Abstract
A method for configuring a local positioning system comprises orienting a survey antenna coextensively with a primary beacon associated with a work area. A transmitter or transceiver transmits a first transmission signal from the survey antenna. A receiver or transceiver receives the first transmission at one or more secondary beacons associated with the work area. A data processor determines first elapsed times from the transmission time of the first transmission signal to at least the arrival time at respective corresponding secondary beacons. Each of the first elapsed times falls within a filtering time window, or satisfies an edge timing criteria of the coded signal, or both to reduce multi-path error. The first elapsed times are converted into a first position in at least two spatial dimensions for the primary beacon.
