HF (Compact, Mini and Micro)

The HF radar sounder is a compact ~2.5 kg system that operates at two frequency bands, 14-35 MHz. Mounted on the G1X this UAS has a 120 km range, 75 min endurance, 30 m/s cruise speed, and consumes ~4 L of fuel per flight. Recent work has demonstrated an ability to fly repeat tracks with ±10 m horizontal and ±3 m vertical accuracy, enabling precise construction of multipass arrays.
