FIGS. 14A and 14B are a block diagram of a transmitter configured to transmit four pseudo-noise codes using diversity polarization, and a chart indicating the polarization of the output electromagnetic radiation, respectively, according to an example embodiment.

FIGS. 15A and 15B are a block diagram of a receiver configured to receive and demodulate four pseudo-noise codes using diversity polarization, and a chart indicating the overall polarization of the received electromagnetic radiation, respectively, according to an example embodiment.

Overview

Described herein is a method that, according to one aspect, comprises transmitting a digital code from a transmitter to a receiver. This aspect further comprises transmitting information 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. According to example embodiments, the first information may include a first navigational code and the second information may include a second navigational code.
