System and method for improved location accuracy
First Claim
1. A system comprising:
- a location anchor, wherein the location anchor comprises;
a transceiver;
a programmable processor;
executable control software stored on a non-transitory computer readable medium; and
a plurality of directional transmitters of electromagnetic radiation,wherein the plurality of directional transmitters 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, andwherein, based on the first signals, a location engine is configured to determine an angular orientation of the object with respect to the location anchor;
wherein each directional transmitter of the plurality of directional transmitters is configured to include information unique to a respective identifiable angle in a corresponding first signal of the first signals transmitted from the plurality of directional transmitters to the object.

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.
