2.5. GPGSV
GSV, GNSS Satellites in View. One GSV sentence can only provide data for at most 4 satellites, so
several sentences might be required for the full information. Since GSV includes satellites that are not
used as part of the solution, GSV sentence contains more satellites than GGA does.
Example:
$GPGSV,3,1,12,01,05,060,18,02,17,259,43,04,56,287,28,09,08,277,28*77
$GPGSV,3,2,12,10,34,195,46,13,08,125,45,17,67,014,,20,32,048,24*74
$GPGSV,3,3,12,23,13,094,48,24,04,292,24,28,49,178,46,32,06,037,22*7D
