NEW SURVEYING INSTRUMENTS

RTK — Real Time Kinematics is another method used to achieve precise positioning. It uses two GPS receivers at the same time. "The user needs to be near a reference station, which acts as a control point, and then the signal received from the satellites is corrected and transmitted to a second mobile unit for data collection. "This is a technique commonly used in surveying because of its high precision in controlled environments. -The RTK technique can be used for distances of up to 10 or 20 km.

They are also now widely used in surveying. Laser scanning is a relatively new technology and has been used as a precise survey instrument only since 1998. It is now commonly used in industry as it very accurate measurements in environments. It is particularly useful in architecture when designing the inside of buildings. The scan can be set up at various positions inside a room or a building in order to make a complete 3D model of the space available. "These drawings can then be used to create 2D architectural drawings, 3D computer models, and final survey documents. Despite drones (unmanned aircraft systems) have been on the market for some time, until now they have not been used much in surveying, but things are about to change. With the latest drone models that are now more practical, less expensive and more lightweight, drones will soon become an integral part of surveying.
