"Did you have any success with this?  I am working the same issue."

"Have a look here here"

"You need a gps!    I've only worked with the MediaTek purchased from the diydrones store but this GPS at least returns the longitute and latitude in centimeters.  So at a high level all you need to do is have a preset…"

"IBCrazy on RCGroups has created an antenna tracker that uses several antennas, one recevier and 2 RSSI modules... It doesn't need the telemetry data it uses RSSI to track the plane. Also, my GCS is going to start outputting control messages and…"

"Eagle Tree has a neat system.   The airborne GPS data is encoded into the video in a part of the signal called the vertical interval.  This area is normally used for closed caption etc.  There is heaps of room for the data.  The…"

"I've read about using the GPS data to achieve antenna tracking. But doesn't that mean you need a data link to pass down the GPS position to establish the tracking? So it sounds like you need 2 antenna systems, one high gain which requires…"

"Would you guys consider video tracking the UAV with a telescope and piggyback the antenna on the telescope? That way you can use a directional antenna for the telemetry data link too and it may in theory increase the operational range of your UAV…"

"There are also other ways to do this. Some video tx/rx can send it down. this will require more parts and weight on the aircraft though. check out ezosd or ezuhf i think one of those EZ things will also include antenna tracking. I believe it's…"

"Basicaly look at the ardustation code, it has some information about antenna tracking. But here is a simple way to get started You know the approx 3D position of ur plane as it has GPS on it, When you startup you record the 3D position of ur…"

"This is something I have also been researching... It would be nice to hear from the wider community if there are any ingenius ways to get this to work :) Thanks"

"ok, thanks for your help"

"Not sure if I've still got it, been a long time since I did that. But its just a matter of opening up a serial port and sending the appropriate commands as per the VISCA protocol standard. Do a google search, and if you don't have any…"

"do you think you could at all send me the vb.net source?"
