Systems and methods for geographic positioning using radio spectrum signatures

A device comprising:

• instructions for accessing a radio signature lookup table, said radio signature lookup table comprising a plurality of reference radio signatures that collectively represent a frequency spectrum, each reference radio signature in said plurality of reference radio signatures associated with a global position;
• a radio signature measurement model for localizing a geographic position of a device, the radio signature measurement model comprising instructions for obtaining a current radio signature, wherein said current radio signature comprises a plurality of measured signal qualities, each measured signal quality in said plurality of measured signal qualities corresponding to a portion of said frequency spectrum;
• and
• a radio signature comparison module comprising instructions for comparing said current radio signature to said plurality of reference radio signatures.

A radio comprising:

• means for accessing a radio signature lookup table, said radio signature lookup table comprising a plurality of reference radio signatures, each reference radio signature in said plurality of reference radio signatures associated with a global position;
• means for localizing a geographic position of the radio, the radio signature measurement model comprising instructions for obtaining a current radio signature, wherein said current radio signature comprises a plurality of measured signal qualities that collectively represent a frequency spectrum, each measured signal quality in said plurality of measured signal qualities corresponding to a portion of said frequency spectrum;
• and
• means for comparing said current radio signature to said plurality of reference radio signatures.
