Fast GNSS signal acquisition for a maneuverable vehicle in low-SNR environment

An electronic device comprising:

• a device architecture comprising a tracking engine (TE), wherein the TE comprises a plurality of TE channels, each TE channel comprising a plurality of correlators,
• wherein in a first mode of the electronic device, the electronic device is configured to:
• divide the plurality of TE channels into a first group of TE channels and a second group of TE channels;
• configure the first group of TE channels to search for and detect a plurality of signals in parallel, search for and detect the plurality of signals according to a sequential order, or both;
• determine a set of uncertainties associated with searching for and acquiring the plurality of signals, wherein the set of uncertainties comprises:
• position uncertainty associated with the electronic device;
• velocity uncertainty associated with the electronic device;
• and
• acceleration uncertainty associated with the electronic device;
• and
• maintain or update at least one uncertainty of the set of uncertainties based on processing the set of uncertainties using one or more equations;
• and
• configure the second group of TE channels to validate and track the detected plurality of signals,
• wherein in a second mode of the electronic device, the electronic device is configured to configure the first group of TE channels and the second group of TE channels to track the detected plurality of signals,
• wherein the electronic device is configured to receive direct sequence (DS) spread spectrum (SS) signals.
