I found another Gimbal for this application:

I was unhappy with the amount of GPS āwanderā I was getting with a normal M8N GPS using GPS/SBAS/GLONASS. So I installed a second GPS to blend in Beidu and Galileo, which it improved quite a bit. However, the setting that made a major difference was GPS_NAVFILTER.
A summary of the setting is available here: https://discuss.ardupilot.org/uploads/short-url/jBfmt7aXvG31ldCiktTQsNG0Jfh.pdf.
Iād strongly recommend setting GPS_NAVFILTER to 2 (stationary) if youāre having any problems with GPS wander.
This is excellent! thanks! I have a problem on arming where an error pops up āInternalError iomcu_resetā and the tracker then freezes. has anyone else come across this? and how did you fix it?
I wish there was a way to simply change the default direction. From north to the direction of the mission , a regular 180/90 degree servos / Maestro would be good enough for most of the missions that are south and east/ west bound ā¦ super simple to setup and pretty accurate tooā¦ is it so difficult to do?
hiā¦ i have same proplem .
i try to build tracker pixhawk 2.4.8 i make allā¦ all calibrations ok. i follow all tips .
but last when i make arm AT , its give me Ä°nternalError 0x1000 . i dont find any solutions 
did you find it ?
someone ?

I experienced the same problem as Lars_Meadoworth when trying to test my tracker with simulator with the tracker connected to Mission Planner via USB cable;
when I set the Mavlink output to the trackers COM and baud it gives me the message āif using com0com please rename the ports to COM??ā
ive ran into the same issue, what ill do is set the tracker to auto mode, then disconnect it leaving the com port open. That allows the serial forwarding to function and ill get the long audible tone, however even though I get the tone indicating track, the tracker stays in what looks like a scan function, looking left and right by a few degrees for about a minute before tilting all the way up, rotating about 30 degrees before tilting down and starting its scan again
Thank you for your efforts on this tracker.
I have been using arduplane for over seven years and have just now tried antenna tracker.
Honestly Iām frustrated by this tool as Iāve setup the platform including continuous servo for yaw and even established a tracking between simulator and at. I can see the tracker follow the sim plane but no luck with the yaw tracking.
I have recalibrated compasses three times and think I may have an issue with how arduplane is using my compasses. I have disabled all but the one in pixracer.
Would be happy to share param files as Iād like to get this working. Iām doing more work that requires a high quality realtime video link. Iād like to understand what Iām doing wrong, as I think Iāve setup this config as it should be.
EDIT: Good news! I decided to get my full setup together, mount the Pixracer and GPS and then restore default settings within the AT. Top line - this worked. Here are a few ah-ha moments:
- Tracking works with the simulation rig 100% of the time. Thank you for this guidance, and it is clear to me what AT is doing both for positional tracking as well as simulated RTK on the simulation setup. This also told me the actual guts of the code were working, as I noticed both position of the AT and its relative tracking of the simulated aircraft were working. The issue must have been with he servos.
- Use continuous rotation servos. Default settings are NOT set for this, but that seems to be okay. After I reset parameters, I started first with Yaw, and noticed that the AT did a fine job tracking the simulated plane in a loiter pattern. The only caution is when the loiter radius is behind the AT - be careful on how wires can get quickly tangled as the servo will rotate around itself quickly.
- AHRS and Orientation. I know this is mentioned early in the these posts, but will highly recommend you orient the flight controller (in my case, a small pixracer) AND GPS and ensure that both the artificial horizon AND orientation in parameters match. This may take a few reboots to get there. On my fixed wings, Iāve had a few issues with odd AHRS settings (roll, pitch and combinations) but once they are set, magic happens.
- Donāt be afraid to do the compass calibration a few times. It is crucial to have green, and have learned this the hard way on my fixed wings.
Thanks again for the work on this, and look forward now to my rig in the field for use with my RubyFPV setup.

Still happy with your antenna tracker ? I am working also on it
Regards
I used it a few times before it got cold and have not tried again yet this winter. I will be out tomorrow to do some tests and will let you know. Biggest challenge for me is the MAVLINK radio connections - two of them - and being able to manage my plane through QGroundcontrol with it observing a second radio.
