Synchronization of optical signaling beacons |
摘要 |
An arbitrary number of signaling beacons are synchronized simultaneously and automatically by a received modulated control signal in accordance with an arbitrary communication protocol over a communication link which may be separate from or superimposed upon a perceptible signal periodically provided from signaling beacons. The periodic perceptible signal may be stabilized using a crystal oscillator or an external transmitted signal such as a global positioning system (GPS) signal and synchronization thus maintained for extended periods of time even when the synchronization communication link is not available. Interference is substantially prevented by the communication protocol while supporting the provision of any desired beacon control functions.
