  • Low power minimal rate global navigation satellite system signal tracking system
    Patent number: 10830903
    Abstract: A global navigation satellite system (GNSS) signal tracking system (GNSSSTS), deployed in a tracking channel of a GNSS baseband engine, includes a piecewise down sampling module for generating code bit accumulated values (CBAVs) at different time instants at a reduced rate from samples of intermediate frequency data received at a high rate, and a pseudo random noise (PRN) code generation module for generating a PRN code bit sequence (PRNCBS) corresponding to a GNSS signal and storing arms of the PRNCBS. The GNSSSTS includes a primary mixer for generating a despread value for a selected arm of the PRNCBS and a phase component generation module (PCGM) for generating inphase and quadrature phase correlation components of the despread value for storage in a storage array. The primary mixer, the PCGM, and the storage array perform their functions continuously for each CBAV generated at a corresponding time instant in a time multiplexed manner.
