Advanced EHF, the next generation of protected military communications satellites, provides vastly improved global, survivable, highly secure, protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms. The system also serves international partners including
"The complexity of this payload provides users with literally millions of options for countering various enemy electronic, cyber and physical threats," said
Each AEHF payload contains 10 mechanically steered antennas as part of a subsystem that processes gimbal-pointing commands for precision pointing. The GCU operates two crosslink antennas, two nulling antennas and six gimbaled dish antennas, all of which have greatly increased pointing accuracy and improved reliability.
"The benefit to warfighters is high reliability and high data rate broadband communications in remote regions not covered by fixed RF antenna assets," Linsky said.
The AEHF payload provides and controls all EHF uplink, Super High Frequency downlink and crosslink functions, beam forming, on-board nulling, signal processing, and time and frequency control for low, medium and extended data rate operation.
The company has provided sophisticated and robust protected satellite communications payloads with increasing, highly secure connectivity to U.S. military forces for nearly 30 years. As the only company with this capability,
