AEHF, 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
Delivery of the uplink phased array high-efficiency converter (UHEC) means that testing of the uplink phased array subsystem can begin later this year. Each UHEC operates the uplink phased array antennas on each payload and their "first-ever" technologies developed specifically for AEHF, said
The UHEC delivery paved the way for payload integration and testing, which began
"Delivery of the UHEC was ahead of schedule as we applied lessons learned from the early delivery of the first three AEHF payloads we built," Linsky said. "We plan to follow this first early unit delivery with more early deliveries to achieve the government's affordability expectations."
When completed, the fully integrated payload module will be shipped to
Uplink phased array antennas, which receive signals from ground terminals, direct radio frequency beams electronically rather than by moving reflectors mechanically. This allows one array to do the job of many reflectors, giving the flexibility to point on demand in fractions of a second, greatly improving warfighter access. It is also the first phased array for space application that operates at 44GHz.
The highly directional antenna additionally reduces the possibility of jamming and intercept by enemies, ensuring secure, reliable communications between command and control units wherever they operate.
