[loh-keyt, loh-keyt]
Locating is a process used to determine the location of one position relative to other defined positions. Locating is applied for location metering of moving objects and is not to be confused with surveying, which is utilized in reference to stationary terrestrial objects.

Classical passive locating systems operate with a mesh of transmitters and unilateral reception, as GPS, GLONASS, Galileo positioning system and GSM cellnet locating. Further development has led to cooperative systems, where both positions are equipped with respective apparatus and thus provide bilateral measuring.

Metering results are obtained from ranging. The condition for unambiguousness on a line is 2 meterings, in a plane 3 meterings and in a space 4 meterings.

Combining several metering results in a time sequence leads to tracking and tracing.

Locating in real time

Obtaining locations in real time, i.e. with no delay between appearance in a location and availability of knowledge about the very same location, is Real Time Locating.

Locating engine

A locating engine is a computing construct that enables the computing of proper coordinates of objects in real time locating from noised-disturbed and motion-biased sets of longitudinal data.
