Abstract

A method of operation of a navigation system includes: detecting a light intensity; and selecting a route determined by the light intensity for displaying on a device.

Claims

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

detecting with a control unit a light intensity as a measurement of electromagnetic radiation;

selecting a route determined by the light intensity for displaying on a device; and

calculating an estimated remaining power level with the light intensity.

2. The method as claimed in claim 1 further comprising sending a data request for the light intensity.

3. The method as claimed in claim 1 further comprising estimating a potential travel distance with the light intensity.

4. The method as claimed in claim 1 further comprising presenting a notification based on the light intensity.

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

receiving a current power level;

detecting with a control unit a light intensity as a measurement of electromagnetic radiation based on the current power level;

selecting a route determined by the light intensity for displaying on a device; and

calculating an estimated remaining power level with the light intensity.

6. The method as claimed in claim 5 further comprising comparing a predetermined minimum power level to the current power level.

7. The method as claimed in claim 5 further comprising identifying a power replenishment location along the route.

8. The method as claimed in claim 5 further comprising recalculating the route based on a low light intensity indicator.

9. The method as claimed in claim 5 further comprising recalculating the route based on a time change indicator.

10. A navigation system comprising:

a control unit for detecting a light intensity as a measurement of electromagnetic radiation;

a location unit, coupled to the control unit, for selecting a route determined by the light intensity for displaying on a device; and

a prediction module, coupled to the location unit, for calculating an estimated remaining power level with the light intensity.

11. The system as claimed in claim 10 further comprising a user interface, coupled to the location unit, for sending a data request for the light intensity.

12. The system as claimed in claim 10 wherein the control unit is for estimating a potential travel distance with the light intensity.

13. The system as claimed in claim 10 further comprising a user interface, coupled to the location unit, for presenting a notification based on the light intensity.

14. The system as claimed in claim 10 further comprising a user interface, coupled to the location unit, for receiving a current power level, the light intensity based on the current power level.

15. The system as claimed in claim 14 wherein the control unit is for comparing a predetermined minimum power level to the current power level.

16. The system as claimed in claim 14 wherein the control unit is for identifying a power replenishment location along the route.

17. The system as claimed in claim 14 wherein the control unit is for re-calculating the route based on a low light intensity indicator.

18. The system as claimed in claim 14 wherein the control unit is for re-calculating the route based on a time change indicator.
