Transcript

  • 1. Satellite orbiting the earth Control and Monitering Stations on earth GPS receivers owned by Users
  • 2. The GPS satellite system • It consist of full constellation of 24 satellites • These satillites are travelling at a speed of 7000 miles per hour • Transmitter power is only 50 watts or less. • They complete two complete orbits in less than 24 hours
  • 3. How GPS Receivers Work?
  • 4. Position is Based on Time T + 3 Distance between satellite and receiver = “3 times the speed of light” T Signal leaves satellite at time “T” Signal is picked up by the receiver at time “T + 3”
  • 5. • 2-D & 3-DTrilateration
  • 6. Techniques to Improve Accuracy: • Differential GPS • Wide Area Augmentation System • A Local Area Augmentation System • A Carrier-Phase Enhancement • Wide Area GPS Enhancement
  • 7. Im Here
  • 8. Working of GPS in Vehicles
  • 9. • It helps in accident prevention . • Identification of repairs in vehile and thus the informs the driver about problem . • Better navigation • Intimates of the traffic in the near by and also advices which path to choose
  • 10. Planning a Navigation Route Start = Waypoint
  • 11. Model of vehicle tracking system
  • 12. Aviation • Aviators throughout the world use the Global Positioning System (GPS) to increase the safety and efficiency of flight.
  • 13. • Improved approaches to airports • improved Systems for special aviation applications, such as landing planes during poor visibility conditions. In those cases, even greater precision operations are possible.
  • 14. 29 GPS enables researchers to explore the Earth environment including the atmosphere, ionosphere and gravity field. GPS survey equipment has helped in decting natural disasters Navigation made easy GPS is a free service and u just need to purchace a device GPS functionality has now started to move into mobile phones.
  • 15. • Gps services will be our future Key navigation systems. • As Gps systems are cost effictive , even a common man can afford them. • Already gps is use in Major cities in our Country.
