Thanks, that's a bummer.  Well, if it's an easy fix and you get around to it, I'd appreciate it.  I thought it was clever to design it so that it could go 400°, allows me to fly a little behind myself with worrying about having to swing around.  The pan servo is fairly slow so I wanted to avoid that.  Takes something like 3-5 seconds to pan around.

in my experiance it doesnt realy matter, as 90 percent of the time the tracker will be at or close to 90 degrees tilt, so spinning around realy has no noticable effect.

@R Lefebvre,

One soultion would be to simply use a diversity setup with one directional and on e omni antenna. Since transit time is only really a problem at close range the omni would be well within it's range to provide a strong signal, and when at sufficient distance the speed of the pan is more than sufficient to provide excellent range with a directional antenna. It's a bit more expensive to setup this way but way more reliable.

I'm also using a diversity setup and it works really well.

Michael, you must be flying in close to have such a high tilt angle? I am often flying at long distances in auto mode, with more horizontal angles, so it is important not to have it rotate back when it hits pan limits. It's usually easy to avoid if you orient it correctly on the ground first. Long range missions don't tend to require much pan (<180 degrees) as you are flying in one general direction.

I've tried to set this up with the Micro Maestro and while I can get the Pololu command center to move the pan/tilt servo's on the tracker.  Using the same comm port in the MP nothing happens, I can move the trim sliders and the servo's don't respond.

 

Comm port and baud are the same settings, but in MP the communications led on the Maestro just does one quick flash and goes back solid anytime I click the connect button.

 

In the Pololu software it rapidly flickers and of course the servo's work as I move the sliders there.  I'm using MP 1.2.35 mav 1.0

 

Any suggestions that might help?  It appears to me that MP isn't establishing comms with the Maestro.  I've tried all the baud rates on the drop down menu, none of them do more than that single quick flash when I press connect.

Well I finally got the Micro to respond sorta, had to set up the Maestro in Pololu's Controller to default to the USB port for comms.  Now though the pan servo operates like expected, but the tilt servo goes to the pwm limit and stops.

 

Looking at the settings in Pololu's control software, the tilt servo is going to 2000 pwm pulse width.  Using the MP antenna tracker, I can use the trims and where ever I leave them, I can go to Pololu's control software and the pan servo shows the setting from MP but the tilt servo is always at the max of 2000.

 

I can use the Pololu controller and move the tilt servo, so it isn't the servo or the Maestro.  Has anyone gotten the Micro Maestro to work with the antenna tracker?  If you have, care to share some settings or things to check?

hey guys question i have the micro maestro 6 channel 3 dradio and i use the arduplane gs

problem i move my servos from the config of maestro but not from the mission planner.

the antenna tracket and micro maestro are connect but dont receive any command from the mp
any ideas please because i try many config and nothing happens or maybe you have the right way to setup thanks guys and sorry for the bad englisch

Marcus,

In Maestro config software I had to set the serial config to USB Dual port.

I've still not gotten it to track with any accuracy.
