Abstract:
1. A method for satellite-based navigation using a satellite-based navigation device having a processor, comprising: receiving, at the device, input from a user corresponding to an intended destination; calculating, using the device, a set of navigation instructions constituting a defined route from a starting point to the intended destination; determining, using the device, after the calculating, that the user has entered a neutral zone geographic region at an intermediate position along the defined route, wherein the neutral zone geographic region includes a portion of the defined route and one or more vehicle stopping locations proximate to the portion of the defined route and does not include beginning and end points of the defined route, wherein the one or more vehicle stopping locations corresponds to at least one of the group consisting of: a rest stop, a gas station, a restaurant, and lodging; and suppressing, at the device, route recalculation while the vehicle remains in the neutral zone geographic region; wherein neutral zone geographic regions are defined based on defined routes such that it is possible for a part of a roadway that is included within a neutral zone geographic region of a first defined route to not be included within any neutral zone geographic region of a second defined route.
