Portable atomic clock could replace GPS

Scientists in the Emergent Photonics Lab (EPic Lab) at the University of Sussex have made a breakthrough to a crucial element of an atomic clock — devices which could reduce our reliance on satellite mapping in the future — using cutting-edge laser beam technology. Their development greatly improves the efficiency of the lancet (which in a traditional clock is responsible for counting), by 80% — something which scientists around the world have been racing to achieve.
