Satcom 5
The Global Positioning System (GPS) uses 24 satellites and their ground stations to form a worldwide radio-navigation system. The satellites orbit the Earth every 12 hours at speeds of 7,000 miles per hour at an altitude of 10,900 nautical miles. GPS works by using triangulation - satellites transmit radio signals that allow receivers to calculate their distance and determine their location by measuring the time it takes for signals to travel from at least three satellites. While very precise, the atomic clocks on satellites and signal distortions can introduce small errors into the system. GPS has many applications including land surveying, navigation of vehicles, boats and aircraft, and recreational activities.

Gps
GPS uses trilateration to determine a receiver's location based on distance measurements to multiple satellites. The receiver uses signal transit times to calculate distances to at least four satellites. Each distance defines a sphere around the satellite, and the intersection of these spheres pinpoints the receiver's location. GPS consists of three segments - space, control, and user. The space segment consists of 32+ satellites. The control segment monitors and controls the satellites. Users can access GPS for civilian and military navigation, tracking, and timing applications.

- 2. Contents What is GPS The need for positioning system Segments of GPS • Space Segment • Control segment •Users Segment How GPS Works TRIANGULATION Applications of GPS
- 3. What is GPS ?? GPS, which stands for Global Positioning System, is the only system today able to show you your exact position on the Earth anytime, in any weather, anywhere. Full name : NAVSTAR GPS - NAVigation Satellite Time And Ranging Global Positioning System
- 4. The need for positioning system From the beginning of civilization, people wanted to know where they are or how to go to somewhere. Ancient sailors used wind and stars to get the direction. Also people have been using compass, map, and other methods to know their location and direction.
- 5. GPS can tell you where you are Developed and maintained by the US Department of Defense (DOD) Satellite Based 24 satellites 20,200 km high orbit Six orbital planes with four satellites each 55 inclination with equator
- 6. Segments of GPS 1. Space Segment A constellation of 24 satellites 2. Control segment A network of earth-based facilities 3. Users Segment
- 7. SPACE SEGMENT 24 satellite vehicles 6 obital planes Obital period of 11 hr 55 min 20,200 km elevation above Earth Five to eight satellites visible from any point on Earth
- 8. CONTROL SEGMENT Monitor and control GPS satellites One master control station (MCS) Five monitor stations Three ground antennas
- 10. User Segment • Receive signal from satellites • calculate current position and speed/direction
- 11. How GPS Works ……… Uses measurements from 4+ satellites Distance = travel time x speed of light
- 12. Time Difference •The GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. • The time difference tells the GPS receiver how far away the satellite is.
- 13. Calculating Distance Velocity x Time = Distance Radio waves travel at the speed of light, roughly 186,000 miles per second (mps) If it took 0.06 seconds to receive a signal transmitted by a satellite floating directly overhead, use this formula to find your distance from the satellite. 186,000 mps x 0.06 seconds = 11,160 miles
- 14. TRIANGULATION • Suppose + A Satellite + Satellite B Satellite A to our position is 11,000 miles • At this point we could be located anywhere on the specified sphere • Next, let us take another measurement from a second satellite, Satellite B •Now our position is narrowed down to the intersection of theses two sphere
- 15. Determining GPS Position + Satellite A + Satellite B + C Satellite •Taking another measurement from a 3rd satellite narrows our position down even further, to the two points • These points are located where the 3rd sphere cuts through the intersection of first two spheres •So by ranging from 3 satellites we can narrow our position to just two points in space •We could make a 4th measurement from another satellite to determine the true point • Or, We can eliminate one of the two points that gives a point which may be too far from the earth • However, GPS receivers use a 4th satellite to precisely locate our position
- 17. Applications of GPS Military Applications • Digital Assistant for soldiers (personal navigation) • Search and rescue missions • Detect nuclear detonation with sensors on satellites (optical sensor, X-ray sensor, EMP sensor, etc..)
- 18. Civilian Applications • Vehicle navigation (for cars, airplanes, and ships) - Use GPS to determine position, speed, and direction
- 19. Civilian Applications • Used in map-making and land surveying • Various usages in many fields of industry • Outdoor Activities (Hike/bike trails, GeoCaching)
- 20. Civilian Applications • Location-based service (LBS), Social Network Service (SNS) - Finding the location of family or friend - Integrate current location with social network - Using GPS-enabled phones (mostly smart phones)
