Mellow Bullseye HFDF location demonstration. This repository contains python ports of old HFDF fix (location estimating) routines and some applications which demonstrate their use. Of course, the world has long since moved away from HF radio, and the stations which used to take these observations have been closed since the mid 1990s.
How to determine transmitter location on a global scale using HF radio? One approach would be to create a collection of stations scattered around the globe which could be tasked to monitor a radio frequency and return an observed bearing (and bearing quality). Transmitter location could be estimated using the observed bearings.
- autofix.py consumes files from artifact_in and writes updated files to artifact_out.
- bullseye.py provides a UI to interactivly processs artifacts
- generator.py creates artifacts for testing
- POSLOC
- locations in decimal degrees (no DMS) +North, +East
- bearings are always positive, clockwise from true north
