GNSS (Global Navigation Satellite System)

GNSS (Global Navigation Satellite System) surveying is a technique that uses satellite signals to determine the location of a point on Earth. It’s also known as GPS surveying.

How it works:
  • A GNSS receiver, often a handheld device, collects signals from satellites
  • The receiver uses data from multiple satellites to calculate the position of the point
Benefits:
  • Accuracy: GNSS is more accurate than other methods
  • Speed: GNSS is fast, reducing the time it takes to get results
  • Safety: GNSS can increase safety
  • Ease of use: GNSS is easier to use than other methods
Types of GNSS surveys: 
  • Static surveys: A type of GNSS survey technique 
  • Kinematic surveys: A type of GNSS survey technique 
  • Real-time kinematic (RTK) GNSS: A type of GNSS that uses real-time corrections from reference stations to achieve a higher level of accuracy
