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. |
