Deep within a concrete-loaded pit just outside Munich, Germany, researchers are using some of the very best measurements ever of Earth’s movement. They are utilizing big, purple lasers set 15 metres under Earth’s area to get knowledge that could assistance make GPS navigation much more precise.
GPS makes use of measurements from satellites which have to be calibrated with measurements of Earth’s orientation in place, which is constantly changing. “If we do not measure it, our GPS site that we have in our vehicle and our cell phone would be …
