Control and Monitering Stations on earth
GPS receivers owned by Users
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
How GPS Receivers Work?
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”
2-D & 3-DTrilateration
Techniques to Improve Accuracy:
Wide Area Augmentation System
A Local Area Augmentation System
A Carrier-Phase Enhancement
Wide Area GPS Enhancement
Working of GPS in Vehicles
It helps in accident prevention .
Identification of repairs in vehile and thus the informs the driver about problem .
Intimates of the traffic in the near by and also advices which path to choose
Planning a Navigation Route Start = Waypoint
Model of vehicle tracking system
Vehicle Tracking System in a car
Aviators throughout the world use the Global Positioning System (GPS) to increase the safety and efficiency of flight.
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.
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.
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.
