GPS modernization program offers a new civil signal on L2 band, which together with the legacy L1 C/A spurs the development of dual frequency receivers for civil applica- tions. This paper proposes a complete combined acquisi- tion architecture dedicated to these receivers. The archi- tecture fully utilizes the capacity of both the signal chan- nels as well as the advantages of differential signal process- ing. High detection sensitivity, finer parameter estimation, built-in bit synchronization mechanism, and acquisition- to-tracking transient time reduction are the advantages of the proposed architecture with respect to others in litera- ture
