: Total number of GSV messages (1 - 3) (Version 2.1) 

2 

: GSV message number (1 - 3) (Version 2.1)

: Total number of GSV messages (1 - 4) (Version 2.3, IEC) 

2 

: GSV message number (1 - 4) (Version 2.3, IEC) 

3 

: Satellites in view 

4 

: 1st satellite PRN number (01 - 32) (2 digit fixed length) 
  SBAS satellites 120 to 138 are represented by 33 to 51. (Version 2.3, IEC) 
  33 to 64 are reserved for SBAS satellite use. (Version 2.3, IEC) 

5 

: 1st satellite elevation angle (00 - 32) (2 digit fixed length) 

6 

: 1st satellite bearing angle (00 - 90 deg) (3 digit fixed length) 

7 

: 1st satellite SNR signal strength C/No (00 - 99dB) (2 digit fixed length) 

8 – 11 

: 2nd satellite information (same as 4 - 7) 

12 – 15 

: 3rd satellite information (same as 4 - 7) 

16 – 19 

: 4th satellite information (same as 4 - 7) 

         Null fields are not required for unused sets when less than four sets are transmitted. (IEC) 
20 : 

Checksum 

   

Note.  Each GSV sentence includes 4 satellites, so the number of GSV sentences varies based on 

the number of satellites detected. 

              If bit rate is set to 4800bps, Maximum GSV message numbers are three (Max 12 satellites).     
              Therefore, if satellites in view are 12 GPS satellites and 1 SBAS satellite (total 13 satellites),   
              the GSV sentence is output only 11 GPS satellites and 1 SBAS satellite (total 12 satellites).
