The pan and tilt platform will hold the high gain yagi used for receiving the HAB signal.

I’ve just got a small, simple platform for now to test with and will upgrade it once everything is working well. It’s driven with 2 hobby servos direct from the Arduino. One minor drawback is that a standard hobby servo only has a round 90 degrees of movement. That is fine for the tilt control but no good for the pan control so I will have to try and source a servo capable of 360 degree rotation that provides position feedback or maybe build a 4:1 drive system for a standard servo.

I wrote some test code for the Arduino to try it out. It takes input from the serial connection and controls the servos on command.
