Article Headlines
  • General Atomics Aeronautical Systems completed the first Beyond Line of Sight (BLOS) High Frequency (HF) Command and Control (C2) demonstration for an Unmanned Aircraft System
  • The HF C2 capability does not require a Satellite Communications (SATCOM) link and is capable of providing BLOS connectivity up to 8,000 miles, depending on transmit power and link geometry
  • For the demo, GA-ASI integrated the U.S. Government’s Collaborative Operations in Denied Environment (CODE) autonomy software into the Open Operational Flight Profile (OFP) of an MQ-9A Block 5 Remotely Piloted Aircraft (RPA) and flew the MQ-9 using improved diagonal tails with conformal HF antennas incorporated into the leading edges
  • GA-ASI’s MQ-9 housed a FlexRadio Systems’ FLEX-6600 HF software-defined radio and associated hardware to translate and execute an autonomous mission plan. GA-ASI created a specialized HF software adapter to manage the unique latency and throughput constraints of the HF waveform to demonstrate BLOS command and control of the RPA
  • The demonstration was flown out of Laguna Army Airfield / Yuma Proving Grounds on Dec. 16, 2020. The MQ-9 was commanded from Austin, Texas approximately 1,000 miles away over an HF C2 link. This capability enables an operator to task the MQ-9 without needing SATCOM, providing a means to operate in SATCOM-denied, contested environments
