GEO-RTK is a real-time precise positioning service via network of permanent GNSS stations, which provide accuracy in absolute position within 2 centimeters, anywhere, anytime, with only single receiver and network data corrections. 

Data obtained in the DGPS mode can be used for:

  • Geodetic/cadastral surveying. Construction of buildings, roads and installations.
  • Building and maintenance of oil and gas pipelines. Machine guidance and management. Utility sector.

The process of surveying:

  • The reference network stations continuously receive data from satellites and forward them to a central server with data processing software installed (Trimble GPS NET).
  • The software decides the ambiguity in the network, generates corrections and send them to rovers.
  • Rovers connect to the server via radio, GSM or Internet connection to obtain real-time corrections and calculates the position within few centimeters, using the algorithm set out in the software.
