1. A method comprising:
- determining, at a navigation device, a plurality of routes between a source location and a destination location;
determining a reliability rating for each of the plurality of routes based, at least in part, on a count of navigation satellites that are available along a corresponding;
route,wherein the count of navigation satellites that are available along a first route of the plurality of routes is based, at least in part, on a count of navigation satellites that are available at each of a plurality of sample points along the first route;
determining that the count of navigation satellites that are available at a first sample point of the plurality of sample points along the first route is below a threshold;
determining whether connectivity to an access point of a wireless communication network is available in response to determining that the count of navigation satellites that are available at the first sample point is below the threshold,wherein the reliability rating of the first route is further based, at least in part, on whether connectivity to the access point is available;
identifying the first route of the plurality of routes as a preferred route based, at least in part, on the reliability rating of the first route; and
presenting the first route at the navigation device.

Abstract
A routing system can be configured to determine a route based on availability and reliability of location reference devices to determine a most reliable route between a source and a destination. A reliability rating associated with each route of a plurality of routes can be determined based, at least in part, on a count of navigation satellites available along the route. The reliability rating can be indicative of an ability of the routing system to maintain continuous connectivity to the navigation satellites along each of the plurality of routes. The reliability ratings of the plurality of routes are compared to identify and to present one of the plurality of routes as a referred route.

9. A navigation device comprising:
-
a processor; a routing unit coupled with the processor, the routing unit configured to determine a plurality of routes between a source location and a destination location; a route reliability calculation unit coupled with the processor, the route reliability calculation unit configured to, determine a reliability rating for each of the plurality of routes based, at least in part, on a count of navigation satellites that are available along a corresponding route wherein the count of navigation satellites that are available along a first route of the plurality of routes is based, at least in part, on a count of navigation satellites that are available at each of a plurality of sample points along the first route; determine that the count of navigation satellites that are available at a first sample point of the plurality of sample points along the first route is below a threshold; and determine whether connectivity to an access point of a wireless communication network is available in response to determining that the count of navigation satellites that are available at the first sample point is below the threshold, wherein the reliability rating of the first route is further based, at least in part, on whether connectivity to the access point is available; the routing unit further configured to, identify the first route of the plurality of routes as a preferred route based, at least in part, on the reliability rating of the first route; and present the first route at the navigation device. - View Dependent Claims (10, 11, 12)

13. A non-transitory machine-readable storage medium having machine executable instructions stored therein, the machine executable instructions comprising instructions to:
-
determine a plurality of routes between a source location and a destination location; determine a reliability rating for each of the plurality of routes based, at least in part, on a count of navigation satellites that are available along a corresponding;
route wherein the count of navigation satellites that are available along a first route of the plurality of routes is based, at least in part, on a count of navigation satellites that are available at each of a plurality of sample points along the first route;determining that the count of navigation satellites that are available at a first sample point of the plurality of sample points along the first route is below a threshold; determining whether connectivity to an access point of a wireless communication network is available in response to determining that the count of navigation satellites that are available at the first sample point is below the threshold, wherein the reliability rating of the first route is further based, at least in part, on whether connectivity to the access point is available; identify the first route of the plurality of routes as a preferred route based, at least in part, on the reliability rating of the first route; and present the first route at a navigation device. - View Dependent Claims (14)
