Note 1. For version 1.5, when not performing positioning, outputs last measured position data.
For version 2.3, IEC, when not performing positioning, outputs last measured position data,
date, and time.
For version 2.3, IEC, when power is turned on, or master reset is performed, the initial time,
date, and position settings are NULL.

SBAS satellites 120 to 138 are represented by 33 to 51
33 to 64 are reserved for SBAS satellite use.
If there are 12 or more GPS satellites when positioning, even if there are SBAS
satellites, the output gives priority to GPS
