An aircraft landing and/or taxiing system has a plurality of landing zone, runway, and/or taxiway lights capable of receiving information signals and transmitting optically signals representative of the information signals. A processing system for providing the information signals to the plurality of lights is also used. The system also comprises a sensor tuned to receive light of a specific range of wavelengths, the light being emitted from the lights. Also, a processing system coupled to the sensor and configured with software to interpret signals received by the sensor is used. Program code runs on the processing system. The program code is configured to determine the location of an aircraft on the taxiway based on the light signal received from one or more of the taxiway lights. Also, the aircraft landing and/or taxiing system utilizes modulated lights to provide information pertinent to aircraft landing and/or taxiing operations.
