Multi-part Navigation Process by an Unmanned Aerial Vehicle for Navigation
First Claim
1. An unmanned aerial vehicle (UAV) comprising:
- a navigation module that provides both a first and a second navigation process to generate flight-control signals for a UAV, wherein the first navigation process generates first flight-control signals based on a predetermined location of a target, and wherein the second navigation process generates second flight-control signals based on a real-time localization process that locates the target in real-time; and
a control system configured to;
determine an approximate target location associated with the target;
use the first navigation process to navigate the UAV from a first location to the approximate target location of the target;
make a determination that the UAV is located at the approximate target location of the target;
in response to the determination that the UAV is located at the approximate target location of the target, switch to use of the second navigation process to locate, and navigate the UAV to, a position hovering above the target; and
determine that the UAV is positioned above the target and responsively operate a winch system to lower a payload from the UAV to the target.

Abstract
Embodiments described herein may relate to an unmanned aerial vehicle (UAV) navigating to a target in order to provide medical support. An illustrative method involves a UAV (a) determining an approximate target location associated with a target, (b) using a first navigation process to navigate the UAV to the approximate target location, where the first navigation process generates flight-control signals based on the approximate target location, (c) making a determination that the UAV is located at the approximate target location, and (d) in response to the determination that the UAV is located at the approximate target location, using a second navigation process to navigate the UAV to the target, wherein the second navigation process generates flight-control signals based on real-time localization of the target.
