[Thumbgps-devel] Article -- Macx-1: GPS receiver with standard USB connector and PPS support

[tz]

They need to disable the dead reckoning feature or at least insure pps
doesn't go out if there is a problem with the fix.  For maps/nav, keeping
the stream intact for a few seconds is good, but not if you need precision.

This does not affect the hotstart memory, only what it does if it loses
enough signal so the fix is lost.
