Abstract:

The TI4100 receiver collects data from the NAVSTAR Global Positioning System of Satellites GPS. The Defense Mapping Agency DMA and a number of other organizations have utilized these receivers to exploit GPS for a variety of geodetic applications. This report provides a comprehensive set of operational procedures and guidelines for the estimation of geodetic points positions absolute positions from data collected with the TI4100 receiver. The specific algorithms which are addressed here have been developed into efficient, portable FORTRAN 77 programs which are known as STARPREP and GASP. The name STARPREP is a contraction for GEOSTAR PREProcessor while GASP is an acronym for Geodetic Absolute Sequential Positioning program. These two programs are designed to work in concert to exploit GPS data for geodetic point positioning applications. A few other utility programs are also addressed which perform functions such as data transfer, data screening and data analysis. A set of minimum observation requirements are specified such that a geodetic point positioning survey can be planned and conducted efficiently. This report does not address the use of GPS data which has been subject to Selective Availability SA or Anti-Spoofing AS. This report will be updated when guidelines and standard operating procedures have been established for such data. JHD
