  1. GPS Applications

    BCM / E- Business Technologies Prof. EduardHeindl June 30, 2009 Jaime Navarrete Ortiz
  2. Agenda Background Definition How does GPS work Applications Military Civilian GPS aiding systems The future of GPS Summary BCM/E-Business Technologies
  3. Background Early 70’s: USA’s Department of Defense Military purposes 70’s and 80’s: Experimental blocks of satellites 1993: Initial Operational Capability (IOC) 1994: 24 Satellite constellation in orbit 1995: Full Operational Capability (FOC) Navigation worldwide, map-making, surveying... 2004: GPS on mobile phones BCM/E-Business Technologies
  4. Definition The Global Positioning System (GPS) is a U.S.-owned utility that provides users with positioning, navigation, and timing (PNT) services GPS has become practically the most important tool for transportation systems worldwide BCM/E-Business Technologies
  5. How does GPS work GPS satellites are arranged so that four satellites are placed in each of six orbital planes Signals are sent by the GPS satellites high above the Earth (at the speed of light), each satellite transmits messages containing the time the message was sent with precise information Determine the receiver's location 3D location: latitude, longitude and altitude, and time. BCM/E-Business Technologies
  6. How does GPS work GPS: Very small clock error, results in a large position error Receivers use four or more satellites to solve for x, y, z, and t BCM/E-Business Technologies
  7. How does GPS work The GPS system consists of three types: Space Segment, Control Segment and User Segment BCM/E-Business Technologies
  8. Applications: Military For navigation Find objectives in the dark or in unfamiliar territory Coordinate the movement of troops and supplies. Target tracking Military weapons systems use GPS to track potential ground and air targets; and missile and projectile guidance Mapping and exploration BCM/E-Business Technologies
  9. Applications: Automobiles, roads and highways The GPS offers efficiencies and safety A geographic information system (GIS) stores, analyzes, and displays geographically referenced information provided in large part by GPS. Monitor vehicle location: for scheduling and providing arriving time information. Mass transit systems: improve on-time performance. Automobile GPS Systems: points of interest (POI) and course-planning functionality. Display information about location, speed, direction. Logistics: tracking and forecast of freight. Provide warnings to drivers of potential critical situations, such as traffic violations or crashes. BCM/E-Business Technologies
  10. Applications: Aviation Increase the safety and efficiency of flight Space-based position and navigation: determination for all phases of flight Safely reduce the separation between airplanes: more aircraft to fly, efficient routes, saving time, fuel, and increasing cargo. Safety: increased by the satellite signals augmentation for special aviation applications  greater precision operations are possible. BCM/E-Business Technologies
  11. Applications: Marine Fastest and most accurate method for mariners to navigate Information of the vessels: availability, location, etc. Application named “man overboard” (MOB) GPS data for underwater surveying, buoy placement, and navigational location and mapping Fishing: optimum fishing locations, identify fish migrations Automation of the pick-up, transfer, and placement process of containers BCM/E-Business Technologies
  12. Applications: Emergencies GPS in mobile phones places an emergency location capability in the users: Comprehensive safety net (e.g. 911) Helpful for tracking children In the automobile: “OnStar” by GMC BCM/E-Business Technologies
  13. Applications: Public safety & Disasters Precise location of landmarks, streets, buildings, emergency service resources, and disaster reliefs: protecting life and reduce property loss Efforts for global disasters (hurricanes, tsunamis, earthquakes, etc.) Scientists can study how strain builds up slowly over time in an attempt to characterize and anticipate earthquakes Seismic monitoring networks to locate epicenters of earthquakes and other seismic events. BCM/E-Business Technologies
  14. Applications: Surveying and Mapping Survey markers, buildings, and road construction 3D information for natural and artificial features that can be displayed on maps and models of the world GPS together with GIS are used for timely decision-making and wiser use of resources Yields highly accurate surveying results in real-time at the centimeter-level Unaffected by rain, wind, or reduced sunlight Growing use by professional surveyors and mapping personnel BCM/E-Business Technologies
  15. Applications: Agriculture and Farming Precision farming: soil sample collection, chemical applications control, harvest yield monitors, farm planning, field mapping, tractor guidance and crop scouting Before: difficulty for farmers to correlate production techniques and crop yields with land variability Availability to work during low visibility field conditions Precision agriculture: introduction of high technology tools into the agricultural community that are more accurate, cost effective, and user friendly New tools: the integration of on-board computers, data collection sensors, and GPS time and position reference systems (aided by the GIS) BCM/E-Business Technologies
  16. Applications: Recreation and Fun GPS technology together with electronic mapping has helped to overcome much of the traditional problems associated with unbounded exploration: Hikers, bicyclists, and outdoor adventurers Skydiving: drop-zone Geocaching: hunting game Photography: coordinates for location of photos BCM/E-Business Technologies
  17. Applications: Timing & Business Networks all rely on precision timing for synchronization and operational efficiency: cost savings for companies that depend on precise time, leading to significant advances in capability Banks and businesses: Synchronize their networks  track, update, and manage multiple transactions made by a global network of customers Power companies: enable efficient power transmission and distribution Marketing: GPS systems and survey based research to help them to decide new targets and branches BCM/E-Business Technologies
  18. Helping GPS Augmentation Systems include: Nationwide Differential GPS System (NDGPS) Wide Area Augmentation System (WAAS) Continuously Operation Reference Station (CORS) Global Differential GPS (GDGPS) International GNSS Service (IGS) BCM/E-Business Technologies
  19. The Future of GPS Expected that the majority of GPS users will be in vehicle navigation Automatic machine guidance and control USA: implementation of a second and a third civil signal on GPS satellites, in order to improve accuracy and help the safety-of-life applications (aviation) BCM/E-Business Technologies
  20. Summary GPS has been evolving through time and has helped in the surveying, navigation, agricultural and military fields since it was started to being used. Despite of the fact that at the beginning was designed for military purposes The civil applications have grown faster GPS has replaced the conventional methods Cost effective process, time saving, accuracy and rapidness “New uses of GPS are invented every day and are limited only by the creativity of the human imagination” From: National Space-Based Positioning, Navigation, and Timing Coordination Office.
