Several sentences are being sent and I currently have no way of disabling the unused ones. I am trying to use $GPGGA because on this GPS it is supposed to be closest to the PPS pulse. I am using ntp-dev-4.2.7p171

What version of ntpd are you using?
Is your GPS sending only $GPGGA, or are there several sentences being
sent each second?
