CST Level 1 Land Surveyor Certification Practice

GNSS stands for Global Navigation Satellite System, which refers to a system that provides geolocation and time information to a GPS receiver anywhere on Earth where there is an unobstructed line of sight to four or more satellites. The term encompasses various satellite systems, including the American GPS, Russian GLONASS, European Galileo, and Chinese BeiDou.

The term "Global" emphasizes the worldwide availability and coverage of the system, while "Navigation" highlights its primary purpose: aiding in determining position, navigation, and timing. Understanding GNSS is crucial for land surveying as it plays a vital role in accurately determining geographic locations and heights over large areas, making it an essential tool in modern surveying practices.

Other options focus on variations in terminology that do not accurately describe the established term used within the surveying and geospatial community. These incorrect terms either modify the fundamental meaning or introduce concepts not recognized in standard geospatial terminology.
