Definition

A survey performed with positioning tools that use the Global Navigation Satellite System (GNSS) in order to establish coordinates and determine boundaries.

Description

GNSS-based technologies may be used in conjunction with traditional land survey methods (and permanent survey marks) or independently. GNSS technology may be used to establish or verify the coordinates of survey marks used in traditional surveying. GNSS receivers may be used to establish points without reference to traditional survey marks. A higher accuracy for standalone GNSS positioning tools is achieved using GNSS signals together with CORS (Continuously Operating Reference Stations) to establish land survey data associated with the geodetic datum.
