What is L1 and L2 in GPS?

In the case of the original GPS design, two frequencies are utilized; one at 1575.42 MHz (10.23 MHz × 154) called L1; and a second at 1227.60 MHz (10.23 MHz × 120), called L2. The C/A code is transmitted on the L1 frequency as a 1.023 MHz signal using a bi-phase shift keying ( BPSK ) modulation technique.

What is the GPS L5 signal?

The GPS L5 (1176.45 MHz) signal is one of the new signals belonging to the GPS modernization plan. It is broadcast in a radio band reserved exclusively for aviation safety services and the signal is thought to be used in combination with L1 C/A to improve accuracy (via ionospheric correction) and robustness (via signal redundancy).

What is the p code for GPS L1 band?

GPS L1 Band. The P Code is the precision signal and is coded by the precision code. Moreover the Y-Code is used in place of the P-code whenever the Anti-Spoofing (A/S) mode of operation is activated as described in the ICDs 203, 224 and 225. The PRN P-code for SV number i is a ranging code, Pi (t), 7 days long at a chipping rate of 10.23 Mbps.

How are GPS carriers modulated on the L5 band?

The GPS carriers of the L5 band are modulated by two bit trains in phase quadrature: the L5 data channel and the L5 pilot channel. Moreover, two PRN ranging codes are transmitted on L5: the in-phase code (denoted as the I5-code) and the quadraphase code (denoted as the Q5-code).
