$PASHQ,GSV,[c1]
This command queries the GSV message, where c1 is the optional port designator
for the output of the response. If a port is not specified, the receiver sends the
response to the current port.
$GPGSV
The GSV message contains the PRN number, elevation, azimuth, and signal to
noise ration for each visible satellite. This message contains data for a maximum
of four satellites. If seven satellites are visible, two GSV messages are output.
The total number of messages transmitted and the number of messages
transmitted are indicated in the first two fields of the first message.The first three
messages contain GPS satellite information and the second three messages
contain GLONASS satellite information.
The message is output in the format:
$GPGSV,d1,d2,d3,d4,d5,d6,f7,d8,d9,d10,f11,d12,d13,d14,f15,d16,
d17,d18,f19*hh
