Abstract :
Geolocation with ultra wide band signals has seen much progress in recent years. Nevertheless, the use of narrow band signals hasn´t been studied rigorously despite its advantages that we present in this paper. We study the case of using low power carrier signal from the ISM [Industrial, Scientific & Medical] radio bands, where each user that have to be geolocated accesses to a statistical frequency from the band [868, 870 MHz]. The modulating signal is a square of 100Hz frequency and the Method used for geolocation is TDOA.
