1.UTC of position fix

2.Status: A=data valid, V=navigation receiver warning

3.Latitude, N/S

4.Longitude, E/W

5.Speed over ground, knots

6.Course over ground, degrees true

7.Date: dd/mm/yy

8.magnetic variation, degrees E/W

9.Mode indicator(see note)

10.Checksum

NOTE Positioning system Mode indicator:

A = Autonomous

D = Differential

E = Estimated (dead reckoning)

M = Manual input

S = Simulator

N = Data not valid

The Mode indicator field supplements the Status field. The Status field shall be set to V=invalid for all values of Operating Mode except for A=Autonomous and D=Differential. The positioning system Mode indicator and Status field shall not be null fields.
