In a device for location positioning, and more particularly, in a system for identifying an environmental source emitting a base frequency and waveform signal, a sensor ( 101 ) records an environmental source ( 105 ) emitting a base frequency and waveform signal, the signal being amplified ( 102 ), digitized ( 103 ), processed and compared ( 104 ) with a stored unique waveform characteristic. On the basis of the comparison result(s), location positioning and/or a device orientation may be determined. |
