The P code is the Precise code, The C/A code is the Civilian Access code. They're modulated onto carrier waves. For example, when you listen to a radio in your car and the announcer says you're listening to, let's say, 760 megahertz... well, of course, you're not listening to 760 megahertz.

- The C/A Code
The original GPS design contains two ranging codes: the coarse/acquisition (C/A) code, which is freely available to the public, and the restricted precision (P) code, usually reserved for military applications.
GPS is transmitting in the L2 band (1227.60 MHz) a modernized civil signal known as L2C designed specifically to meet commercial needs as it enables the development of dual-frequency solutions; together with the P(Y) Code and the M-Code.
As explained in GPS Services, under Anti-Spoofing (A/S) conditions, P-codes (P1, P2) are encrypted to (Y1, Y2) for non-authorised users. Nevertheless, many commercial receivers are able to provide P1, P2 measurements among the C1.
28 Ιουν 2024 · The P code and C code are two different codes used in the Global Positioning System (GPS) for different purposes. Here are the differences between the two: 1. What is the chip rate of C/A Code and P Code? The C/A-Code is transmitted at a chip rate of 1.023 megahertz, while the P-Code is transmitted at a chip rate of 10.23 megahertz.
Are the actual 1023 bit sequences for each of the 32 GPS satellites available to consumers? I found the IS GPS 200 but it doesn't list the entire sequences. Are verified sequences available for download anywhere online? I'm trying to validate my python CA PRN generator.
