ABSTRACT:
A navigation satellite receiver for demodulating spread spectrum transmissions on pairs of L-band microwave carrier frequency channels, L1 and L2, which use the same pseudorandom number spreading code. A single P(Y)-code generator is used to produce independent P(Y)-code outputs for L1 and L2. The relative P(Y)-code phase between the outputs is adjusted by a phase resolver to account for the dissimilar delays the ionosphere imposes on each of L1 and L2. The phase resolver counts the excess of L1 code clocks over the L2 code clocks with a digital counter and adjusts a digital delay line to compensate.
