The existing three-satellite COMPASS/BeiDou navigation system has played an important role in offering efficient positioning, timing, communication services and differential GPS information in surveying, telecommunications, transportation, meteorology, forest fire prevention, disaster forecast and public security areas. On the basis of the COMPASS/BeiDou Navigation Test System, China has started to build a system with global coverage.
