Patent ID: 8417450

Claim:
A computing navigation device on board a vehicle, comprising: a processor configured to execute: a communication module configured to receive a global positioning satellite (GPS) system signal corresponding to a vehicle position of a vehicle and configured to recognize a dropped signal condition in which no operational signal is detected from the GPS system and GPS data is not being received, and configured to identify a last position of the vehicle corresponding to a time of the dropped signal condition, and configured to retrieve OBD data from an on-board diagnostics system of the vehicle corresponding with a movement of the vehicle; a kinematic module configured to calculate a calculated position of the vehicle based on the last position and the OBD data when the dropped signal condition is recognized by the communication module; and a graphical user interface configured to display a calculated position graphical element representing the calculated position during the dropped signal condition when GPS data is not being received and display a tracked position graphical element representing a path of the vehicle determined based on the GPS system signal during a signal receiving condition indicating an operational signal is being received from the GPS system, the tracked position graphical element and the calculated position graphical element being distinguishable in appearance.
