GPS problem

Hello, I tried this code over arduino168 and the L LED(orange) is lighting up even when then gps is not connected to the arduino. What is it meens?

CODE: http://www.arduino.cc/playground/Tutorials/GPS

void loop() {
   digitalWrite(ledPin, HIGH);

It looks like nothing is being read from the GPS.

[edit]That’s quite a badly-written example.[/edit]
