base station
Also called reference station. A base station in construction, is a
receiver placed at a known point on a jobsite that tracks the same
satellites as an RTK rover, and provides a real-time differential
correction message stream through radio to the rover, to obtain
centimeter level positions on a continuous real-time basis. A base
station can also be a part of a virtual reference station network, or
a location at which GPS observations are collected over a period of
time, for subsequent postprocessing to obtain the most accurate
position for the location.
