: Can anyone tell me the frequency band the GPS system uses?

The L1 carrier frequency is 1575.42MHz (this is the "civilian use" signal
that carries both C/A code and P code information).  The bandwidth is
2.046MHz and spread spectrum modulation is used.  The L2 carrier is at
1227.60MHz and carries the P code (which is called Y code when encrypted,
which it is, a lot of the time).  You can find more information if you
follow sci.geo.satellite-nav newsgroup.  You can use a web search engine
(like to find web sites a lot more GPS related
