GPS Navigation Systems: What Next?

Technology has achieved many useful developments in satellite
navigation systems that allow a small electronic device to
navigate its exact location (Longitude, Latitude and Altitude)
through satellite. When it knows its position, the navigation
device calculates the navigation information including terrain,
directions, roads and more.
Nowadays, most vehicles come with the satellite navigation
devices pre-installed in them. These devices are generally used
by motor vehicle drivers, military, outdoorsmen, boaters and for
other military applications.
The well known satellite system that is fully functional at the
time of this writing is the GPS or the Global Navigation System.
GPS in the United States contains 24 to 27 satellites orbiting
at an altitude of approximately 20,000 km with an inclination
of 55 degrees in six different planes.
The Russian counterpart to GPS is called the GLONASS, which is
derived from GLObal Navigation Satellite System. Though the
initial satellites for GLONASS were launched in 1982, the
system was not fully operational till 1995. The GLONASS has
deteriorated to only 12 satellites, due to economic
difficulties. The Russian GLONASS constellation is expected to
become fully functional by 2010 and there are plans to include
India as well.
The European Union is working on EGNOS derived from European
Geostationary Navigation Overlay System. It consists of 3
satellites intending to supplement the GPS and GLONASS systems
by determining the accurate signals and position with in 5
meters. It is expected to function in 2006.
The European Space Agency is working on introducing an
alternative to GPS, called Galileo. The receivers will be able
to combine the signals of 30 Galileo satellites and 28 GPS
satellites to get highly accurate positions.
There are many satellite navigation systems yet to launch in
several countries. The Satellite system of France is called the
DORIS (Doppler Orbitography and Radio-positioning Integrated by
Satellite) The Chinese system is called BEIDOU, but these
satellite systems do not come under the caliber of GPS, GLONASS
and Galileo.
