I wanted to dabble into setting up an antenna tracker. Got myself the ServoCity Tube servos, for Pan and Tilt. Assembled it all with a Polulu Maestro and got the interface working. Followed the article here :
Few things I couldnt figure out and would be glad if someone can point me in the correct direction:
-- Any way I can set a minimum radiius for the Antenna Tracking to start working ? Dont want the tracker to go round and round when I am flying close by or doing passes around me.
-- For the Tilt servo, I have a 180 degree servo travel. The article above says that the neutral should be set facing 45degrees .. In that case though I cannot utilize the full 180 degree travel . Can only get 90 at the most. So my question here is, can the tilt center be set to 0 degrees ie facing straight up and 90 tilt on either side ?
I think thats most of it for now . Would appreciate some help.
You will need to make sure all settings in mission planner under "Antenna Tracker" are correct. Also verify that you have selected the correct port and make sure baud rate is 9600.
I prefer using Maestro and Mission planner as I have a dedicated ground station for my realtime HD video feed.. Saved me from having to deal with the ardustation, costs, and setup.. Seems to be a little on the glitchy side regardless of setup. I get accurate tracking about 40% of the time.. Still getting the feel for setup, so i'm sure this will improve over time.
My antenna tracker (to the right), houses the maestro and my 5.8ghz wireless bridge, I run ethernet to my groundstation and USB from maestro to my usb hub and it's all setup and ready to go. Only have to set tracker location under mission planner and I'm good to go.
Did you say HD or is that 640x400 SD ?
HD - 720p - full stream with about 150-200ms of lag which is good enough for me! the device in the center is the wireless transmitter and controller for my Sony HD goggles. Picture is simply breathtaking; my fat shark dom’s and the standard HD signal don’t hold a candle to the video quality I get with my HD setup..
Here’s a screen capture from my last field test; capture is only running at 15fps and 90% quality, but you’ll get the picture… My last test I had full HD feed out to about 450 meters before I had a radio failsafe that sent the quad home…
Is there anything I need to do to get the tilt working, like setting a home altitude or something? I can control the tilt servo with the pololu controller program and with Mission Planner, but when I fly the pan servo works find but the tilt servo moves to -45 degrees and stays there.
