The coordinates are entered in the saucer Excalibur once you replace the damaged fuel rod. But the coordinates the Queen gave you are too far away. You will need to go to the Pewter Moon, which orbits the planet Poptropica. The coordinates are X-56 Y-52, from the missing journal page under Mordred's bed.
