Multi-part navigation process by an unmanned aerial vehicle for navigating to a medical situatiion

A method comprising:

• determining, by a computing system of a unmanned aerial vehicle (UAV), an approximate target location associated with a medical situation;
• using, by the computing system, a first navigation process to navigate the UAV from a remote location to the approximate target location of the medical situation, wherein the first navigation process generates first flight-control signals based on the approximate target location of a medical situation;
• making, by the computing system, a determination that the UAV is located at the approximate target location of the medical situation;
• and
• in response to the determination that the UAV is located at the approximate target location of the medical situation, using, by the computing system, a second navigation process to navigate the UAV to the medical situation, wherein the second navigation process generates second flight-control signals based on real-time localization of the medical situation.

A non-transitory computer readable medium having stored therein instructions that are executable to cause a computing device to perform functions comprising:

• determining an approximate target location associated with a medical situation;
• using a first navigation process to navigate an unmanned aerial vehicle (UAV) from a remote location to the approximate target location of the medical situation, wherein the first navigation process generates first flight-control signals based on the approximate target location of a medical situation;
• making a determination that the UAV is located at the approximate target location of the medical situation;
• and
• in response to the determination that the UAV is located at the approximate target location of the medical situation, using a second navigation process to navigate the UAV to the medical situation, wherein the second navigation process generates second flight-control signals based on real-time localization of the medical situation.

A method comprising:

• determining, by a computing system of an unmanned aerial vehicle (UAV), an approximate target location associated with a medical situation;
• using, by the computing system, a first navigation process to navigate the UAV from a remote location to the approximate target location of the medical situation, wherein the first navigation process generates first flight-control signals based on the approximate target location of a medical situation;
• either:
• (a) making a determination, by the computing system, that the UAV is located at the approximate target location of the medical situation or (b) receiving, by the computing system, local target-location data that is usable to navigate to the medical situation;
• in response to either (a) or (b), using, by the computing system, a second navigation process to navigate the UAV to the medical situation, wherein the second navigation process generates second flight-control signals based on real-time localization of the medical situation.
