System and method for thermal control during delivery of a medication package

A method for controlling an unmanned aerial vehicle for delivery of a perishable, the method comprising:

• identifying a thermal budget of the perishable;
• identifying a destination for the perishable;
• identifying a plurality of environmental characteristics along a three-dimensional flight path between pick-up location and the destination;
• determining, at a processor, whether the perishable can be delivered at the destination without expending the thermal budget of the perishable;
• measuring, by a plurality of sensors, an amount of sun exposure at the destination;
• in response to delivery of the perishable, generating a first adjusted thermal control period based on:
• the thermal budget;
• the plurality of environmental characteristics;
• and
• the measured amount of sun exposure;
• instructing, by the processor, the unmanned aerial vehicle to selectively retrieve and return the perishable to the pick-up location by a first time the first adjusted thermal control period expends;
• and
• canceling, selectively, the instructing of the unmanned aerial vehicle to retrieve and return the perishable based on a recipient of the perishable receiving a communication from a recipient device that a recipient of the perishable claims the perishable.
