    compensating for a bias in a local clock of said mobile receiver with respect to a frame timing of a repeating code broadcast by said satellite in response to said timing reference;

    obtaining an expected code delay window for said satellite positioning system signal at said mobile receiver; and

    correlating said satellite positioning system signal with a reference code within said expected code delay window.
