What is the GPS Surveying and it’s Methods
                     What is the GPS 
Surveying and it’s 
Methods?
 GPS Surveying is a method of measuring a Particular Land area with the 
help of Digital Data Collecting Equipment from a Group of Satellites.
 GPS (Global Positioning System) plays an Important Role in Land 
Surveying Equipment to get accurate Measurement from a particular 
Height, Location and Distance Quickly. It just needs a Clear sky to get the 
signals from a group of satellites that provides High-level Combined 
Accuracy results from once place which is far better than Manual 
Equipment and techniques. With daily new innovation in Land Surveying 
Industries, it’s better to hire it from Authentic GPS Providers in UAE 
instead of buying it.
 Different types of GPS land survey equipment are used to get different 
measurements; there are three popular methods of GPS measurement 
used by most of the surveyors:
Static GPS Baseline:
 This technique is used to get the 
proper coordinates for survey 
points by concurrently recording 
GPS Observations from both 
known and unknown points for a 
minimum of 20 minutes. After that 
data will be processed to get the 5 
mm accuracy coordinates.
RTK Observations
 In the Real-Time Kinematic 
method there are using two 
different receivers, one of them 
remains the same at one 
location while another is 
moving between two different 
points. By using a Radio link the 
positions of the rover station 
can be calculated within a few 
seconds. Just make sure the 
level of accuracy baseline 
measurements as long as they 
are within 10km of the base 
station.
CORS Method
 In this method, a single GPS 
Receiver is permanently installed 
at a fixed location as a starting 
point for any GPS Measurement in 
that Area. GPS Equipment 
collecting all the field data and 
combine it with Continuously 
Operating Reference Stations to 
get the exact calculates positions.
