1. A 3D controlled paving apparatus, including:
- a slip form paving machine;
a location-determination device supported by the slip form paving machine and arranged to rotate around an axis in a generally horizontal plane, the location-determination device adapted to operate in conjunction with a fixed base station to determine geodetic information about the slip form paving machine at least twice during each revolution of the device around the axis; and
a machine controller adapted to control one or more 3D operational functions of the slip form paving machine based on the geodetic information.

Abstract
A construction system utilizing 3D control includes a fixed base station of known location; a self-propelled construction machine located in the general vicinity of the fixed base station; and a rotating mobile unit assembly mounted on the self-propelled construction machine and having a location-determination device arranged to rotate around an axis. The location-determination device is adapted to operate in conjunction with the fixed base station to determine geodetic information about the self-propelled construction machine.
