1. A localization system, comprising:

  • a first anchor comprising a first clock and a first antenna, wherein the first anchor is configured to emit a first timestampable localization signal from the first antenna at a first time based on a clock signal of the first clock, wherein the first timestampable localization signal comprises a preamble followed by a payload; and

    a second anchor comprising a second clock and a second antenna, wherein the second anchor is configured to emit a second timestampable localization signal from the second antenna at a second time based on a clock signal of the second clock, wherein;

    the first clock and second clock are synchronized in time;

    the second timestampable localization signal comprises a preamble followed by a payload;

    the emission of the second timestampable localization signal partially overlaps with the emission of the first timestampable localization signal such that the second timestampable localization signal does not overlap the preamble of the first timestampable localization signal; and

    the first timestampable localization signal and the second timestampable localization signal can be received within a common region.
