Description (last modified by valentt) (diff)

This guy came up with the same idea as I did in the past few days. Launch weather balloons with mesh routers and create a near space mesh network that covers the ground below.

I am planning to launch a weather balloon with a router this summer and here are the requirements I came up with regarding wifi.

Router with wlan slo firmware and nodewatcher equipped with:

  • 1-wire temperature and barometer sensors
  • USB camera
  • serial port GPS
  • directional (bi-quad) and omni antenna

The router would relay live video or image capture and other data via wifi back to earth, where a directional antenna or more would provide an uplink.

Such a setup should not cost more than 80€ and could therefore be launched in greater numbers.

Doing some maths:

  • such balloon can go up to 30km
  • assuming wifi links up to 50km are rather simply feasible (here we are talking clear line of sight and low noise)
  • the balloon can therefore be displaced about 40km, therefore 100km distances can be bridged this way. By putting it lower, this range can be extended, but is affected by winds.

If a control valve for gas exhaust is used, the balloon could be used multiple times.

By doing this single experiment, we can determine if such a platform can be constructed low cost, simply deployed and used for higher capacity data transfer, line video stream.

We could try to cooperate also with Herman Potočnik Noordung Memorial Centre Vitanje. I talked with them about this idea some time ago and they seemed interested. But we have never managed to discuss anything more.

Here they used Ubiquiti equipment to talk to near space balloon.
