GPS SURVEY

GPSย  SURVEY

The Global Positioning System (GPS) is a satellite-based positioning system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS satellites 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 exact position of them. 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. With the distance measurements from a few more satellites, the receiver can determine its position with centimeter accuracy.ย

  • TOTALย  STATIONย  SURVEY

    A total station is an optical instrument used in modern surveying. It is a combination of an electronic theodolite (transit), an electronic distance meter (EDM) and software running on an external computer known as data collector. A total station allows the surveyor to store all information he needs to establish a setting out and can store all information taken from site as existing features, original ground levels, road edges, etc.ย 
    Also the remote measurements are facilitated by the total station where a direct access is not available. For example the height of street light poles, ground clearance of overhead power lines, etc.

  • Ron Thanks for correction.

  • Government Professional

    Basically correct, except for the use of the word "triangulation".ย  It is "trilateration" that should be used.ย  Triangulation is the determination of a location by the measurement of angles.ย  Trilateration is the determination of a location by measurement of lengths of lines.ย  GPS measures line lengths from satellites to receiver.
