A location system for identifying locations of emitters in a cellular telephone service area. Searching identifies active emitters in the service area to find the coarse areas in which active emitters are located, using selection criteria to designate one or more of the active emitters as selected emitters. Emitter signals are measured with a plurality of sensors, each sensor at a different location. Groups of the sensors are tasked, one group of tasked sensors for each corresponding selected emitter. Each tasked sensor takes a measurement on an emitter signal transmitted by the corresponding selected emitter. The measurements are processed to determine the location of each selected emitter based on the measurements from the group of tasked sensors.
