Improved Ionosphere D-region Specification for High Frequency Propagation
Summary
The Navy Office of Naval Research seeks proposals to develop tools and techniques that improve characterization, specification, and forecasting of the ionospheric D‑region for high frequency (HF) and very low frequency (VLF) signal propagation. The effort aims to achieve finer temporal and spatial resolution and reduce electron density errors, enhancing operational models such as NIMO used for Navy space weather needs.
