The U.S. Army Corps of Engineers initiated development of a prototype differential GPS positioning system for dredging and hydrographic surveying in 1988. This system is to provide real-time accuracies better than one decimeter over ranges up to 20 kilometers from a single reference station. A critical feature is to provide the positions in three dimensions to permit enhanced tidal datum determination. The initial stages of the work have been to perform concept development, feasibility studies, and system analyses. The project has recently concentrated on developing a robust technique to resolve ambiguities on-the-fly. Initial results reported in May 1991 are encouraging. Several experiments are currently being conducted to evaluate alternative resolution methods and to quantify operational constraints of the technology.
