1. A method for modulation of a variable binary offset carrier (VBOC) having a discrete time-variant frequency, the method comprising:
generating navigation message data;
generating a carrier;
generating a VBOC subcarrier;
generating a pseudo-random code;
synthesizing the pseudo-random code and the VBOC subcarrier; and
synthesizing a synthesized signal of the pseudo-random code and the VBOC subcarrier, the carrier, and the navigation message data.
