What does GPS stand for? Is it Global Positioning System or Geo Positioning System?
Global Positioning System (GPS) is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. The Global Positioning System is mainly funded and controlled by the U.S Department of Defense (DOD). The system was initially designed for the operation of U. S. military. But today, there are also many civil users of GPS across the whole world. The civil users are allowed to use the Standard Positioning Service without any kind of charge or restrictions.Global Positioning System tracking is a method of working out exactly where something is. A GPS tracking system, for example, may be placed in a vehicle, on a cell phone, or on special GPS devices, which can either be a fixed or portable unit. GPS works by providing information on exact location. It can also track the movement of a vehicle or person. So, for example, a GPS tracking system can be used by a company to monitor the route and progress of a delivery truck, and by parents to check on the location of their child, or even to monitor high-valued assets in transit.A GPS tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction. So, a GPS tracking system can potentially give both real-time and historic navigation data on any kind of journey.GPS provides special satellite signals, which are processed by a receiver. These GPS receivers not only track the exact location but can also compute velocity and time. The positions can even be computed in three-dimensional views with the help of four GPS satellite signals. The Space Segment of the Global Positioning System consists of 27 Earth-orbiting GPS satellites. There are 24 operational and 3 extra (in case one fails) satellites that move round the Earth each 12 hours and send radio signals from space that are received by the GPS receiver.The control of the Positioning System consists of different tracking stations that are located across the globe. These monitoring stations help in tracking signals from the GPS satellites that are continuously orbiting the earth. Space vehicles transmit microwave carrier signals. The users of Global Positioning Systems have GPS receivers that convert these satellite signals so that one can estimate the actual position, velocity and time.
Who does an GPS(global positioning system) works?
GPS satellites have a fixed position in sky. These satellites contain an exact clock and send their position and a time stamp. Your receiver measures the time difference between these signals. With this information You can calculate the different distances to these known satellite positions (at least 4 of 24). Now you have to use mathematics and you will get your position.
How does Global Positioning System work?
Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations so that these repeating signals are transmitted at the same instant. The signals, moving at the speed of light, arrive at a GPS receiver at slightly different times because some satellites are farther away than others. The distance to the GPS satellites can be determined by estimating the amount of time it takes for their signals to reach the receiver. When the receiver estimates the distance to at least four GPS satellites, it can calculate its position in three dimensions. There are at least 24 operational GPS satellites at all times. The satellites, operated by the U.S. Air Force, orbit with a period of 12 hours. Ground stations are used to precisely track each satellite's orbit. Determining Position A GPS receiver "knows" the location of the satellites, because that information is included in satellite transmissions. By estimating how far away a satellite is, the receiver also "knows" it is located somewhere on the surface of an imaginary sphere centered at the satellite. It then determines the sizes of several spheres, one for each satellite. The receiver is located where these spheres intersect. Bottom Line: u need at least 3 satellites to get the 3 unknowns X, Y, Z of ur location
What is the global positioning system (GPS), and how does GPS allow scientists to measure the rate of motion o?
GPS is a set of Satellites in Earth Orbit that transmit Radio Signals to a Receiver on Earth. The GPS Unit receives signals from several satellites at once and through a special process can pin point it's exact location, altitude and direction and speed of movement. That is the Simple Explanation for a more technical explanation: http://www.nasm.si.edu/gps/work.html
The Global Positioning System (GPS) was originally designed for use by who/what?
By the US military.
For the Global Positioning System (GPS) to work, at any given time there must be?
four satellites minimum visible to the receiver.
How to find out Global position (GPS)?
How to find out Global position (GPS)? In the earth explain clearly Please! Can anyone help with the following questions about topographic maps!! Thank you all for helping me. 1) Can a contour line on a topographic map connect a point with an elevation of 100 feet? Explain why or why not. 2)On a topographic map, how would you show an island in the ocean with an elevation of 80 feet if the contour line is 10 feet? 3) How could a person lost at sea use Global Positioning System ( GPS) to find out where he or she is? 4)If you were making a topographic map, how would you show a steep cliff? 5) Why do you think gentle slopes are shown with more widely spaced lines than steep slopes sre? 6)Why do you think one contour line never crosses another contour line? last one! 7) On which map would contour lines probably be easier to read, a topographic map of a city or a topographic map of a wilderness area? Explain me clearly.
What does the Global Positioning System allow people to determine anywhere in the world?
That would be it. :-) It's also great for finding tupperware in the woods.
