The Galileo Navigation Signals are transmitted in four frequency bands (E5a, E5b, E6 and E1) providing a wide bandwith for the transmission of the Galileo signals.
The Galileo frequency bands have been selected in the allocated spectrum for Radio Navigation Satellite Services (RNSS) and in addition to that, E5a, E5b and E1 bands are included in the allocated spectrum for Aeronautical Radio Navigation Services (ARNS), employed by Civil-Aviation users, and allowing dedicated safety-critical applications.
Galileo carrier frequencies and bandwith are shown in the table below. The names of the Galileo signals are the same than the corresponding carrier frequencies. Note that E5a and E5b signals are part of the E5 signal in its full bandwidth.
