"Terry, The time that the winch servo use to invert rotation is very small, when we are conducting  our model that 360 rotation is almost negligible, a majority of times its unnoticed in the video feed. Check the video…"

"This is quite an interesting idea.. simple and useful.. To follow-on from <jalves> comment - has the option of adding a second antenna and switching to it so that the rotation time back onto target is reduced significantly ? Also is the reason…"

"ideally, the AT should maintain the direction (what it does now, but have to improve the solution implemented). BUT if the video is fuzzy, you are in the limits of the video link then you should do a quick 180degrees turn and return to home…"

"I think that this is great work. My only concern is that the tracker is essentially dependent on the same signal as the video feed. What happens when you drop video when you are a long way out with a high gain antenna?"

Open Source Antenna Tracker - OpenDiyAT

Hello to all, I used a part of the Ardupilot legacy software plus code from Melih Karakelle and from Dennis Frie and "build" around an Open DIY Antenna Tracker - OpenDiyAT.It needs only sentences from a gps receiver unit (gprmc and gpgga) and it sends the telemetry to the ground using the audio link of our video transmitter.It is now in  a very reliable form, and it has still a good development base.With some work, we can increase the telemetry data to send to the ground base.I publish the code…See More

"Didier, Do you see some "jittery" from the servos when using DragonLink and Stabilize mode (or FBW, RTL)? Or Are the servos stable and calm when in normal, stabilize and/or FBW/RTL using the DL and Arduplane/APM?"

ArduIMU/Ap test platform ready!!

Hello all,



Developers of this combined project, Thanks!



Ugly and dirty, the system is ready to roll tomorrow, the bench tests all went well, although I think that the elevator amplitude (gain) isn't enough when in stabilize, which probably will happen also with RTL mode.



More to come, tomorrow.…
