Greetings,
I am preparing to take advantage of the MP's antenna tracking ability and I am interested in what peoples experiences are with the two common controllers, Maestro and the Ardupilot legacy board. What are the Pros and Cons for each and why did you choose the board you did?
Also there are a few things that are unclear to me.
1) For those who are using Maestro, where did you get the source code for accepting input from the MP. Links for downloading source code would be appreciated.
2) What is the most recent version of the source code for the Ardutracker code? I have found the link in the wiki to version that reports it has been deprecated but I have found no other version available. That version is listed as ver 1.0, but I have seen posts where people make reference to a version 1.1. Links to downloading the most recent version would be appreciated.
Regards,
Nathaniel

did you think about this:
Maestro 6-channel USB servo controller bottom view shows tx and rx and vin and gnd
so i think we can use that to get the telemetry radio to convert it to wireless .
i have everything like your setup and i will start working on that and hope i will not burn my Maestro controller and i hope it will work.
let know what you think about it?
here are some pic of the Maestro and the TTL 3DRobotics 3DR Radio Telemetry Kit

Does anybody happen to have any ideas how it might be possible to have a "wireless" antenna tracker? I want to build a tracker tripod that can be positioned some distance from where I have my GCS/laptop set up.
I'm considering a few options such as using Ardustation or Ardudstation Mega. But I'm also wondering if it might be possible to do something using the tracking functions of MP. I already have the Pololu servo driver, but have no idea how it could be set up wirelessly. Some kind of wireless USB link between the laptop and the Pololu, but that seems messy. Either that or have the Pololu directly into the laptop, but feed it through a PPM Encoder, then to a 2.4GHz FrSky transmitter, with an Rx in the tracker, but that's pretty messy too...
just to throw this out there.
how common is the 180 + 180 design antenna tracker. ive always used the 360, 90. but just want to see how common the 180,180 is.
I'm not ready to get a tracker going yet, but it would be helpful when manually adjusting my antenna to know the exact azmuith to point it. Mission Planner must know this already, but where do I find it? I could simply attach a magnetic compass to the antenna and not have to guess which way to point it when it needs an adjustment.
Thank you
Hi All,
What APM version are you using (2.0 or 2.5)? Also are you using an external GPS, if so....which one? The reason I ask is because I'm using APM 2.0 with the internal GPS and the latency is slow on the tracker plus the plane is not exactly showing the correct location in the planner on MP while walking the plane around (30-60 meters away). So my plane setup seems to have some interference going on and I think it's the GPS, maybe the 3DR radio with my 433mhz RC transmitter, or all three. Any ideas or others having similar issues?
I'm about to try an external GPS, but just thought I would ask the community.

I'm close to being finished building my tracker, and have a question. The pan on my tracker is capable of travelling more than 360 degrees, not multi-turn, but it can probably do 400-450 degrees based on a PWM from 600-2500. Can this be accommodated in MP? Or is there a hard limit of 360° and 1000-2000 PWM? Hopefully not, because 1000-2000 only gets me about 300°.
I'm planning to use a Maestro if it matters.
I have both the Ardustation & the Maestro.
I had troubles with Ardunio compiler a while back so I bought a Maestro, and if I'm using a PC with MP then I will only use the Maestro. The Ardustion is a good stand alone device.
One thing I really like about using the Maestro is that the speed of the servo & the travel range can be set independently from the the MP, making the movement a little smoother & preventing servo over-travel.
I have not tried this with a 3DR radio , yet..
Looks like you have sorted out a solution. I am using the tracker primarily for my video rx. I used the ardustation for a long time and it worked well. The main downside is it only works with xbee, and you need two of them if you also want to have telemetry to a laptop. As with all the diydrones stuff, it's open source so you can add features as needed. I customized the flight data screen so I could see the key info I needed on the LCD screen.
Using an old ardupilot board is another option which I have not tried. It doesn't have the inbuilt LCD advantage of ArduStation, though.
I recently switched to the maestro method and it works well, also. Took a while to get right, but I like how it integrates with mission planner much better, and setup is also a bit easier. I am about to upgrade to the RFD900 long range radios, so the old ardustation would not have worked anymore.
The only downside of the maestro solution is that there is yet another cable (laptop USB to maestro) to manage and keep an eye on to avoid binding. The ardustation at least could be mounted on the moving part of the tracker frame.

OK So I have successfully built the AT using the Micro Maestro 6 channel micro-controller, connected it to the MP and am able to communicate with the AT for a full 365 degree pan and 110 degree tilt.
My only question now has to do setting up and pointing the AT. The basic instructions say to setup the AT pointing North and use the trim function to point the AT at the home location. The only problem with that is that my field is in a North-South orientation and the pilots location (and the AT) is on the west side of the runway. Therefore if I setup the AT pointing North and trim the AT to point at Home (East) I only have 90 degrees of travel to the South before the AT swivels CCW to the other end of the travel range to resume tracking at a bearing of 181 degrees.
Can I setup the AT somehow to enable equal travel North and South?

ardutracker should still work, as nothing has realy changed, but the maestro offers more features in my opinion.
