Chris,
I have successfully done coarse acquisition using the correlator developed
here,
https://projects.cecs.pdx.edu/~icarroll/SoftwareGPSCorrelator/index.cgi/wiki
A plot of the 'acquisition' is here
http://64.6.242.226/grblog/uploaded_images/sat_18-714418.png
for satellite PRN 18 with a code offset of 1988 as shown by the 'spike'. The
gain for the dbsrx was 86 dB while using an active external antenna to get 28
dB more of gain. More details on my blog,
http://64.6.242.226/grblog/grblog.html
Not sure if I will have a link to the sample data because it is almost 2 GB
compressed, yikes! If you know how to break up the data let me know and I will
upload just the begininning of the file, since it is just over a minute of
data.
