What Is Satellite Station In Surveying

Satellite survey remote sensing utilise satellite imagery which have been processed using commercial geographic information system software.

What is satellite station in surveying.

Satellite station to secure well conditioned triangles or to have good visibility objects such as chimneys church spires flat poles towers lighthouse etc are selectedastriangulationstations. 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. Gps stands for global positioning system gps is a highly accurate navigation system using signals from satellites to determine a location on the earth s surface irrespective of weather conditions. The instrument can be freely positioned so that all survey points are at a suitable sight from the instrument.

A radio signal is transmitted at a steady frequency by the satellite but a stationary observer detects a higher frequency as the satellite approaches and a lower one as it recedes. There is a zero point of reference called a total station. How many feet are in surveying. Three space co ordinate maps are generated with an accuracy determined by the datum position accuracy and optical resolution of the satellite platform.

The gps is a satellite based navigation system made up of a network of 24 satellites placed into orbit by the u s. Such stations can but it is not. A total station is used for carrying out goniometric measurements concurrently with measurement of lengths. A total station is an electronic optical instrument used in modern surveying and building construction that uses electronic transit theodolite in conjunction with electronic distance meter edm it is also integrated with microprocessor electronic data collector and storage system.

Gps works in any weather conditions anywhere in the world 24 hours a day. 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. It is dependent on gps satellites high above the earth which transmit signals containing the time and location of the satellite. Gps was originally intended for military applications but in the 1980s the government made the system available for civilian use.

A total station is an electronic optical tool utilized in modern surveying.
