NoteThe datagram format described here remains the property of the organization that defined it. This datagram description is not complete. If you need more information, contact the owner.
|
1 |
$PTNL: Talker identifier |
|
2 |
GGK: Datagram identifier |
|
3 |
hhmmss.ss: Coordinated Universal Time (UTC) of the current position |
|
4 |
ddmmyy: Day, month and year |
|
5 |
dddmm.mmmmmmmm: Latitude (degrees) |
|
6 |
a: Direction of latitude
|
|
7 |
dddmm.mmmmmmmm: Longitude (degrees) |
|
8 |
a: Direction of longitude
|
|
9 |
x: GPS quality indicator () |
|
10 |
zz: Number of satellites in use (00 - 12) (The number of satellites may be different from the number in view.) |
|
11 |
w.w: PDOP (Position dilution of precision) |
|
12 |
EHTaaa.bbb: Ellipsoidal height of fix |
|
13 |
M: Ellipsoid height (metres) |
NoteThe PTNL, GGK datagram is longer than the NMEA-0183 standard of 80 characters. The latitude and longitude are in the datum and ellipsoid of the selected reference frame.
GPS quality indicator
Quality indicator 0 (zero) means that fix is not available or invalid. Other values:
|
2 |
Differential, floating carrier phase integer-based solution, RTK (float) |
|
3 |
Differential, fixed carrier phase integer-based solution, RTK (fixed) |
|
4 |
Differential, code phase only solution (DGPS) |
|
5 |
WAAS corrected differential position |
|
6 |
RTK network position (float solution) |
|
7 |
RTK network position (fixed solution) |
