Abstract

A method of operation of a navigation system includes: obtaining a first coverage location; determining a first coverage quality at the first coverage location is below a predefined threshold; generating an adaptive coverage area around the first coverage location for displaying on a device; selecting a preferred mode for positioning fix associated with the adaptive coverage area; and operating the preferred mode inside the adaptive coverage area.

obtaining a first coverage location;

determining a first coverage quality at the first coverage location is below a predefined threshold with a control unit;

generating an adaptive coverage area around the first coverage location for displaying on a device;

selecting a preferred mode for positioning fix associated with the adaptive coverage area; and

operating the preferred mode inside the adaptive coverage area.

2. The method as claimed in claim 1 further comprising:

identifying a current location outside the adaptive coverage area for locating a further device; and

projecting a boundary traversal into the adaptive coverage area.

3. The method as claimed in claim 1 further comprising:

obtaining a second coverage location outside the adaptive coverage area;

determining a second coverage quality at the second coverage location is below the predefined threshold; and

extending the adaptive coverage area to include the second coverage location.

4. The method as claimed in claim 1 further comprising:

obtaining a second coverage location inside the adaptive coverage area;

determining a second coverage quality at the second coverage location meets or exceeds the predefined threshold; and

decreasing the adaptive coverage area to exclude the second coverage location.

5. The method as claimed in claim 1 further comprising:

identifying a current location outside the adaptive coverage area for locating a further device;

obtaining a second coverage location outside the adaptive coverage area where the second coverage location includes the current location;

determining a second coverage quality at the second coverage location is below the predefined threshold; and

generating a further adaptive coverage area, not overlapping the adaptive coverage area, to include the second coverage location.

6. A method of operation of a navigation system comprising:

obtaining a first coverage location with a location unit;

location;

determining a first coverage quality at the first coverage location is below a predefined threshold with a control unit;

generating an adaptive coverage area around the first coverage location with the first coverage quality below the predefined threshold for displaying on a device;

selecting a preferred mode for positioning fix associated with the adaptive coverage area;

scheduling a switch to the preferred mode in anticipation of proceeding into the adaptive coverage area; and

operating the preferred mode inside the adaptive coverage area.

7. The method as claimed in claim 6 further comprising:

identifying a current location inside the adaptive coverage area for locating a further device; and

selecting a slow mode for positioning fix as the current location approaches a target location.
