   This sample demonstrates TinyGPS++'s capacity for extracting custom
   fields from any NMEA sentence.  TinyGPS++ has built-in facilities for
   extracting latitude, longitude, altitude, etc., from the $GPGLL and
   $GPRMC sentences.  But with the TinyGPSCustom type, you can extract
   other NMEA fields, even from non-standard NMEA sentences.

   It requires the use of SoftwareSerial, and assumes that you have a
   9600-baud serial GPS device hooked up on pins 4(RX) and 3(TX).

static const uint32_t GPSBaud = 9600;

// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);

/*
   By declaring TinyGPSCustom objects like this, we announce that we
   are interested in the 15th, 16th, and 17th fields in the $GPGSA
   sentence, respectively the PDOP (F("positional dilution of precision")),
   HDOP (F("horizontal...")), and VDOP (F("vertical...")).

   (Counting starts with the field immediately following the sentence name,
   i.e. $GPGSA.  For more information on NMEA sentences, consult your
   GPS module's documentation and/or http://aprs.gids.nl/nmea/.)

   If your GPS module doesn't support the $GPGSA sentence, then you
   won't get any output from this program.
