摘要： A first location determining receiver (16) determines a first location estimate of a vehicle. The first location determining receiver is associated with satellite beacons. A second location determining receiver (18) determines a second location estimate of a vehicle. The second location determining receiver is exclusively associated with terrestrial beacons (12, 14). A selector (20) selects the first location estimate of the vehicle as a preferential location in accordance with an initialization scheme for the vehicle in a work area. A filtering module (24) applies a first weight to a first location and a second weight to the second location to derive a weighted estimate as the preferential location upon satisfactory completion of the initialization scheme.

摘要： A method and system for determining the position of a vehicle comprises a transmitter or transceiver for transmitting a transmission signal from a vehicle to beacons associated with the work area. Each beacon is associated with a corresponding transceiver or receiver for receiving the transmission signal. A data processor at a beacon, the vehicle or both determines an elapsed time including at least one of a first propagation duration and a second propagation duration. The first propagation duration refers to a propagation time of the transmission signal from the vehicle to the particular beacon; the second propagation duration refers to a propagation time of a return signal from the particular beacon to the vehicle. A compensator compensates for one or more of the following associated with at least one of the transmitter and the particular beacon: bias delay, noise, and measurement error. A data processor processes the elapsed times (for paths between vehicles and beacons) into corresponding position curves or temporal curves to estimate a position of a vehicle at a confluence or intersection of the position curves or temporal curves.

摘要： A transmitter (14) at a lead vehicle (10) transmits a first transmission signal toward a first beacon (30) and a second beacon (34) associated with a following vehicle (26). A data processor (16) or estimator (18) determines a first propagation time associated with the first transmission and the first beacon (30) and a second propagation time associated with the first transmission and the second beacon (34). A vehicle controller (41) controls a heading of the following vehicle (26) to maintain a first distance substantially equal to a second distance (i.e., first propagation time substantially equal to a second propagation time) or a first distance that deviates from the second distance by a predetermined maximum amount.

摘要： A method for configuring a local positioning system comprises orienting a survey antenna (21) coextensively with a primary beacon (111) associated with a work area. A transmitter (22) or transceiver transmits a first transmission signal from the survey antenna (21). A receiver or transceiver (14, 18) receives the first transmission at one or more secondary beacons (113) associated with the work area. A data processor (24) determines first elapsed times from the transmission time of the first transmission signal to at least the arrival time at respective corresponding secondary beacons (113). 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 (111).
