Systems and methods are provided for complementary navigation devices with
various integrated positioning functionality. The navigation method
includes providing a first navigation device. The first navigation device
includes a triangulation positioning functionality. The method includes
providing a second navigation device adapted to communicate with the first
navigation device. The second navigation device includes one or more dead
reckoning positioning components. The method further includes resolving a
position of the first and the second navigation devices. Resolving the
position includes using the one or more dead reckoning positioning
components in complement to the triangulation positioning functionality to
determine the position when the triangulation positioning functionality is
degraded.
