Could you elaborate on what you mean by seeing GPS L1. Does this me
acquisition, tracking, seeing bumps on an FFT, etc. I ask because I
am starting to build up algorithms for a GPS receiver to use with
USRP. I just finished the first simple one of generating the C/A code
for each satellite. You can check it out on on my blog at
http://www.phys-x.org/grblog/grblog.html (try the link
http://64.6.242.226/grblog/grblog.html since the higher domain
registers need some time to refresh).
Anybody else developing code for GPS so we can pool our efforts?
