Real-time location information system using multiple positioning technologies

摘要

Systems, methods and computer program products for tracking objects in an area of interest are described. According to an embodiment, an object is tracked as follows. First position information relating to the object is received from a first sensor and translated to a coordinate system of a map. The object is displayed on the map in accordance with the translated first position information. Second position information relating to the object is received from a second sensor, where the second sensor is based on a second positioning technology different from the first positioning technology. The second position information is translated to the coordinate system of the map, and the object is displayed on the map in accordance with the translated second position information. In an embodiment, other information relating to the object is also received from sensors.
