5) About PAN TILT mechanics

GhettoStation handles any type of pan/tilt mechanic based on non continuous servos (any normal r/c servos ).

To cover 360° with your antenna you can do booth ways:

• 360° Pan with a 90°(or more) Tilt
• 180° Pan with 180° Tilt

You also totally can have a tracker limited to 180° rotation if you don't plan to fly far behind you. Then only a 180° pan with 90°(or more) tilt is sufficient. GS will always adjust itself according to its mechanic capacity.

I would say 180°/180° system have many advantages:

• easier to build
• less mess with wire winding around
• generally can pan reverse faster than 360° pan( it only has to pan reverse 90°, while it also invert the tilt ). 360° pan have to pan reverse 180° an in general uses also reduction => slower

If you plan to attach lot of thing on the tilt axis (like video Rx & diversity behind the patch antenna) then having a tilt limited to 90° is in general more convenient. 360°/90° also has generally more torque on pan axis because of the reduction.

Here are the 2 GS I've built, one of each. You can compare.
