Warfighters depend on high-frequency (HF) radio transmissions to operate military systems across the space, air, ground and maritime domains. Current understanding of how HF waves propagate through the electromagnetically noisy ionosphere typically depends on ground-based methods. To more accurately understand HF propagation in space requires scientific measurements taken from within the ionosphere itself. DARPA’s new […]
