was the UAV transmitting altitude and Position back to the base station using something like Xbee communication?

like the tracking antenna

@jokam85 Until you burn out someone's retina. Better to use a Class 1 then Class 2 in this case. I am pretty sure they use radar location. Much safer and easier option.

[SirDonRoyale]

@nyehnyi Or radar location, using multi-frequency "echo" location technology.

in my thought. they track gps signal from plane then computer push the antenna to move to its position. quite simple but tricky.

@henhen7890 : Polarization. The whole point of the dish part behind the feed is to reflect the signals to the feed at the focal point (or the focal cloud, more realistically), but you don't necessarily want every signal that you pick up. If you know what kind of waves you are looking for (in this case probably horizontal) you can filter out the ones you don't want (vertical) and only bounce back the ones you do want (horizontal). Similar to polarized sunglasses, basically, it's a wave filter.

@hamishprogeria - I'd wager the antenna's location was surveyed off-camera. After that, the craft would transmit its own GPS position, allowing the base station to calculate the azimuth, elevation, and range. From there, your computer could use a formula or a look-up table to translate those vectors into servo signals. It's a very practical application!

@hamishprogeria You don't even know how GPS works.

[smoln1]

Do you have Eagle tree trackin system or something else?

Thanks for your aswer.

[hamishprogeria]

how does it find it?

GPS?
