Re: Balloon project / APRS based antenna control?



Hi,

It should be fairly straightforward as you know the position and 
velocity vectors of both the device and observer.

You could use a modified version of something like 'Predict' to do the 
az-el calculation and use it's serial drivers for something like a G5500.
