1. A method for configuring a local positioning system, the method comprising:

  • orienting a survey antenna coextensively with a primary beacon associated with a work area;

    transmitting a first transmission signal from the survey antenna;

    receiving the first transmission at one or more secondary beacons associated with the work area;

    determining first elapsed times from the transmission of the first transmission signal to at least the arrival at respective corresponding secondary beacons, each of the first elapsed times falling within a filtering time window to reduce multi-path error; and

    converting the first elapsed times into a first position in at least two spatial dimensions for the primary beacon.
