Local positioning system

A local positioning system (LPS), comprising:

• a plurality of local position tracking devices, the plurality of the local position tracking devices further comprising:
• a plurality of clocks, wherein at least some of the clocks are synchronized;
• and
• at least one transmitter configured to transmit signals over time synchronized to one or more of the clocks, each of the signals associated with a time that the signal was transmitted;
• and
• at least one receiver configured to receive the signals over time synchronized to one or more of the clocks, each of the signals further associated with a time that the signal was received by the receiver;
• and
• a processor operatively coupled to at least one of the plurality of the local position tracking devices, wherein:
• the processor is configured to receive one or more representations of at least a part of the living body comprising one or more representations of one or more of the local position tracking devices relative to at least the part of the living body;
• the processor is configured to obtain a further representation of the at least the part of the living body based on the transmission time for each of the signals, the receipt times for each of the signals, and one or more of the representations for the local positioning tracking devices;
• and
• the processor is further configured to provide output comprising at least one of one or more of the representations of the at least one part of the living body, one or more of the further representations as at least one of living-perceptible data and computer-readable data, one or more of the transmission times, and one or more of the receipt times.
