Performance Comparison of Candidate U.S. Coast Guard WADGPS Network Architectures

K. Tysen Mueller, Mike Biester, Peter V. W. Loomis

Abstract:	The authors have developed a WADGPS network performance simulation and used it to evahuue three candidate WADGPS network architectures. This performance simulation is a combined Monte Carlo and covaiance simulation. The GPS satellite geometries and user locations are Monte Carlo simulated while the GPS, reference station, and user errors are modeled using covariance error models. The three WADGPS architectures include a CONUS DGPS network that uses a state space (explicit) network filter to estimate the WADGPS network corrections. The other two architectures use two measurement domain (implicit) network filter models. One is the well-known Partial Derivative Algorithm by Loomis and the second is a new algorithm that is designated the Minimum variance Algorithm. Principal output from this simulation are the root-mean square navigation position error statistics for users incorporating the WADGPS network corrections.
