USSOCOM HF Geolocation Algorithm Challenge

How do planes geolocate radio signals on the ground? This 2019 USSOCOM Geolocation challenge hoped to find an algorithm that could optimize the capability of a transmitter that develops and fields signals across the air, ground, and sea. The goal of the contest was to develop an algorithm that can determine the location of the transmitter. The contest had a prize of $27,500 split among the five winners and lasted one month.
