Re: version 1.17 opensource code

Hi,

The change in 1.17 was to make the t_counts represent the data bit
number in the navigation message.  Since the GPS satellites are
synchronized they will all be the same when properly locked on.

In the older versions of the code t_counts represented the number
of bits received and was different for each satellite depending on
how long it had been tracking.  This change allows the program to
more easily record the raw data bits for analysis purposes.

I hope this helps explain it,

Cliff
