One thing I found while reading the documents over the weekend was the minpoll / maxpoll suggested by gpsd for the SHM driver: # gpsd shared memory clock server 127.127.28.0 minpoll 4 maxpoll 4 prefer # PPS requires at least one preferred peer fudge 127.127.28.0 refid GPS fudge 127.127.28.0 time1 +0.130 # coarse processing delay offset is no longer required.
