Clearly your mailer is stripping out line ends from the messages sent out. The email I sent you had a line break at the end of every line. Your quote of it has stripped them all out. Strange.
Anyway, so gpsd is working. It is the communication with chrony that does not seem t obe working. What is your /etc/chrony.conf file? Are you using a socket or an shm to communicate from gpsd to chrony? William G.

My GPS HAT has a fix. I am getting NMEA messages. gpsmon /dev/serial0 shows valid NMEA messages.

You gps is not getting any data, and thus pps cannot work. Your system needs to get the approximate time ( to better than 1/4 of a second) from somewhere else than PPS, since PPS give no information about the actual time. Just when the turn of the second occurs. What is your chrony.conf file? How have you connected up gpsd? Is it seeing the gps source? William G.
