Table 1[1] presents an order of magnitude of the 3-D position/time errors achieved with different types of receivers, both for Standard Positioning Service (SPS) and Precise Positioning Service (PPS) using legacy GPS. Note that this table is valid for GPS only and it is provided here for illustrative purposes[2].


Table 1: Comparative 95% three-dimensional position/time errors across various receivers.
  SPS PPS
  Best Location Median Location Worst Location Best Location Median Location Worst Location
Handhelp (best 4-SV solution) 16m 32m 72m 10m 30m 71m
Handhelp (AIV solution) 11m 25m 54m 8m 23m 53m
Mobile (land/marine vehicle) 7m 23m 53m N/A N/A N/A
Aviation receiver (AIV, RAIM, tightly coupled with INS) 7m 24m 55m 4m 5m 6m
Survey receiver (dual-frequency, real-time performance) 3m 4m 5m 3m 4m 5m
Aviation receiver dynamic time transfer performance 14ns 45ns 105ns 12ns 13ns 14ns
Time transfer receiver static time transfer performance 10ns 19ns 35ns 10ns 10ns 11ns
