Yes, that was the original intention, but actual use proved otherwise. If you have a clock and correlators that are capable of using the P code, they'll do just as well on the C/A code. The key is how well you can align on the transitions between chips, not how far apart they are. -- Dave Tweed -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
