1. A system for determining a location of a receiver, the system comprising:

  • one or more transmitters configured to transmit one or more radio signals, respectively;

    a receiver communicatively linked to the transmitters, the receiver comprising a clock, a memory, and a processor, wherein the processor is configured to execute computer-executable instructions stored in the memory, the execution of which make the receiver operable to;

    receive the radio signals;

    capture the radio signals as one or more received signal waveform, respectively;

    store the received signal waveforms in the memory;

    calculate one or more virtual transmitted waveforms based upon the received signal waveforms, respectively; and

    determine, based upon the received signal waveforms and the virtual transmitted waveforms, a position of the receiver relative to the transmitters.
