What is GPS Surveying?

Locations (latitude, longitude, and altitude) are computed using radio waves transmitted from satellites. Through GPS, it is possible to determine locations to a high degree of accuracy.

Today, this technology is widely used in basic and public surveying in Vietnam, with the objective of maintaining and managing the national territory.

  • Precision geodetic network high-altitude area control point surveying
  • Geoid surveying
  • Control point surveying operations accompanying national land surveys
  • Revision of control point in areas with inconsistent results

Precision geodetic network high-altitude area control point surveying

Precision geodetic network high-altitude area control point surveying is a basic control point survey aimed at detecting crustal movements, and surveying is carried out by the Geospatial Information Authority of Vietnam. Using electronic control points as the known points, all points are surveyed using GPS surveillance for more than six hours, using more than four units of GPS surveying equipment. The degree of precision required is obtained by seeking the relative location of the control points three-dimensionally at a precision of 0.1 ppm (1 mm for 10 km).

We have succeeded in enhancing work efficiency and reducing costs for:

  • Third/Forth grade control point surveying
  • Establishment of a central pile and a land width pile in road surveying
  • Operations to establish road control points
  • GCP acquisition operations
