Appendix-20
15：Mode indicator (see Notes 1 and 2)
NOTE 1 Positioning system mode indicator:
A = Autonomous mode;
D = Differential mode;
S = Simulator mode;
N = Data not valid.
NOTE 2 The positioning system mode indicator field supplements the positioning system status fields (fields
1 and 2), the status fields should be set to V = invalid for all values of mode indicator except for A = Autonomous
and D = Differential. The positioning system mode indicator should not be null fields.
