A navigation system is configured to identify a current location and a destination location of an airborne platform, identify a current cell in which the current location is located; identify a plurality of current neighbors associated with the current cell; calculate, for a first path from the current location to the destination location through a first current neighbor of the plurality of current neighbors, a first value of an objective function, the first value depending on whether the first path includes a predetermined navigational node; calculate, for a second path from the current location to the destination location through a second current neighbor of the plurality of current neighbors, a second value of the objective function depending on whether the second path includes a predetermined navigational node; and output the current neighbor and/or path that satisfies an objective condition based on the values.
