GM862-GPS Software User Guide1vv0300729 Rev. 4 - 24/01/075.4.4 GSV - GNSS Satellites in ViewThis sentence reports the number of satellites (SV) in view, satellite ID numbers, elevation, azimuthand SNR value.There could be four satellites information per transmission so, if the number of satellites in view isbigger, separated GSV sentences will be generated. The number of sentence in transmission and thetotal to be transmitted is shown in the first 2 fields of the sentence.Table G contains the values for the following example:$GPGSV,2,1,07,07,79,048,42,02,51,062,43,26,36,256,42,27,27,138,42*71$GPGSV,2,2,07,09,23,313,42,04,19,159,41,15,12,041,42*41Table G: GSV Data FormatName Example Units DescriptionMessage ID $GPGSV GSV protocol headerNumber of 2 Range 1 to 3MessagesMessage 1 Range 1 to 3Number1Satellites in 07ViewSatellite ID 07 Channel 1 (Range 1 to 32)Elevation 79 degreesAzimuth 048 degreesSNR (C/No) 42 dBHz.... .... ....Satellite ID 27 Channel 4 (Range 1 to 32)Elevation 27 degrees Channel 4 (Maximum 90)Azimuth 138 degrees Channel 4 (True, Range 0 to 359)SNR (C/No) 42 dBHz Range 0 to 99, null when not trackingChecksum *71 End of message terminationReproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 100 of 111
