GLOBAL POSITIONING SYSTEM EXPLOITATION BY ODOT. FINAL REPORT

A new Department of Defense system of navigation satellites will become operational in the early part of the next decade. This system called NAVSTAR is currently in limited operation for development purposes. Because of the accurate nature of the satellite's clock and the accurate knowledge of its position in orbit, geodetic surveyors are able to exploit the NAVSTAR satellites for determining accurate positions relative to existing primary horizontal control monuments. The NAVSTAR satellites and associated support equipment when used in the positioning mode is termed the "Global Positioning System" (GPS). Using several GPS ground based receivers the surveyor can measure the position of a survey point to accuracies of two parts per million after only about one hour of observation time. This exceeds the accuracy of the Nation's primary network of horizontal control. The potential for use of GPS methods of geodetic survey by departments of transportation is evident. With this as an objective, the final report discusses the ODOT requirements for geodetic type surveys, the theory of GPS surveying in the translocation (relative) mode, current GPS receivers and applications of GPS aimed at meeting ODOT's requirements. The final report concludes with a series of recommendations for implementation of GPS within the ODOT.
