Before revision: Control point marker placed by the US Coast and Geodetic Survey Example of triangle network and its application in chartography Worldwide BC-4 camera geometric satellite triangulation network Typical GNSS reference station International Terrestrial Reference System (ITRF) reference stations Network of reference stations used by Austrian Positioning Service (APOS) A geodetic control network (also geodetic network, reference network, control point network, or control network) is a network, often of triangles, which are measured precisely by techniques of terrestrial surveying or by satellite geodesy.
