504 results about "Control network" patented technology

In geodesy and surveying a control network or simply control, is a set of reference-points of known geospatial coordinates. The higher-order control points are normally defined in both space and time using global or space techniques, and are used for "lower-order" points to be tied into. The lower-order control points are normally used for engineering, construction and navigation. The scientific discipline that deals with the establishing of coordinates of points in a high-order control network is called geodesy, and the technical discipline that does the same for points in a low-order control network is called surveying. Classically, a control is divided into horizontal and vertical controls, however with the advent of satellite navigation systems, GPS in particular, this division is becoming obsolete.
