-speed downlink phased array antennas, the first to operate at 20 GHz in space, provide assured point-to-point connectivity using electronically steerable beams that reach military users at fixed-site and mobile terminals.
Under a hybrid integration plan, Lockheed Martin is integrating the satellite bus unit within the system module while a team from Northrop Grumman simultaneously completes remaining payload integration.
Northrop Grumman produces phased array antennas, which are a new technology developed specifically for AEHF satellites. High-speed downlink phased array antennas are the first of their kind to operate at 20 GHz in space. High-speed uplink phased array antennas operating at 40 GHz provide direct radio frequency beams electronically rather than by moving reflectors mechanically.
Northrop Grumman is a leading global security company providing innovative systems, products and solutions in unmanned systems, cyber, C4ISR, and logistics and modernization to government and commercial customers worldwide. Visit www.northropgrumman.com for more information.
