Having an alternative to GPS in mission critical systems is enough of a case to justify the existence of Galileo in the first place. Things like drones or self driving cars are not just about accuracy, but also reliability, and civilian GPS is not bulletproof (especially not in urban area). We're already seeing triple band GPS implementations with Galileo, GPS and GLONASS (the Russian alternative).
- UnoriginalGuy 10y agoWhile I agree with the principle in your point, does Galileo operate on a different enough set of frequencies to avoid interference that would knock out GPS?

- jhayward 10y agoThis is not correct. The primary civilian signal for both Galileo and GPS have the same frequency on L1, 1575.42 MHz. Their modulation schemes and encoding are coordinated to not interfere. [1] http://www.navipedia.net/index.php/GNSS_signal http://www.navipedia.net/index.php/GNSS_signal
