James, It appears EC is now using GPS sondes, and the radiosonde_auto_rx software (which can be run on an RPi) should be able to decode positions if not the full telemetry stream. If they work like

Mark, Carvel is the closest upper air sounding station. Before we launched our first balloon, we went for a tour of the station and saw how they filled and launched their balloons. We based our first

James - not sure where you're located relative to any Environment Canada upper-air sites, but you could build a radiosonde ground station and chase those! 73 de Mark N9XTN

I would have arm wrestled him for the chance to go up. Do you think we can find a sponsor to pay for the balloons and hydrogen? I’m not wasting money on helium. I’ve watched a number of jumps

I was looking at the ARHAB page for clubs and organizations that do HAB. Evidently it is not up to date. I am moving to Missouri in the next few months to either the Sedalia or Lincoln MO area. I

What's your preferred programing language. I suspect their are Perl and Python one-liners that'll do that if you include the right library. Mike

Is this what you’re looking for? https://medium.com/javascript-in-plain-english/calculating-azimuth-distance-and-altitude-from-a-pair-of-gps-locations-36b4325d8ab0

geez 20+ years ago I had a .BAS program where if I put into it my lat/long/alt, and a second lat/long/alt it would spit out a az and el of where the balloon would be in my sky.

Don’t forget that they are easiest to see when the sun is at your back and they are therefore brightly illuminated by the sun. (If the sun is on the other side of the balloon it will likely be too

Looks like three were launched by Ravens this morning! Depending on where they go I may be able to see them. https://www.flightradar24.com/HBAL04/25366d23
