Table 2 Root mean square orbit errors in the along-track (A), cross-track (C), and radial (R) direction and the clock errors (T), total and orbit-only SISREs of Galileo and GPS IIF (RAFS) satellites (units: m)
From: Analysis of Galileo signal-in-space range error and positioning performance during 2015–2018
