Systems and methods for generating vertical positioning information for unmanned aerial vehicles

A method, comprising:

• measuring, by an unmanned aerial vehicle (UAV), barometric pressure;
• generating, by the UAV, a request for elevation data and barometric pressure data;
• transmitting the request to at least one other device;
• receiving, from each of the at least one other device, elevation data and barometric pressure data;
• and
• estimating, by the UAV, the elevation of the UAV based on the measured barometric pressure, the received elevation data and the received barometric pressure data.

A non-transitory computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor included in a unmanned aerial vehicle (UAV), cause the at least one processor to:

• determine the barometric pressure;
• generate a request for elevation data and barometric pressure data;
• transmit, via the communication interface, the request to at least one other device;
• receive, from each of the at least one other device, elevation data and barometric pressure data;
• and
• estimate the elevation of the UAV based on the determined barometric pressure, the received elevation data and the received barometric pressure data.
