About this chapter

The chapter discusses the integration of GNSS and Total Station technologies in surveying, highlighting their increasing efficiency and accuracy in measurement tasks. It examines the applications, advantages, and limitations of Total Stations, along with calibration processes, error sources, and the functionality of global positioning systems (GPS). The evolution and impact of GNSS on various fields are emphasized, showcasing significant advancements in navigation capabilities.

Learning objectives

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.
