Navigation System Precision Analyses

The Navigation System Precision (NSP) Analyses return the HNSP, VNSP, ONSP and TNSP over an area. Results are presented as statistics on the maximum, minimum, average and 95-percentile NSP for user receivers located in the area determined by the end-user.

This map presents the worst Horizontal Accuracy (1 sigma confidence level) expected for a Galileo Receiver with Open Service Dual Frequency L1E5b and under a Rural Vehicle environment.

The Availability of NSP can also be computed over an area for the nominal satellite constellation or including satellite failures.
