GSV message number (1 - 4)
(Version 2.3)
3:
Total number of satellites in view
4:
1st Satellite ID number (01 - 32)
SBAS satellites 120 to 138 are represented by 33 to 51.
(Version 2.3)
33 to 64 are reserved for SBAS satellite use.
(Version 2.3)
5:
1st satellite Elevation, degrees, 90° maximum
6:
1st satellite Azimuth, degrees true, 000 to 359
7:
1st satellite SNR (C/No) 00-99 dB-Hz, null when not tracking
8 - 11: 2nd satellite information
(same as 4 - 7)
(IEC see Note2)
12 - 15:3rd satellite information (same as 4 - 7) (IEC see Note2)
16 - 19:4th satellite information
(same as 4 - 7)
(IEC see Note2)
20: Checksum
Note1
Each GSV sentence includes 4 satellites, so the number of GSV sentences
varys based on
the number of satellites detected.
Note2 A variable number of “satellite ID-elevation-azimuth-SNR” sets are allowed up to a maximum
of four sets per message. Null fields are not output when less than four sets are transmitted.

4, 5: Longitude (deg, min), E / W
6: Mode
indicator
N = No fix. Satellite system not used in position fix, or fix not valid.
A = Autonomous. Satellite system used in non-differential mode in position fix.
D = Differential. Satellite system used in differential mode in position fix.
S = Simulator mode.
7:
Total number of satellites in use
8:
HDOP (0 - 20)
9:
Antenna altitude, m, mean-sea-level (geoid)
10: Geoidal separation, m
11:
Age of differential data (NULL if not performing DGPS positioning)
12: Differential reference station ID (NULL if not performing DGPS positioning)
13: Checksum
Note When not performing position fixing, outputs last measured position data, and time.
When power is turned on, or master reset is performed, the initial time, and position settings
are NULL.
