From a *very* quick read of the doc’s:
1) The device *does* have a position hold capability

Sparkfun is now selling the Ublox F9P L1/L2 GPS receiver module on a board
($219). The F9P supports GPS/Galileo/Glonass/Beidou and tracks L1/L2 data. It
outputs carrier phase data and has survey-in and fixed position support along
with RTK support (10 mm accuracy). Looks like the F9P has 1
The official RPi touchscreen mounted in a Smartipi case (with the extended back
cover) works very well. That's how I have my alarm clock configured. The GPS

Lady Heather supports the Ublox receivers and can set the time pulse
outputs, etc. See the "P" keyboard menu. If Heather
