Abstract
Systems and methods for improved location accuracy are provided. For example, some systems can include a location engine, and a plurality of location anchors. In some embodiments, each of the plurality of location anchors can transmit or receive signals to or from an object for determining an angular orientation of the object with respect to the plurality of location anchors, and based on the angular orientation, the location engine can estimate a location of the object. In some embodiments, each of the plurality of location anchors can transmit first signals to the location engine, the location engine can receive a second signal from an object, based on the first signals and the second signal, the location engine can determine a differential pressure between the plurality of location anchors and the object, and based on the differential pressure, the location engine can estimate an altitude of the object.
