Geodetic surveys involve such extensive areas that allowance must be made for the earth s curvature.
Satellite station definition surveying.
Satellite surveying is a form of land survey that uses location information provided by the gps satellite system to track the location of each reference point.

In surveying free stationing also known as resection is a method of determining a location of one unknown point in relation to known points.
There is a zero point of reference called a total station the instrument can be freely positioned so that all survey points are at a suitable sight from the instrument.
In surveying however greater accuracy is required and this is attainable because the observer and the instrument are stationary on the ground instead of in a ship or aircraft that is not only moving but also.
Satellite surveying is a form of land survey that uses location information provided by the gps satellite system to track the location of each reference point.
Modern surveying gps equipment and recent smart phones are now able to use multiple systems thus increasing the number of satellites visible at any one time.
Surveying or land surveying is the technique profession art and science of determining the terrestrial or three dimensional positions of points and the distances and angles between them.
Surveying surveying global positioning.
The instruments are operated by surveyors who process the raw results to create survey location maps for the subject of the survey.
However it hasn t entirely replaced surveying field instruments such as the theodolite electronic distance meter or the more modern total station due to the cost of the technology and the need for gps to be able to see the satellites therefore restricting its use near trees and tall buildings.
Since the introduction of gps many other countries have developed similar satellite based navigation systems such as the russian glonass chinese beidou and european galelio.

The techniques used to establish the positions of reference points within an area to be mapped are similar to those used in navigation.
