Message Type 118, $GPGSV

Standard NMEA message containing the number of satellites in view, their ID, elevation, azimuth, and SNR value.

Up to four satellites can be contained in a single GSV string so up to three strings are possible to cover up to 12 satellites.

Message format is:

$GPGSV,m,n,vv,i1,e1,a1,s1,i2,e2,a2,s2,i3,e3,a3,s3,i4,e4,a4,s4,*hh<CR><LF>

Where:

m is the total number of GSV messages in this sequence: 1 to 3

n is the sequence number of this message: 1, 2 or 3

vv is the number of satellites in view

i1-4 is the satellite ID

e1-4 is the satellite elevation in degrees

a1-4 is the satellite azimuth in degrees true

s1 is the satellite SNR in dB

hh is the message checksum

Example:

$GPGSV,3,1,09,11,08,210,41,25,13,222,39,20,76,229,46,23,54,281,32*73
$GPGSV,3,2,09,31,39,054,,32,62,149,46,16,24,132,36,04,18,316,*7E
$GPGSV,3,3,09,13,21,271,30,00,00,000,,00,00,000,,00,00,000,*76
