The Simple Physical Model

The simple physical model makes some assumptions about the Telescope moving.

• Pitch can be determined by the relative height difference in front and back wheels on the right hand A-frame and that the telescope Pitches around the front or back end of each A-frame.
• Roll can be determined by the difference in height between the two A frames, and that the Telescope Rolls around one or the other end of the elevation axis.
• That the Telescope yaws around the centre of the elevation axis, and that the yaw is defined by the difference in pitch between A-frames.

These assumptions can be applied to the Model of the track Surface to obtain the roll pitch and yaw corrections for each azimuth.
