OK. so how are you starting gpsd?

Usually something like this:

# gpsd -n /dev/ttyS0

You can see your running gpsd this way:

# pstree -paul | fgrep gpsd

Which seems like gpsd is no running...

It is running. The Trimble unit emits strings on 192.168.142.1:5017. I was using systemd. However, let's take that out of the equation for now:

$ sudo gpsd tcp://192.168.142.1:5017
$ pstree -paul | grep gpsd
  |-gpsd,12951,nobody tcp://192.168.142.1:5017

$ sudo gpsd -D4 -N  tcp://192.168.142.1:5017
