    • GPS PRESENTED BY: MD ABU SHAHAM 10-MBA-18 AMUMC
    • INTRODUCTION OF GPS GPS is a navigation and precise- positioning tool. Orbiting navigational satellites. Transmit position and time data. Developed by DoD in 1973. GPS uses for location,navigation,tracking,Mapping and timing.
    • The GPS Constellation
    • HOW GPS WORKS?
    • GPS SEGMENTSGPS systems are made up of 3 segments  Space Segment (SS)  Control Segment (CS)  User Segment (US)
    • 1 - Space Segment- contains 30 GPS satellites- orbiting at an altitude of approximately 20,200 kilometers- each satellite makes two complete orbits in 12 hours( twice a day)- orbits are designed so that at the very least, six satellites are always within line of sight from any location on the planet
    • Continues…
    • 2 - Control Segment The CS consists of 3 entities: Master Control Station - located Falcon Air Force Base in Colorado , is responsible for overall management of the remote monitoring and transmission . Monitor Stations - Six monitor stations are located world wide. - They checks the exact altitude, position, speed, and overall health of the orbiting satellites. Ground Antennas -they transmit correction information to individual satellites.
    • 3 - User Segment-The users GPS receiver is the user segment of the GPS system-They can also include a display for showing location and speed information to the user.
    • GPS Communication and Control
    • What is happening?GPS satellite circle the earth twice a day in a very precise orbit and transmit signal information to earth.GPS receivers take this information and use triangulation to calculate the user’s exact location. Essentially , the GPS receivers compares the time a signal was transmitted by satellite with the time it was received. The time difference tell the GPS receiver how far away the satellite is. Now with distance measurement from a few more satellites, the receiver can determine the user’s position and display it on the unit’s electronic map.
    • APPLICATIONS OF GPS
    • TRANSPORTATION IT USES AIR,WATER ,SURFACE TRANSPORTATION. TO FIND ROUTES. IT ENABLES FIND EASY ROUTES. TO FIND EXACT LOCATION
    • VEHICLESTO TRACKINGFIND ROUTEFIND LOCATION
    • MILITARY INTHE TIME OF WAR TO ATTACK ENEMIES TO FIND BOARDERS
    • AGRICULTURE SPRAYING PESTICIDE
    • TOURISM TOFIND LOCATION FOR TREKKING FOR MOUNTAIN BIKERS
    • WILDLIFE TO FIND WILDLIFE AND FOREST AREA TO COUNTING WILD ANIMALS
    • OTHER USES SURVEYING MAPPING IDENTIFY NATIONAL BOARDERS
    • CONCLUSIONThe technology of the Global PositioningSystem is allowing for huge changes in society.The applications using GPS are constantlygrowing. The cost of the receivers is droppingwhile at the same time the accuracy of thesystem is improving. This affects everyone withthings such as faster Internet speed and saferplane landings.Even though the system wasoriginally developed for military purposes and itis used to support a broad range of defense.
