This is a GPS module test sketch for Arduino based on a LCD1602 shield. You can either save it to local INO file and build width Arduino IDE (TinyGPS library is required). You can also compile it online into a HEX file and upload to Arduino with AVRDUDE or other uploading utilities.

#include <LCD4Bit_mod.h>
#include <TinyGPS.h>

LCD4Bit_mod lcd = LCD4Bit_mod(2);
TinyGPS gps;

void setup()
{
    // change the baudrate to adapt with GPS module
    Serial.begin(9600);
    lcd.init();
}

void loop()
{
    static bool ready = false;
    if (!Serial.available()) return;
    char c = Serial.read();
    // push NMEA characters to TinyGPS
    if (!gps.encode(c)) {
        // parsed data not ready
        if (!ready) lcd.print(c);
        return;
    }

      char buf[16];
      unsigned long fix_age;
      long lat, lon;
      gps.get_position(&lat, &lon, &fix_age);
      sprintf(buf, "LAT:%d.%05ld",
        (int)(lat / 100000), lat % 100000);
      lcd.cursorTo(1, 0);
      lcd.printIn(buf);
      sprintf(buf, "LON:%d.%05ld",
        (int)(lon / 100000), lon % 100000);
      lcd.cursorTo(2, 0);
      lcd.printIn(buf);
      ready = true;
}
