GPS L1 1500MHz - 1600MHz Frequency
GPS L1 band: the central frequency is 1575.42mhz,range of 1500mhz to 1600mhz. The L1 band is mainly for civil use and contains two kinds of codes, one is called rough capture code (C/A) code, the other is called fine ranging code (P code). All the L1 signals on all 24 satellites use the same frequency but do not interfere with each other, as each is amplified by a PRN code covering the 2.046MHz band. After PRN code amplification, GPS signal can not only be distinguished from other signals, but also have anti-interference ability.Its anti-jamming capability is mainly that it is not easy to be interfered by signals of other frequency bands, but it will be shielded by professional GPS jammer.
