    摘要: A light system for defining a line of approach uses light sources arranged in an array. The light sources are arranged such that they define a primary field-of-view (FOV) from which all of the light sources are visible. Less than all of the light sources are visible from positions outside of the primary FOV. The light sources are further divided into sections with each section having a portion of the light sources associated therewith. The light sources are controlled in accordance with cyclical on/off sequences. A primary waveform of light energy is defined by the cyclical on/off sequence visible from within the primary FOV. A plurality of secondary waveforms of light energy are defined by the cyclical on/off sequences visible from positions outside of the primary FOV.

    摘要: A system provides guidance to a vehicle on an approach to a position. A guidance transmitter stationed at the position includes light sources arranged in an array and a controller coupled to the light sources. The array defines a primary field-of-view (FOV) from which all light sources are visible. The light sources are divided into a plurality of sections with each section having a portion of the light sources associated therewith. Operation of each section of light sources is governed by the controller in accordance with unique cyclical on/off sequences. A primary waveform of light energy is defined by a composite of the cyclical on/off sequences visible from within the primary FOV. A plurality of secondary waveforms of light energy are defined by the cyclical on/off sequences visible from positions outside of the primary FOV. A guidance receiver mounted on a vehicle traveling towards the position of the guidance transmitter includes (i) sensor(s) for sensing light energy generated by those light sources visible thereto, (ii) a database for storing calibration waveforms indicative of corresponding guidance correction signals, and (iii) a processor for determining which one of the calibration waveforms matches or is closest to the sensed one of the primary waveform and secondary waveforms. The guidance correction signal associated with the matching calibration waveform can be used to control navigation of the vehicle.

    摘要: A method of guiding a vehicle to a position is provided. Light sources arranged in an array are placed at a position with the light sources defining a primary field-of-view (FOV) from which all of the light sources are visible. Less than all of the light sources are visible from positions outside of the primary FOV. The light sources are divided into sections with each section having a portion of the light sources associated therewith. The light sources are operated in accordance with cyclical on/off sequences so that a primary waveform of light energy is defined by the cyclical on/off sequence visible from within the primary FOV and secondary waveforms of light energy are defined by the cyclical on/off sequences visible from positions outside of the primary FOV. The light energy generated by the light sources is sensed by an approaching navigable vehicle. Based on the position of the vehicle, one of the primary waveform and the plurality of secondary waveforms is sensed. A database on the vehicle stores calibration waveforms indicative of guidance correction signals that can be used to control navigation of the vehicle. The calibration waveform that is closest to the primary and secondary waveforms so-sensed is indicative of the guidance correction signal.
