The future of GNSS: Galileo + GPS

The following figures show a simulation of the improvement in positioning accuracy (over 95% of time)
brought by the use of EGNOS and GALILEO.

Figure 1: Mean horizontal positioning accuracy (95%) achieved through the GPS constellation alone (in m)

Figure 2:  Mean horizontal positioning accuracy (95%) achieved through the GPS constellation augmented by EGNOS (in m)

Figure 3:  Mean horizontal positioning accuracy (95%) achieved through the use of GPS, EGNOS and GALILEO (in m)
