Hi. I'm a newbie in this list, but I'm a telecom engineer and have experience in signal "soft decoding".

I just bought a GPS unit a few weeks ago and I'm very curious about the protocol. I know the basics, but I would like to know more about the PRN codes used (Gold codes) and the format of ephemerids and almanac transmissions. Basically to know enough to soft decode the satelites' signals.

I just subscribed to this mailing list and seems that people here have that kind of information. Could you possibly point me to online "deep" docs about that subject?. I'm more interested in docs that source code, BTW.

Thanks in advance for your time and attention.
