Antenna tracker prototype up and running

Posted by UFO-MAN on August 11, 2009 at 12:30pm

I got the telemetry and videolink azimut / elevation antenna tracker prototype up and running the other day. Here is a video of it (without antennas) when it receives ASCII commands from the test software running on my lab PC.

Preliminary specs:
=================

720 degree azimut rotation range
>110 degree elevation rotation range
Relatively high torque
Ball bearings on shafts
Tracking controller programmable in C (Arduino based)
Commands to tracking controller can be sent via serial link from the ground control computer
ASCII based command protocol.

    The cables are run inside the axle so the control cables are non problematic. The coax cables are looped. The controller will have logic that prevents cable jamming.

    Jordi, care to elaborate on yoru project?

    Do you have some logic to allow the antenna cable not to get twisted if rotated in the same direction all the time? Or a controller that is smartly tracks the turns in the cable?
    Just my 2 cents

    Hi Jordi. The mechanics is servo city. The code is my own. I am building something modular that can accept commands from several sources.

    ServoCity right? But my Tilt and pan is the medium size.
