Abstract
A method and apparatus for sending timing information using an optical signal. A first electrical signal comprising a pseudorandom binary sequence is generated. The first electrical signal comprising the pseudorandom binary sequence is modulated with a second electrical signal to form a modulated electrical signal. The second electrical signal includes timing data in a format used for global positioning systems. An optical carrier signal is modulated with the modulated electrical signal to form the optical signal using an optical transmitter.
