NAME

GPS::NMEA - Perl interface to GPS equipment using the NMEA Protocol

SYNOPSIS

            

              
              
use GPS::NMEA;
$gps = new GPS::NMEA(  'Port'      => '/dev/ttyS0',
                 'Baud'      => 9600,
              );
            
          

DESCRIPTION

GPS::NMEA allows the connection and use of of a GPS receiver in perl scripts.

Note that latitudes and longitudes are in DMM format.

EXAMPLES

Get the position periodically:

            

              
              
#!/usr/bin/perl
use GPS::NMEA;
my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
                             Baud => 4800);
while(1) {
    my($ns,$lat,$ew,$lon) = $gps->get_position;
    print "($ns,$lat,$ew,$lon)\n";
}
            
          

Get the internal NMEA dump:

            

              
              
   #!/usr/bin/perl
   use GPS::NMEA;
   use Data::Dumper;
     
   my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
                             Baud => 4800);
   while(1) {
       $gps->parse;
     
# Dump internal NMEA data:
       $gps->nmea_data_dump;
     
       # Alternative to look at the internal NMEA data:
       require Data::Dumper;
       print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
   }
   __END__
