Abstract
A method includes transmitting a digital code from a transmitter to a receiver. Information is transmitted via electromagnetic waves from the transmitter to the receiver. The transmission of the information includes transmitting a first portion of the information using electromagnetic waves with a first polarization in response to a first value of the digital code, and transmitting a second portion of the information using electromagnetic waves of a second polarization in response to a second value of the digital code. The first information may include a first navigational code and the second information may include a second navigational code.
