Claim:
1. A method for identifying positions within a geolocation system comprising: transmitting an interrogation signal from a vehicle; detecting the interrogation signal by a luminaire associate within at least one smart street light, wherein the smart street light has knowledge of a predetermined power spectral density shape of the interrogation signal transmitted by the vehicle; sending a response from the smart street light; receiving the response by the vehicle; and measuring outputs of a plurality of bandpass filters employed with the luminaire associate and thereby estimating a position of the vehicle within the geolocation system from the interrogation signal detected by the luminaire associate.
