INDEX • What is GPS? • Background & History. • Components of System. • Basic Principle of GPS. • Area of Application? • Advancement in GPS. • Conclusion
What is GPS? • It’s a Satellite Navigation System. • It gives accurate position of receiver up to 100m • Transmit position and time data. • GPS uses "man-made stars" as reference points to calculate positions accurate to a matter of meters. • 24+ satellites and 5 monitoring stations. • 12 hours orbital time • Free of Cost
Monitoring Stations US Space Command Cape Canaveral Hawaii Kwajalein Atoll Diego Garcia Ascension Is.
Various Devices Used for GPS A GPS Receiver GPS Phones GPS in CAR
Background & History • 1969—Defense Navigation Satellite System (DNSS) formed • 1973—NAVSTAR Global Positioning System developed • 1978—first 4 satellites launched Delta rocket launch • 1993—24th satellite launched; initial operational capability • 1995—full operational capability • May 2000—Military accuracy available to all users
Basic Principle of GPS. • Position of any receiver is calculated using principle of triangulation (trilateration).
Area of Application? • Military. • Search and rescue. • Disaster relief. • Surveying. • Marine, aeronautical and terrestrial navigation. • Remote controlled vehicle and robot guidance. • Satellite positioning and tracking. • Shipping.
Advancement in GPS • Beidon – China's regional system that China has proposed to expand into a global system named COMPASS. • Galileo – a proposed global system being developed by the European Union, joined by China, Israel, India, Morocco, Saudi Arabia, South Korea, and Ukraine, planned to be operational by 2013. • GLONASS – Russia's global system which is being restored to full availability in partnership with India. • Indian Regional Navigational Satellite System (IRNSS) – India's proposed regional system. • QZSS – Japanese proposed regional system, adding better coverage to the Japanese Islands
Conclusion • GPS is a vibrant technology with its applications extended to areas such as Military, Search and rescue, surveillance, Navigation etc. • As the technology grows further we might see its usage extended to common-man, just like mobile phones.
