have some OJ, Jimp + read up;

Chip rate for C/A is 1.023 10^6, chip rate for P code is 10.23 10^6 
(chip rate is SS)

The GPS signal is said to have a spread spectrum because of its 
intentionally increased bandwidth. In other words the overall bandwidth 
of the GPS signal is much wider than the bandwidth of the information it 
is carrying. In other words while L1 is centered on 1575.42 MHz, L2 on 
1227.60 MHz and L5 on 1176.45 MHz but the width of these signals takes 
up a good deal of space on each side of these frequencies than might be 
expected. For example, the C/A code signal is spread over a width of 
2.046 MHz or so, the P(Y) code signal is spread over a width about 20.46 
MHz on L1 and the coming L1C signal will be spread over 4.092 MHz as 
shown in the image above.

Because GPS is SS, you get more RF system gain, you can pick it up under 
an automobile, or a cellphone with very poor antenna.

Look at Iridium, global sattilite com system, it is not SS, and coverage 
does not reach as far.
