System and method for improved location accuracy

摘要

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.

1. A location anchor comprising:
a transceiver; a programmable processor; executable control software stored on a non-transitory computer readable medium; a plurality of directional transmitters or a plurality of directional receivers of electromagnetic radiation; and a pressure sensor, wherein the plurality of directional transmitters or the plurality of directional receivers are positioned about a perimeter of the location anchor, wherein the directional transmitters are configured to transmit first signals to an object at a plurality of identifiable angles or the plurality of directional receivers are configured to receive second signals from the object at a plurality of identifiable angles, wherein, based on the first signals or based on the second signals, a location engine is configured to determine an angular orientation of the object with respect to the location anchor, wherein the transceiver is configured to transmit a signal that includes information related to a reading from the pressure sensor to a location engine, and wherein, based on the signal that includes the information related to the reading from the pressure sensor, the location engine is configured to: determine a differential pressure between the pressure sensor and a second pressure sensor in the object, and, based on the differential pressure, the location engine is further configured to estimate an altitude of the object.
