1. A location determining device, comprising
a processor and memory configured to:
determine an indicated distance between a first detector of a vehicle and a source based on a signal originating at the source and detected by the first detector,
determine a second distance between the source and a second detector based on a signal originating at the source and detected by the second detector,
determine whether a portion of the vehicle obstructs a direct signal path between the source and the second detector based on a determined position of the second detector relative to the vehicle and a determined position of the vehicle relative to the source, and
determine a reliability of the indicated distance for determining a location of the vehicle by determining whether the indicated distance corresponds to a direct signal path between the first detector and the source based on a difference between the indicated distance and the second distance and based on whether the portion of the vehicle obstructs the direct signal path between the source and the second detector.
