Seamless surveying system

摘要

A survey system and method for determining the best source of position data for a particular application. The system includes both a satellite positioning system (SATPS) and a non-SATPS unit for obtaining position data. 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. Data is collected using both the SATPS and non-SATPS methods to obtain a master data set. Data is selected and/or combined from the master data set to produce the data subset required for position determination. The basic SATPS method may also be augmented by the use of one or more reference stations at known locations.
