This report discusses the analysis of GPS measurement data gathered under the joint sponsorship of the Defense Mapping Agency (DMA) and the National Oceanic and Atmospheric Administration (NOAA). The DMA/NOAA data have been made available to TSC in support of the Coast Guard's interest in using Differenctial GPS for civil marine applications. Pseudorange measurments gathered simultaneously at effectiveness of Differential GPS in reducing system bias errors. The results obtained show a significant reduction in bias errors as a consequence of differential processing. Mean horizontal differential errors on the order of one par in 100,000 were noted over site separations ranging from 276 to 1, 591 kilometers.
Emerging transportation applications require positioning solutions with accuracy of a few centimeters. Current Global Navigation Satellite Systems (GN...
