mgray,
Thanks for the response. Your script looks fine to me, but I'll try
running it. Perhaps you typed one second at the command prompt.
I tried to read the data as 64 bit floats, but it looked strange
(typical values 1e13) and I quickly gave up on that.
It appears that the first 7000 samples are bad. I attached a plot of
the mag of the first 10000. The remainder look like the last chunk on
the plot. I still cannot acquire a signal, but I'm working on that
(could be my fault).
BTW, I am working with gps_4m_complex.21Apr2005.dat
Thanks,
Chris
