The sixth Lockheed Martin-built Advanced Extremely High Frequency (AEHF-6) protected communications satellite successfully completed its On-Orbit Test (OOT) period on Aug. 27, 2020.

"Successful OOT demonstrates that all space vehicle performance requirements have been met and that we are on track for satellite control authority handover to Space Operations Command before the end of the year," said Erik Daehler, director of Lockheed Martin's Protected Communications mission area.

"This is a great accomplishment for the industry-government team, bringing incredible capability for our warfighters."

AEHF-6 will be part of a geostationary ring of ten satellites in the AEHF-MILSTAR constellation delivering global coverage for survivable, highly secure and protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms.

The satellite adds increased resiliency and advanced capabilities to this constellation, which ensures the ability to transmit data anywhere, anytime.

Besides U.S. forces, the AEHF system also serves international partners Australia, Canada, the Netherlands and the United Kingdom.

AEHF-6 was successfully launched about five months ago, on March 26, from Cape Canaveral Air Force Station, Florida, aboard a United Launch Alliance Atlas V 551 rocket. The launch was the first mission launch for the U.S. Space Force.

As prime contractor, Lockheed Martin Space developed and manufactured all six AEHF satellites at its production facility located in Sunnyvale, California.

The AEHF team is led by the Production Corps, Geosynchronous Earth Orbit/Polar Division, at the U.S. Force's Space and Missile Systems Center, located at Los Angeles Air Force Base, California.

Air Force Research Laboratory Tracks Sporadic E
Kirtland AFB NM (SPX) Sep 10, 2020
Researchers at Air Force Research Laboratory (AFRL) in New Mexico, have discovered a new way to track and characterize a phenomenon called "Sporadic E" naturally occurring in the upper atmosphere, where large structures of dense plasma form. These plasma structures, which occur at mid latitude locations around the world, disrupt radio frequency (RF) electromagnetic waves (or simply "radio waves") and impact both DoD and civilian radio systems in positive and negative ways, depending on the applica ... read more
