Checksum (Version 1.5, 2.1)
12: Mode indicator (Version 2.3,IEC)
A = Autonomous mode
D = Differential mode
N = Data not valid
S = Simulator mode
P = SBAS mode (IEC only)
13: Checksum (Version 2.3)
13: Navigational status
S = Safe
C = Caution
U = Unsafe
V = Not Valid
14: Checksum
Note
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.
