- Intermernet 1mo agoWeirdly enough, I'm working on a similar system for position tracking in canyons. It's hybrid, uses a combination of Kalman filters, particle filters and GPS (EDIT: and LIDAR based DEM) and is based on the obvious (in hindsight) realisation that the view of the sky to get an accurate gps fix is inversely proportional to the constraints of the terrain. If you have a low field of view of the sky, you can use sensor data to constrain your likely position. I should have hardware samples for testing in the next month or so. Hopefully my theory stands up!
- dwa3592 1mo agoLove it. Position tracking in canyons is a much needed use case. Is there a link where I can follow your progress?
- Intermernet 1mo agoNot yet. I currently have one private repo with everything in it (hardware design, firmware, experiments, notes etc.). Want to clean it up before I release anything.
- dwa3592 1mo agoNice! Good luck.
