Seamless surveying system
First Claim
1. A seamless surveying system with complementary data sources comprising:
- a master rover unit coupled to a virtual reference station and adapted to receive SATPS data, said master rover also being adapted to acquire non-SATPS position determination data via a non-SATPS survey method;
a programmable data processor coupled to said master rover unit, said programmable data processor being capable of combining said SATPS data with said non-SATPS data acquired via a non-SATPS method by applying a weighting function to said SATPS data and to said non-SATPS position determination data, and also being capable of determining a position from the combined data.

Abstract
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.

14. A computer readable medium containing executable instructions which, when executed in a processing system, causes the system to perform the steps for determining a position from complementary data comprising:
-
accepting SATPS position determination data from a virtual reference station;
accepting non-SATPS position determination data obtained from a non-SATPS survey method;
combining said SATPS position determination data with said non-SATPS position determination data by applying a weighting function to said SATPS position determination data and said non-SATPS position determination data; and
,determining a position from the combined data. - View Dependent Claims (15, 16, 17, 18, 19, 20)
