Active positioning data is generated by positioning the mobile subscriber through the device- or network-centric methods, as well as via satellite (i.e. Global Positioning System, GPS). These methods are used either for providing location-based services or in response to national regulations requiring the capture of highly accurate location data (e.g. for rescue and police purposes). Active positioning capabilities are common in the systems of operators in developing economies and are often used merely on a case-by-case basis. Common methods of active positioning include cellular triangulation or assisted GPS.
