As far as I know (I'm not an expert on the lower level stuff) this
happens because a firmware is loaded to the chip when it boots. This
firmware only needs to be reloaded to the chip after it is turned off
completely. Just rebooting the device won't cut the power from the GPS
chip and thus doesn't wipe the firmware from it. Now, if an OTA is
providing a new firmware that is incompatible with the old one, it may
happen that Ubuntu expects the newer version but the chip still has the
older version until you go through the complete power-off cycle and with
that make it upload the newer firmware.

This means, you don't need to do this every time you want to use GPS,
but you may need to do this if you experience GPS problems again after
another system update.

Br,
Michael
