A: While GPS satellite faults have always been infrequent, they have become rarer in the past decade due to the maturity of the GPS constellation and its Operational Control Segment (OCS). Lessons learned from past GPS satellite failures have also aided the development of newer GNSS constellations such as the European Galileo.
