4.2.6 GPS Satellites in View (GSV)
$GPGSV,<1>,<2>,<3>,<4>,<5>,<6>,<7>,...<4>,<5>,<6>,
<7>*hh<CR><LF>
<1> Total number of GSV sentences to be transmitted
<2> Number of current GSV sentence
<3> Total number of satellites in view, 00 to 12 (leading
zeros will be transmitted)
<4> Satellite PRN number, 01 to 32 (leading zeros will
be transmitted)
<5> Satellite elevation, 00 to 90 degrees (leading zeros
will be transmitted)
<6> Satellite azimuth, 000 to 359 degrees, true (leading
zeros will be transmitted)
<7> Signal to noise ratio (C/No) 00 to 99 dB, null when
not tracking (leading zeros will be transmitted)
NOTE: Items <4>,<5>,<6> and <7> repeat for each satellite
in view to a maximum of four (4) satellites per
sentence. Additional satellites in view information
must be sent in subsequent sentences. These
fields will be null if unused.
