Abstract (en)
[origin: WO9805977A1] A process and a system for location of objects, mainly aircraft (7), where at least three receiving stations (1 to 3) spaced apart from each other on places with known co-ordinates are received signals (6) emitted from object's emitter, these signals (6) are retransmitted in real-time from all receiving stations (1 to 3) into one processing station (5) placed on place with known co-ordinates, in which selection and mutual association of signals emitted by individual emitters and measurements of time delay ( tau ij) between signals belonging to individual emitter which come from individual receiving stations (1 to 3) is carried out and where from measured time delays ( tau ij) and known locations of receiving stations (1 to 3) and processing station (5) location of object emitting received signals (6) is evaluated.
