The gpsd will output assorted parameters, including current
position, ...
You can take this - or even output from a nearby (1m) GPS, and the
bitstream input and output to the GPS chip, and try to work out what
the chip sends out.
I don't understand what is meant by a nearby (1m) GPS. How does the
device communicate with a nearby GPS?
It doesn't - at all.
However, in the absence of a GPS daemon that understands the chip
output, if the chip could just be turned on, the nearby GPS could be
used to determine (almost exactly) what signals are going into the chip,
which makes decoding the protocol easier.
