What we have learnt

  • GNSS and Total Stations enhance precision and efficiency in surveying.
  • Total Stations are versatile tools capable of a wide range of measurements, including distance, angles, and 3D coordinates.
  • Calibration is essential for ensuring the accuracy of Total Stations and must be performed regularly to mitigate measurement errors.

Key Concepts

-- Total Station
A surveying instrument that combines the functions of a theodolite and an electronic distance meter to measure angles and distances.
-- GNSS
Global Navigation Satellite System, which uses satellites to provide accurate position, velocity, and time information anywhere on Earth.
-- Calibration
The process of adjusting and verifying the accuracy of the Total Station's measurements in relation to known standards.
-- Trilateration
A method used to determine the position of a point by measuring distances from that point to three or more known points.
-- Atmospheric Errors
Errors in GNSS measurements due to changes in atmospheric conditions, requiring corrections to be applied for accurate positioning.
