(b) The second step is “Records Tilt”. In this step, you should collect tilt points in 4
direction, and in every direction you should collect 10 tilt points. There are some
conditions to do this step.
① The pole should set on the same points during all of the steps when you are
collecting tilt points.
② The tilt angle should be between 25° to 35°. This angle will show in the
controller screen, so you can check it directly.
③ When you do this step, the controller should be fixed solution.
④ Collect tilt points in 4 directions, East, South, West and North. It also has a
angle to show the direction. 90° is for East, 180° is for South, 270° is for West, 0° is for
North. When you do this step, the angle should be closed to those angles. In each
direction, the receiver should be stable station.
