Abstract
Methods and systems are disclosed for evaluating the reliability of sensor measurements of environmental properties used for deriving the location of a mobile device. A mobile device can receive measurements of environmental properties made sensors of one or more other mobile devices concurrently with real-time measurements of the environmental properties made by sensors of the mobile device. The mobile device can determine that each of the other mobile devices is within a locality threshold of the mobile device. The mobile device can determine that a difference between at least one of the real-time measurements and a metric of the received measurements corresponds to a statistical likelihood that the at least one of the real-time measurements is unreliable. Any of the real-time measurements that are determined to be unreliable can be excluded from a location determination of the mobile device derived from the real-time measurements of the environmental properties.
