摘要
A computing navigation device is disclosed that includes a processor configured to control a communication module configured to receive a global positioning satellite (GPS) system signal corresponding to a vehicle position of a vehicle. The processor may be further configured to recognize a dropped signal condition in which no operational signal is detected from the GPS system, and to identify a last position of the vehicle corresponding to a time of the dropped signal condition. The processor may be further configured to retrieve on-board diagnostics data from an on-board diagnostics system of the vehicle corresponding with a movement of the vehicle. The computing navigation device may further include a kinematic module configured to calculate a calculated position of the vehicle based on the last position and the movement of the vehicle, and a display configured to display a representation of the calculated position.
