2. Galileo Signal Characteristics
2.1. Frequency Plan
2.1.1. Frequency Bands
The Galileo navigation Signals are transmitted in the four frequency bands indicated
in Figure 2. These four frequency bands are the E5a, E5b, E6 and E1 bands. They
provide a wide bandwidth for the transmission of the Galileo Signals.
Figure 2. Galileo Frequency Plan
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.
2.1.2. Carrier Frequencies
Galileo carrier frequencies are shown in Table 1. 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.
Signal Carrier Frequency (MHz)
E1 1575.420
E6 1278.750
E5 1191.795
E5a 1176.450
E5b 1207.140
