Navigation Signal Timing and Ranging Global Positioning System (NAVSTAR
Among these, the Navstar
Global Positioning System (GPS) has become renowned for its highly accurate navigation, position, and timing signals, for which military and civilian users worldwide have found an astounding variety of applications.
Originally called Navstar
Global Positioning System, GPS was first used by the U.S.
It uses 24 satellites called NAVSTAR
, for "navigation system timing and ranging." At a height of more than 12,000 miles, the satellites orbit the Earth every 12 hours in six orbital planes at 55 degrees relative to the plane of the Equator and separated by 60 degrees.
An augmented GPS positioning solution that uses both the US NAVSTAR
IV GPS satellites and the Russian GLONASS satellites determines dozer locations to centimetre accuracy at virtually any location in the mine.
