Global positioning system

  1. 1. By: Ian Shea and Austin Brown
  2. 2.  The Global Positioning System (GPS) was developed by the U. S. Department of Defense (DOD), Ivan Getting, and the Massachusetts Institute of Technology (MIT). Originally consisting of 11 orbiting satellites, the GPS--official name NAVSTAR (Navigation System with Timing And Ranging)--was launched by DOD in 1978 strictly for military use.
  3. 3.  AIR FORCE
  4. 4.  The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.
  5. 5.  Nowadays, about 30 active satellites orbit the earth in a distance of 20200 km. GPS satellites transmit signals which enable the exact location of a GPS receiver GPS is being used in aviation, nautical navigation and for the orientation ashore. Further it is used in land surveying and other applications where the determination of the exact position is required. The GPS signal can be used without a fee by any person in possession of a GPS receiver. The correct name of the system is NAVSTAR (Navigation System for Timing and Ranging), but commonly it is referred to as GPS (Global Positioning System).
  6. 6.  TIMELINE
  7. 7.  Remember that horrible bombing in Oklahoma City. Well surveyors used GPS to measure how much the buildings had shifted. The GPS system has settled disputes between land owners. The GPS system has aided marine archaeologists and research vessels in hunting and locating shipwrecks.
  8. 8.  You can get 2D a 3D GPS systems. The GPS system and its data have revealed that Mt. Everest is getting taller! The GPS is in fact the only system today that can show your exact position on Earth anytime, in any weather and it doesn’t matter where you are at the time. At first GPS was strictly for military uses. What about if you think your spouse is cheating? Now there is a key that can be put in your or his vehicle and will track exactly where they are going on any given day. Animal tracking devices are also being placed in pets to keep track of them. One man trusted his GPS so much that he turned right when directed and drove right into a lake!  TRUST IT?
  9. 9.  GPS for Hiking and Hikers Most of the GPS units for hikers are compact, lightweight and some are waterproof as well GPS for Tourists and Tourism Mark the location of your hotel and places to visit, like local museums and other attractions. Think about all the saved time you would have to enjoy yourself, rather than finding your way around. GPS Software If you have been using computers for awhile, you know that there are different applications (software) that virtually do the same thing. GPS is no exception. While some applications will offer somewhat limited maps with major roadways for a particular country, others have very detailed street maps along with marked locations such as hotels, restaurants, gas stations, airports, and the list just goes on and on. Almost anything you can think of, you can find. Voice Guided GPS If you are doing alot of driving, its hard to keep your eyes on a GPS screen, therefore, the developers came up with a solution of creating a "Voice Guided GPS" to make it more safe for the driver. Golf GPS Devices-
