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.

Is so, what kind of gain did you place before the board? > > Thanks, > > Chris > > > _______________________________________________ > Discuss-gnuradio mailing list > [email protected] > http://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
