Single processed independent and trivial vectors in network analysis

Software for processing single vectors is often used to densify geodetic ne tworks based upon global positioning system (GPS) data. When operating more than two GPS receivers in the same survey session, the covariance informat ion among vectors is not readily available for the subsequent network analy sis. A procedure is suggested for regenerating full covariance information for the mathematically independent vectors using all single vectors. As opp osed to the approach of using all combinations of vectors, the suggested pr ocedure has the advantage of not introducing false reliability into the net work analysis.
