Navigation device for dead reckoning
First Claim
1. A navigation device, comprising:
- a receiver configured to receive a satellite signal;
a display;
a processor operatively coupled to the receiver and display, the processor being configured to;
track a path of the navigation device based on a first signal received by the receiver; and
calculate a calculated position of the navigation device based on a second signal provided by a vehicle and different from the first signal; and
display on the display a graphical user interface including a calculated position graphical element representing the calculated position determined based on the second signal and a tracked position graphical element representing the path of the navigation device determined based on the first signal, the tracked position graphical element and the calculated position graphical element being distinguishable in appearance.

Abstract
A navigation device is provided that includes a processor configured to track a path of the navigation device based on a first signal received by the navigation device, and calculate a calculated position of the navigation device based on a second signal different from the first signal. The navigation device may further include a graphical user interface configured to display a calculated position graphical element representing the calculated position determined based on the second signal and display a tracked position graphical element representing the path of the navigation device determined based on the first signal, the tracked position graphical element and the calculated position graphical element being distinguishable in appearance.

12. A method for dead reckoning for use with a navigation device having a receiver, a port, and a display, the method comprising:
-
tracking a path of the navigation device based on a first signal received by a first one of the receiver or the port in the navigation device; and calculating a calculated position of the navigation device based on a second signal different from the first signal, the second signal received by a second one of the receiver or the port; and displaying a graphical user interface on the display, the graphical user interface including a calculated position graphical element representing the calculated position determined based on the second signal and displaying a tracked position graphical element representing the path of the navigation device determined based on the first signal, the tracked position graphical element and the calculated position graphical element being distinguishable in appearance. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A computer readable storage medium comprising stored instructions that when executed by a processor of a navigation device cause the navigation device to:
-
track a path of the navigation device based on a first signal received by a port or a receiver in the navigation device; and calculate a calculated position of the navigation device based on a second signal different from the first signal; and display on a graphical user interface of a display a calculated position graphical element representing the calculated position determined based on the second signal and display a tracked position graphical element representing the path of the navigation device determined based on the first signal, the tracked position graphical element and the calculated position graphical element being distinguishable in appearance.
