Abstract:

The U. S. Army Corps of Engineers has been developing a GPS carrier phase based positioning system for hydrographic surveying and dredging since 1988. This system provides real-time three dimensional positions with horizontal and vertical accuracies better than one decimeter over ranges up to 20 kilometers from a single reference station without static initialization. The project has passed from concept development through feasibility studies, system analysis, resolution of carrier ambiguities on-the-fly OTF, to final system integration. The real-time testing of the system began in March of 1993 and public demonstrations of the system began in October, 1993. Testing of the system has been performed under varying operating conditions to evaluate the limits of OTF ambiguity resolution for precisely positioning moving platforms. Tests have shown that this system is capable of 1-3 centimeters in all three dimensions. This paper will the results of the testing to date and briefly describe the OTF system.
