What is the frequency and behavior of the C/A code?

Explanation:
The C/A code is GPS’s civilian spread-spectrum code: a 1023-chip pseudo-random sequence that repeats every 1 millisecond. It’s transmitted at a rate of 1.023 megachips per second, so each 1 ms frame contains 1023 chips and the same sequence repeats each millisecond. Each satellite uses a unique C/A code (PRN) to distinguish its signal from others, which is why you can separate signals from different satellites even though they share the same carrier frequency.
