SYSTEM AND METHOD FOR ENHANCED INTEGRATED NAVIGATION WITH WIRELESS ANGLE OF ARRIVAL

摘要

The present disclosure relates to a system and method for integrated navigation integrating wireless measurements including at least angle of arrival (AOA) measurements with a navigation solution. This integrated navigation system provides an enhanced integrated navigation solution of a device within a platform (such as for example person, vehicle, or vessel), wherein the device can be strapped or non-strapped within the platform, wherein the device is non-strapped the mobility of the device may be constrained or unconstrained within the platform, and wherein the device can be tilted to any orientation and still provide a seamless navigation solution without degradation in performance of said navigation solution. The device may include sensors such as for example, accelerometers, gyroscopes, magnetometers, barometer among others. The present system and method can work whether in the presence or in the absence of absolute navigational information such as, for example, Global Navigation Satellite System (GNSS).

主权项

1. A method for integrating measurements from a wireless system comprising at least angle of arrival measurement(s) with a navigation solution about at least one wireless-enabled device, wherein the wireless system comprises at least one transceiver means at any location within a wireless network area, wherein the at least one transceiver is capable of transmitting a wireless signal, wherein the measurements of the wireless system are generated from said signal(s), wherein the at least one device is capable of receiving the signal(s) from the at least one transceiver means, the method comprising:
a. receiving the signal(s) transmitted from the at least one transceiver means, and generating the wireless measurements, b. obtaining information from the transmitted signal(s) that identifies the at least one transceiver means, c. integrating the wireless measurements with the navigation solution.
