The Motorola Oncore UT GPS receiver, which was designed as a precision
time source, has a T-RAIM (time receiver autonomous integrity
monitoring)
feature which, properly configured, switches off the PPS output if
the receiver loses lock.
But lots of low-cost GPS receivers don't do that.
.. including the popular GPS18 LVC. So it's better to have a driver which
reads the serial output of the GPS to confirm lock.
Cheers,
