Clicking on the balloon in question says 21 GNSS svc used. Would satellites be able to track when low to the ground?
Would be cool to mod one with a longer lasting battery and release it back up on a windy day. I think I would like to add one to my collection of stuff. Will be watching the map more often.
The balloon has a GPS receiver to get its position (satellites do not receive a signal from the balloon). Even close to the ground or on the ground, it will receive the GPS signals and get its position that it will transmit on its own frequency. Releasing one or turning one back on with new batteries would be a legal issue. Some people have lowered the power and used a dummy load resistor for close range experiment. Check the map at 0000 UTC and 1200 UTC to see where the balloons are going that day-it will surprise you over time how much that changes. I have seen them go out of the same site in all directions over time due to the winds
