GPS e GNSS na Topografia: Como Funciona o Posicionamento por Satélite (Explicação Completa)

In this comprehensive lesson from the Engelmax Topography channel, you will clearly and objectively understand how satellite positioning works in modern surveying. Many professionals use GNSS receivers daily in topographic surveys, but few truly understand all the concepts involved in calculating the coordinates obtained in the field. In this video lesson, we explain everything from the fundamental principles of GPS and GNSS to the positioning techniques used in professional practice. You will learn: • What GPS is and what GNSS means • Difference between GPS, GLONASS, Galileo, and BeiDou systems • How satellites determine position on Earth • The concept of trilateration in positioning • How the receiver calculates coordinates • What pseudoranges are • Why at least four satellites are needed • Main sources of error in positioning • Positioning techniques used in surveying • Difference between static, post-processed, and RTK positioning • Coordinate systems used in GNSS surveys The use of GPS/GNSS has revolutionized surveying, allowing for much faster and more accurate surveys compared to traditional methods. Understanding these concepts is essential for anyone who works or wants to work with surveying, land surveying, georeferencing, and engineering. If you want to master the fundamentals of satellite positioning and improve your understanding of the equipment used in the field, this lesson is for you.
