Patent ID: 8718918

Claim:
A method, comprising: detecting, at a signal detecting unit associated with a first vehicle, one or more signals received from one or more signal sources, the signal detecting unit comprising one or more signal sensors and one or more computer processors; determining, by the one or more computer processors, a set of time values based on arrival times of the one or more signals; generating, by the one or more computer processors, a set of distance expressions, wherein each distance expression corresponds to a distance between one of the one or more signal sensors and one of the one or more signal sources; generating, by the one or more computer processors, a set of distance equations based at least in part on the set of time values and the set of distance expressions; and solving, by the one or more computer processors, the set of distance equations to determine a first position or a second position, wherein the first position represents a position associated with the first vehicle within a coordinate system defined in relation to the one or more signal sources, and the second position represents a position associated with the one or more signal sources within a coordinate system defined in relation to the first vehicle.
