Default Satellite Positioning sytem, another way

Over the years I have used different ways to move my antennas.
My current set up is using two rotators. One is a radio shack that is used for azimuth and the other is an alliance U100 that is used for elevation. A bracket was made to hold the U100 on top of the radio shack rotor.

But there are problems in the set up.
1-The U100 is easy to get out of alignment.
2-The rotors step gear is too long.

Resolutions I am looking at.
1-Digital inclination meter. These can be obtained at different hardware stores. These are called electronic spirit levels.
Remove the unit from the level.
Remove sensor from unit.
Mount sensor in water tight box and add cable connectors.
Mount sensor box on horizontal mast.
Sounds easy? I am going to try this and see what comes out.

2-By using the U100 the gear makes 1 revolution then sends a signal to the control box. By this time the antenna may have went past the spot you need to be at. You can modify the gear by adding another “finger”. This way it slows things down.

What I am looking to do is use a C-band dish actuator. These will move your antennas very slow. A simple control box can be constructed. Plus most of these work from 12 to 36 volts.

I will post pictures as my progress moves forward.
Here is a pick of the angle meter I will use in this process.
