Based on assessing needs (and nice-to-haves) from previous weather balloon flights, I have developed a balloon tracking and recovery web page. We can enter the balloon's call sign, burst detection altitude (as a fallback), and upload the flight forecast KML file. It then shows the balloon's beacons and path in real-time. People can also add themselves as chasers under the chasers tab. Chasers show up as red circles. You can click on an icon to see information about the chasers. The icons will update on an interval, but it will not show a path for chasers like it does for the balloon.
Here are the especially helpful parts. WX4BK has implemented a burst detection system on the Raspberry Pi that we fly. It datalogs once per second. When burst happens, we sometimes lose comms for a few minutes. The Pi logs the highest altitude (burst altitude) and location. When communication is reestablished, it sends a beacon saying that burst has happened, and exactly where it happened.
My page reads that beacon in real time, parses it, and uses my proven method of calculating the bearing and distance between predicted burst and predicted landing to identify the likely landing point and also draws a 3 mile search circle around it. No more switching between apps and tabs on the fly in our vehicles or out in the field (quite literally!). Just copy the coordinates, and we're off to the landing area.
You can check out the page here. You will only be able to add yourself as a chaser. If you don't see other data on the map, it's because I am still experimenting and working out some issues. For the tech savvy among you, yes, I know the admin password is not exactly secure. Please do not share it or point out where you can see it. It's really just light security so that people don't accidentally wipe out the prediction or balloon path in the middle of recovery.
Also for the tech savvy, if you would like to see the code behind this (and further develop it) check out my project on GitHub.
