finally did it!! live video transmission between two esp32 with PCB antenna at 1000m distance! 640x480 and >20fps. we have a protocol above UDP packets. It allows sending large amount of data over small packets without having to use ACK and retransmits (not FEC).

Snowfalls from this week in Switzerland seen from 100'000ft. The meteoglider keeps returning radiosondes to launch site no matter the season.

600'000 radiosondes ($100M) are lost in nature each year after being used for only 2h. The Meteoglider returns to home after each flight to be reused.. it has been tested by national weather services in Switzerland, France, Spain and Denmark. NOAA it's your turn!

I made a 240g glider that returns to home from the stratosphere, it took me 5 years.

the white dot in the upper left corner at 1:30? that's two others Meteogliders about to fly back home too😊 Returning 2 x Vaisala RS41 and 1 x Meteomodem M20.

at Meteomatics we dare mighty things* *249g Meteoglider (including 4K camera) releasing at 30'000m before returning to weather balloon launch site with precious weather sensors. Making them reusable.

weekend project: get 3D position from trilateration between three LoRa ground stations! GNSS (green) vs LoRa ToF trilateration (red), as computed onboard.

live image transmission between two esp32 with PCB antenna from ~400m distance..needs some improvement before reaching 1km!
