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__
