Abstract: A method and system are provided. The method includes receiving, by a GNSS receiver, a GNSS signal, rotating, by a carrier rotator, samples of the GNSS signal with carrier phase inputs, inverting, by a chip matched filter (CMF), the rotated samples, and generating, by the CMF, an output based on the inverted samples.

Abstract: A system and a method are disclosed for calculating correlations with different context lengths. In some embodiments, the system includes: a correlation engine; and a first input sample memory operatively coupled to the correlation engine, the correlation engine including a channel selection controller and being configured, under the control of the channel selection controller: to execute, during a first execution interval, a first channel, the first channel having a first context length; and to execute, during the first execution interval, a second channel, the second channel having a second context length, different from the first context length.

Abstract: A method and an apparatus are provided in which data is loaded from a memory to an input sample memory (ISM) of a user equipment (UE). The data corresponds to input from an L5 antenna of the UE. A first high-resolution correlation (HRC) engine of the UE performs coherent correlation and accumulation on the data for at least one code-frequency offset combination, to generate coherent correlation results. A second HRC engine of the UE processes the coherent correlation results by at least performing frequency widening and non-coherent accumulation to generate non-coherent correlation results indicating at least peak accumulations of correlations.
