This article breaks down the frequency bands used by Global Navigation Satellite Systems (GNSS) and the Global Positioning System (GPS). We’ll cover bands used by systems like GLONASS, Galileo, Compass/Beidou, IRNSS, as well as the specific frequencies used by GPS, including L1, L2, and L5.
GPS Frequency Bands (L1, L2, L5, QZSS)
The following table outlines the frequency bands used by GPS and the Quasi-Zenith Satellite System (QZSS).
