Teams can lose the satellite for hours at a time.
HF stays up. ASX makes it carry more.
As satellites become contested, HF is moving back up the comms plan. It's resilient, but it was never built for much data.
ASX changes that, on radios already in the field. We don't replace SATCOM; we make the fallback far stronger.
As SATCOM becomes contested, HF is climbing back up this plan. ASX elevates HF for the climb, whether that means carrying it toward Alternate or making it perform better where it already sits.
Throughput
Move HF from messaging toward imagery and richer command-and-control, in the same narrow channel, when nothing else is available.
Low emissions signature
Less transmit power and shorter time on air, a smaller emission window for units whose survival depends on staying unseen.
Battery & SWaP
Less required transmit power flows almost directly to battery life, a real win where the manpack and its batteries are carried on someone's back.
Not a new terminal. Not more spectrum. Not a rip-and-replace.
The usual way to get more out of HF is more spectrum and new hardware, a bigger footprint to detect and a procurement cycle to fund.
ASX loads onto the existing hardware already in the field, and gets its gain in the same bandwidth. It makes the incumbent radios better rather than asking anyone to replace them.
