ALTITUDE ESTIMATION FOR AERIAL VEHICLES - SZ DJI TECHNOLOGY CO LTD

Title:

ALTITUDE ESTIMATION FOR AERIAL VEHICLES

Document Type and Number:

WIPO Patent Application WO/2019/037100

Kind Code:

A1

Abstract:

The altitude of a moving object, such as an unmanned aerial vehicle (UAV), is estimated as a function of pressure-dependent signals from a set of sensors (300-1, 300-2, 300-3, 300-4, 300-5) mounted on the object to enable them have different primary sensing orientations (N). The function may be a weighed average, and the weights in the function may be changed depending on such factors as vehicle orientation relative to apparent wind, stability of the sensed signals, and sensor failure.
