What do you mean by "Eliminating"?

other than set it as a truechimer in the configuration?

Get a source of NMEA data that's presented at a consistent offset from the
PPS pulse.

Unless someone needs to share position and velocity data
I don't understand why gpsd is used to proxy NMEA data.  The NMEA (or ATOM)
driver is sufficient.
