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.
