Abstract
There is disclosed a multi channel GPS digital signal processor on a single IC. Each channel contains circuitry to process L1 or L2 P(Y) and C/A-code signals. In addition a search processor is included to achieve fast signal acquisition. Low power adder/accumulators have been designed to provide for a high precision digital oscillator whose output is synchronous to a high speed clock. The IC contains a full low power null detector and eight correlators to aid in signal acquisition.
