Abstract: A signal acquisition and tracking device includes an input configured to receive a global navigation satellite system (GNSS) signal, a software-based processor configured to execute software instructions to acquire the GNSS signal via the input and to generate, based on the acquired signal, one or more signal tracking parameters, and a hardware logic circuit operatively coupled to the processor. The logic circuit is configured to track the GNSS signal independently of the processor using the one or more signal tracking parameters generated by the processor. In some examples, the processor is configured to pull in and center the GNSS signal in time and frequency, and the logic circuit is further configured to track the pulled in and centered GNSS signal independently of the processor. In some examples, the processor acquires the signal and then hands-off control to the logic circuit for subsequent tracking of the signal.
