Abstract
A survey system and method for determining the best source of position data for a particular application. The system includes both an optical unit and a satellite positioning system (SATPS) unit for obtaining position data. The optical unit includes a theodolite and an electronic distance meter for determining the position of a rover unit. The SATPS unit includes a SATPS antenna and a SATPS receiver for receiving signals from satellites of the SATPS and a radio for coupling the received signals to the rover unit. The present invention automatically determines the best source of position data. The best source of position data is then used to calculate the position of the rover unit.
