Field#

Field Name

Description

F1

time

UTC time for position fix in hours, minutes, seconds (hhmmss.ss)
(000000.00 to 235959.99)

F2

Lat

Latitude in degrees and decimal minutes (ddmm.mmmmmm)
(0000.000000 to 8959.999999)

F3

N/S

Direction of latitude (N=north, S=south)

F4

Lon

Longitude in degrees and decimal minutes (dddmm.mmmmmm)
(00000.000000 to 17959.999999)

F5

E/W

Direction of longitude (E=east, W=west)

F6

quality

Quality of the position fix (0 to 8)

0 = invalid solution
1 = Standalone GPS fix
2 = DGPS fix
3 = PPS fix

5 = Float RTK
6 = estimated (dead reckoning)
7 = Manual input mode
8 = Simulation mode

F7

used

Number of used satellites in the position fix

F8

hdop

Horizontal dilution of precision

F9

Alt

Altitude above mean-sea-level (geoidal height) in meters

F10

M

Units for altitude (M=meters)

F11

separation

Geoidal separation (difference between the WGS-84 earth
ellipsoid and mean-sea-level, where “-” means mean-sea-level is
below ellipsoid) in meters.

F12

M

Units for geoidal separation (M=meters)

F13

age

Time since last dGPS data was received in seconds
