1. A method of enhanced GPS receiving by mitigating interference in reception of global positioning system (GPS) signals, the method comprising:

  • receiving, from a first antenna, a first signal comprising a desired signal component S1 and a jammer signal component J1;

    receiving, from a second antenna, a second signal comprising a desired signal component S2 and a jammer signal component J2;

    modifying the second signal so that jammer signal component J2 is substantially anti-phase with respect to jammer signal component J1; and

    using the modified second signal to modify the first signal to create a third signal containing desired signal components S1 and S2 and in which jammer signal component J2 substantially cancels jammer signal component J1,wherein modifying the second signal comprises deterministically calculating a phase shift based on the amplitudes of the first, second, and third signals and applying the calculated phase shift to the second signal.
