GNSS data collection
This document discusses different GNSS positioning techniques. GNSS point positioning involves collecting location data from a stationary point for an extended period of time to determine its coordinates with 5-10 meter accuracy. Kinematic GNSS positioning is used to determine the position of moving objects with 10-100 meter accuracy by collecting data throughout its movement. Differential positioning uses corrections from a base station to improve the remote receiver's position accuracy relative to the base station.
