DARPA seeks ionospheric insights to improve communication across domains
The Defense Advanced Research Projects Agency’s (DARPA’s) new Ouija program aims to use sensors on low-orbiting satellites to provide new insights into high-frequency (HF) radio wave propagation in the ionosphere, which spans the upper edges of the Earth’s atmosphere to the lower regions of space. Warfighters depend on HF radio transmissions to operate military systems across the space, air, ground, and maritime domains. Current understanding of how HF waves propagate typically depends on ground-based methods. The new program seeks to quantify the space HF noise environment and improve characterization of the ionosphere to support warfighter capabilities through two technical areas, outlined in separate solicitations. A Proposers Day is being held on May 4 in Arlington, VA; participants must register by April 29. For details and to register visit: https://sam.gov/opp/12011140279042b9957fd23c133ea97c/view
