Satellite station definition surveying.
Modern ground based survey methods involve detailed survey which provides three space co ordinates for surveyed points to a high level of accuracy.
Such surveys are conducted for a location or region and referenced to the earth global co ordinate system with.

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.
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.
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.
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.
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.
Baseline measurements for classical triangulation the basic survey method that consists of accurately measuring a base line and computing other locations by angle measurement are therefore reduced to sea level length to start computations and.
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.
A land surveying professional is called a land surveyor these points are usually on the surface of the earth and they are often used to establish maps and boundaries for ownership locations such as.
The instruments are operated by surveyors who process the raw results to create survey location maps for the subject of the survey.

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