DGPS/TS Survey
DGPS uses a network of fixed ground-based reference stations to broadcast the difference between the positions indicated by the GPS satellite system and known fixed positions. DGPS is an enhancement to Global Positioning System that provides improved location accuracy. It can give up to subcentimeter readings. Total station is an optical instrument commonly used in surveying. It is useful for measuring horizontal angles, vertical angles and distance, it does this by analysing the slope between itself and a specific point The basic properties are unsurpassed range, speed and accuracy of measurements. Total stations are developed in view of the maximal convenience of work of the user.
