geodetic

1. Introduction to Geodetic Survey:
Geodesy’ is the branch of physics that deals with the study
of accurate measurement of earth’s geography, mass
distribution, orientation, etc.
Geodesy using GPS(Global Positioning System) through
satellite for navigation purposes and to measure the
position of points in terrestrial base stations (Simply
measures earth’s Geodynamical phenomena during
surveying for some projects) is known as Geodetic survey.
The accuracy and precision of the geodetic survey depend
upon the observed values in the field.
GPS traces the position correctly with the help of satellites.
These satellites are also used by scientists to monitor plate
tectonics motions, earthquakes, volcanic hazards, landslide
hazards, groundwater pressure, etc.
