Northrop Grumman Corporation has demonstrated the interface compatibility of the next-generation Advanced Extremely High Frequency (EHF) military communications satellite with user ground terminals using the new Extended Data Rate (XDR) waveform and protocols. Tests were conducted using a U.S. Army user terminal as well as a terminal configuration to be used by international partners participating in Advanced EHF.
Advanced EHF is a joint service satellite communications system that will provide global survivable, protected and assured communications for high-priority military ground, sea and air assets. Northrop Grumman's Space Technology sector is under contract to provide the communications payloads to Lockheed Martin, the prime contractor for the Advanced EHF system.The XDR capability and other advanced technologies will allow Advanced EHF satellites to provide 10 times more communications capacity and six times higher channel data rates than the predecessor Milstar system.
