Telematics GPS Definition
The Global Positioning System, usually called GPS (the
US military refers to it as NAVSTAR), is a satellite
navigation system used for determining one's precise location and
providing a highly accurate time reference almost anywhere on Earth
or in Earth orbit. It uses an intermediate circular orbit (ICO) satellite
constellation of at least 24 satellites.
The GPS system was designed by and is controlled by the United States
Department of Defense and can be used by anyone, free of charge.
The GPS system is divided into three segments: space, control, and
user. The space segment comprises the GPS satellite constellation.
The control segment comprises ground stations around the world that
are responsible for monitoring the flight paths of the GPS satellites,
synchronizing the satellites' onboard atomic clocks, and uploading
almanac data for transmission by the satellites. The user segment
comsists of GPS receivers used for both military and civilian applications.
A GPS receiver (GPSR) decodes time signal transmissions
from multiple satellites and calculates its position by trilateration.
The cost of maintaining the system is approximately US$400 million
per year, including the replacement of aging satellites. The first
of 24 satellites that form the current GPS constellation (Block
II) was placed into orbit on February 14, 1989. The 50th GPS
satellite since the beginning in 1978 was launched March 21, 2004
aboard a Delta II rocket (see article in External links section,
below).
