Weather balloons already have restrictions on weight to minimize the consequences of collisions. The issue is that even if you can add a transmitter and meet the weight requirements, it's currently not possible to legally broadcast ADS-B data from a weather balloon.
- Someone1234 1y agoThey would need to increase the weight requirements if they're to add ADSB. Current ADSB transponders weigh as much as the entire weather balloon's package. Then add on the pounds of weight for batteries.
- ggreer 1y agoThe uAvionix ping200X weighs 50 grams according to its datasheet.[1] With a 1.5W continuous power draw, a 60 gram lithium battery would power it for 8 hours, for a total of 110 grams. WindBorne balloons weigh 1.1kg at launch (including ballast), and the FAA limit for such balloons is 2kg. 1. https://uavionix.com/wp-content/uploads/dlm_uploads/2025/07/Ping200X-TSO-DataSheet-UAV-1002852-001-Rev-H.pdf https://uavionix.com/wp-content/uploads/dlm_uploads/2025/07/...
