It presentation[1][1]final
- 1. IT Presentation IT innovation------ GPS Jasmine Che Shirley Wan Sunyan
- 2. Project Work Flow & Job Division Learn the IT skills Decide a topic Combine all the e.g. using different parts done before that we are software to collect together, as well as interested data and with more analysis information Jasmine: Finding information about History of GPS Shirley: Finding “ Applications ”and “Advantages and Disadvantages ” Sunyan: Handling survey and data
- 3. Objective • How GPS work • Discover how GPS technology changes human lives • What are the daily life application of GPS • What are the benefits and shortcoming
- 4. History • The Global Positioning System (GPS) was developed by : the U. S. Department of Defense (DOD), Ivan Getting 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
- 5. 1957 Additional inspiration for the GPS system came when the Soviet Union launched the first Sputnik 1960 The first satellite navigation system, Transit, was used by the United States Navy and was first successfully tested 1967 the U.S. Navy developed the Timation satellite which proved the ability to place accurate clocks in space, a technology the GPS system relies upon. 1970s, the ground-based Omega Navigation System, based on signal phase comparison, became the first world-wide radio navigation system. 1978 The first experimental Block-I GPS satellite was launched in February 1978. The GPS satellites were initially manufactured by Rockwell International and are now manufactured by Lockheed Martin.
- 7. Survey Importance of mobile phone 120 100 80 Marks 60 40 20 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 When 100 is full marks, most respondents ranked the importance of mobile phone as 80 marks or above.
- 8. How GPS function? • They work on a very simple principal called trilateration. • GPS is really a group of 27 Earth-orbiting satellites in geostationary orbit 12,000 miles above earth http://www.youtube.com/watch?v=DCdsGRLo H5E
- 9. Applications Social Military Aircraft Tectonic Telecommunication Navigation Navigation path analysis
- 10. Social Application • Telecommunication: GPS is widely used in our mobile phone and computer, for example, the phone can show the routes which can arrive to the destination with Automotive navigation system • Navigation: GPS has been adopted on some cargo in order to measure the velocity and locate the orientation.
- 11. • Aircraft path: Some data, e.g. the speed, direction and the altitude will be recorded and reported. • Tectonic analysis: With GPS technology, we can measure the faulting activities directly. Military application • Navigation: The soldier can find the object they need and gather at a specific location even though they are in the dark. http://www.youtube.com/watch?v=DCdsGRLoH5E
- 12. Advantages • Very handy: widely applicable • Good use on water navigation: would not obstruct the reception of signal • Useful application on science: detect the destructed building and roads damaged • Benefit in Business: entrepreneur can keep their eyes on the business closely • Making map: we can modify the map easily
- 13. Disadvantages • Possible Failures: Tall building will block the satellite signal. It may prevent you from receiving the position correctly. • The cost is expensive: The cost of some high technology GPS with accurate locating function and updating information would be very expensive. • Short battery life: Since this system depends on the electricity from battery, the electricity will drain after a period of time.
