Galileo begins service and consumer navigation becomes multi-GNSS

When Galileo Initial Services became available, users gained access to another global source of positioning, navigation and timing signals that was explicitly interoperable with GPS. This mattered because modern receivers increasingly stopped asking, 'Can I see enough GPS satellites?' and instead searched across several constellations. More visible satellites can improve availability and geometry, particularly in cities where buildings block large parts of the sky. In everyday devices, 'GPS' was becoming shorthand for a broader multi-GNSS positioning system.
