locating engine
A locating engine (sometimes referred as a positioning engine) is the computational engine behind real-time locating systems (RTLS) and navigation support system. A locating engine combines algorithms of geometry or topography with algorithms of filtering to calculate a best estimate for objects or people, and to do so in real-time. The locating engine is the implementation of the algorithms for determining the equations of coordinates from inverting matrices of distances.
Many different approaches can be used in creating a location engine, but all modern systems are based on multilateration or triangulation and least squares.
== Topology and topography ==
Location information is never obtained in a single step. A location may be described through relative positional data, absolute positional data or any intermediate information for obtaining such data. Eventual descriptions are topographical, mostly referring to a terrain map or a building plan. Locating requires more than topological descriptions, which for instance only include neighbourhoods and hop counts, as is the case of communications networks. The topological description is however a prerequisite for operating some types of locating engines in order to obtain a topographical determination afterward.
