Abstract: The present invention discloses a control stick for controlling an UAV formed by a bar with buttons on the bar head and a GUI displaying airplane like icons providing feedback of current steering control status of a UAV.

Abstract: Local wind fields can be predicted if both the airspeed and the ground speed of the helicopter are known. An aircraft that uses an inertial navigation unit, autopilot and estimator allows a measure of ground speed to be known with good certainty. The embodiments herein extends this system to allow an estimate of the local wind field to be found without actively using an airspeed sensor, but instead combining the measurements of an accelerometer and a drag force model and a model of controlled aerodynamics of the aircraft to estimate the airspeed, which again can be used to estimate the local wind speed.

Abstract: The embodiments herein disclose a method and a remote control for controlling and monitoring surrounding areas of an Unmanned Aerial Vehicle (UAV) by an operator with a remote control comprising a flight display. The embodiments disclose a surprising advantageously effect for the purposes of controlling and monitoring the surroundings of a UAV by combining the image captured by a UAV camera with a transparently overlaid positional and navigation map providing a perception enabling the operator to have a complete overall view of the situation, utilizing a common screen section of a flight display and thereby not having to shift eye view. Viewing images and positional and navigation information in the way described has shown not to interfere with each other, rather on the contrary.

Abstract: A method and device for precise control of and controller design for aircrafts consisting of at least one spinning part and at least one non spinning part is provided. The required torques for control of the spinning parts and for the non-spinning parts are continuously and individually calculated. All torques are combined to get the correct torque for the complete aircraft. Doing this, it's possible to continuously apply the correct torque, both correctly distributed among the roll and pitch axes (correct angle), and correct magnitude. The result is a decoupling of the roll and pitch axes, simplifying controller design to a design of two single input single output controllers, one for each axe.
