Abstract: In some implementations, a processor may retrieve predicted positioning data and predicted orbital data from global navigation satellite service (GNSS) positioning circuitry of a wireless device in response to a request for device time. The processor may retrieve long-term learning (LTL) data for a temperature sensing crystal (TSX) of the wireless device, the LTL data including S-curve characteristics of the TSX, and the time tracking uncertainty of the TSX. The processor may generate a GNSS-based device time estimate using the predicted positioning data and the predicted orbital data. The processor may perform TSX-based device time processing by updating the GNSS-based device time estimate using a clock signal of the TSX to generate a final device time estimate, the updating based on the retrieved LTL data for the TSX.

Abstract: A system for vehicle navigation may include a recognition circuit and a navigation circuit. The recognition circuit may determine a vehicle type based on received vehicle data. The navigation circuit may retrieve a navigation route between a starting location and a destination location, and modify the navigation route based on the determined vehicle type. The navigation circuit may also display a portion of the modified navigation route associated with a current location of the vehicle. The displayed portion of the navigation route may provide speed limit information based on the determined vehicle type. The recognition circuit may determine dimensions of the vehicle based on the vehicle data. The navigation circuit may determine parking information along the navigation route, based on the vehicle dimensions.
