GPS Navigation Methods: What Next?
Go to: Previous Article Next Article
Technology has achieved numerous useful developments in satellite tv for pc navigation methods that enable a small electronic device to navigate its exact location (Longitude, Latitude and Altitude) by way of satellite tv for pc. When it knows its position, the navigation device calculates the navigation information including terrain, directions, roads and extra.
Nowadays, most vehicles come with the satellite navigation devices pre-installed in them. These devices are typically utilized by motor vehicle drivers, military, outdoorsmen, boaters and for other military applications.
The nicely recognized satellite tv for pc process that is completely practical at the time of this writing is the GPS or the Global Navigation Method. GPS within 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 unique planes.
The Russian counterpart to GPS is named the GLONASS, which is derived from International Navigation Satellite tv for pc Method. Though the initial satellites for GLONASS were launched in 1982, the system was not completely operational till 1995. The GLONASS has deteriorated to only 12 satellites, as a result of economic difficulties. The Russian GLONASS constellation is expected to become entirely practical by 2010 and you can find plans to consist of India as well.
The European Union is operating on EGNOS derived from European Geostationary Navigation Overlay Technique. It consists of 3 satellites intending to supplement the GPS and GLONASS techniques by determining the correct signals and position with in 5 meters. It's expected to function in 2006.
The European Space Agency is operating on introducing an alternative to GPS, termed 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 lots of satellite navigation devices yet to launch in numerous countries. The Satellite tv for pc technique of France is termed the DORIS (Doppler Orbitography and Radio-positioning Integrated by Satellite) The Chinese system is called BEIDOU, but these satellite systems don't come under the caliber of GPS, GLONASS and Galileo.
