Abstract:
1. A system, comprising: a first base unit including a first vertical laser transmitter configured to emit a first vertical laser plane, where the first vertical laser transmitter is capable of being rotated about a substantially vertical rotational axis to position the first vertical plane at a first azimuth angle with respect to a first null angular position; a second base unit including: where the first base unit and the second base unit are configured to translate between a three dimensional coordinate and a first azimuth angle, a second azimuth angle, and a pitch angle that specify positions of the first vertical laser transmitter, the second vertical laser transmitter, and the horizontal laser transmitter, respectively, that will cause the first vertical laser plane, the second vertical laser plane, and the horizontal laser plane to intersect at a position that corresponds to the three dimensional coordinate.
