In a geo-location system, the location of an object in space is determined by transmitting polarized signals towards the object. To prevent erroneous determinations due to signals which reach the object after reflection the transmitted signals are polarized. The receiver at the object includes a cross-polarization discriminator and accepts only directly transmitted signals and not reflected signals which have been cross-polarized by the reflection. The transmitted signals may be ultra-wide band signals which can penetrate into buildings. An object whose location can thus be determined can also transmit polarized signals to another object which can not be reached by signals from the original transmitter. Further the ultra-wide band signals may utilize transmission in discontinuous frequency bands to avoid interference with existing systems.
