Description
Method and system for steering an Unmanned Aerial Vehicle Technical Field The present invention relates to a method for steering a UAV, Unmanned Aerial Vehicle, to enable a high level command of the UAV, and to a system for steering the UAV to enable high level command of the UAV.
Background An UAV is an aircraft that is flown by an operator without a human crew on board the aircraft. Their largest uses are in military applications, but are expected to find many civilian applications in the future.
A UAV can fly autonomously or be piloted remotely. Some UAVs is equipped with autonomous guidance systems and automatic control systems which give the UAV the capacity to act as an independent flying vehicle.
UAVs can be equipped with different payloads for information collection and are able to perform tasks such as surveillance, reconnaissance, target acquisition, dissemination of target data and battle damage assessment.
Background An UAV is an aircraft that is flown by an operator without a human crew on board the aircraft. Their largest uses are in military applications, but are expected to find many civilian applications in the future.
A UAV can fly autonomously or be piloted remotely. Some UAVs is equipped with autonomous guidance systems and automatic control systems which give the UAV the capacity to act as an independent flying vehicle.
UAVs can be equipped with different payloads for information collection and are able to perform tasks such as surveillance, reconnaissance, target acquisition, dissemination of target data and battle damage assessment.
2 Usually two operators control one UAV. One operator handles the flying commands, and another operator handles the payloads on the UAV. There are also high level commands available which give the operators the ability to give more focus on the mission instead of flying. One example is a high level command that steers the UAV to a specific spatial position. Another example of a high level command is one in which the operator sets up a list of waypoints that the UAV
will fly to, starting with the first waypoint in the list and so on.
These types of high level commands however still require at least two operators. One operator handles the flying commands and another operator handles the payloads on the UAV.
There is therefore a need for an improved solution for high level command of the UAV that solves or at least mitigates at least one of the above mentioned problems.

There is therefore a need for an improved solution for high level command of the UAV that solves or at least mitigates at least one of the above mentioned problems.
3 Summary An object of the present invention is thus to provide a method and a system for enabling a high level command of the UAV
which only requires one operator.
According to a first aspect, the present invention relates to a method for steering a UAV, Unmanned Aerial Vehicle, to enable a high level command of the UAV. The method comprises the steps of: determining a reference position related to a position for a moving object which the UAV should follow; calculating a smoothed position based on the reference position, wherein the smoothed position is calculated so that the smoothed position moves more smoothly than the reference position and steering the UAV so that the UAV
follows the smoothed position.
Thus, the object is achieved according to the present invention by determining a reference position related to a position for a moving object which the UAV should follow and calculating a smoothed position based on the reference position. The smoothed position is calculated so that the smoothed position moves more smoothly than the reference position. Thus is a irregular behaviour of the object smoothed out by the present invention. The UAV is steered so that the UAV follows the smoothed position instead of the reference position. In this way the UAV follows the object and at the same time moves more smoothly than the object.

By the use of the present invention it would be possible to have the UAV flying at a distance ahead of the convoy and search for threats along and beside the road.
Other examples include target following, when keeping a fixed bearing and distance, and positioning of the UAV prior to landing on a moving platform.

Fig. 2 illustrates a way of determining the reference position 200 from the object position 210, where the UAV 235 will follow an arranged piecewise linear route of waypoints 222 and at the same time hold a specific distance to the object 220. The distance to the reference position 200 from the object 220 may be calculated by projecting the objects position 210 on the UAV route 222 and then add a reference distance 236 forward from the projected position 237.
Fig. 3 illustrates another way of determining the reference position 300 from the object position 310, where the UAV will keep a constant reference distance 316 and angle 315 to the object 320. The angle is set with respect to the north axis, but the angle 315 may also be set with respect to other axes.
Fig. 4 illustrates yet another way of determining the reference position 400 from the object position 410, where the UAV
holds a specific reference distance 416 and angle 405 to the object 420. It is similar to the way in fig. 3, the only difference is that the angle 405 is fixed to the moving direction of the object 420.

Figure 1 shows a system 100 for steering the UAV, to enable high level command of the UAV according to the present invention. The system 100 comprises a control unit 110 adapted to receive the reference position 200, 300, 400 related to a position 210, 310, 410 for the object 220, 320, 420 which the UAV should follow. The control unit 110 is further adapted
8 to calculate a smoothed position 230, 330, 430 based on the reference position 200, 300, 400. The smoothed position 230, 330, 430 is calculated so that the smoothed position 230, 330, 430 moves more smoothly than the reference position 200, 300, 400. In an exemplary embodiment of the system 100 according to the present invention, the control unit 110 is further adapted to regulate the smoothed position 230, 330, 430 to the reference position 200, 300, 400.

In a further exemplary embodiment of the system 100 according to the present invention the control unit 110 is adapted to allow the smoothed position 230, 330, 430 to have a margin of error from the reference position 200, 300, 400. The margin of error may be set by an operator of the system 100. The margin of error is a distance between the smoothed position 230, 330, 430 and the reference position 200, 300, 400.
In a yet further exemplary embodiment of the system 100 according to the present invention, the control unit 110 is further adapted to regulate the smoothed position with less gain when the smoothed position 230, 330, 430 lies within a margin of error from the reference position 200, 300, 400 and with more gain when the smoothed position 230, 330, 430 lies outside the margin of error from the reference position 200, 300, 400.

9 The reference position 200 may in an exemplary embodiment of the system 100 be determined based on a position 210 for the object 220 being projected on the route of waypoints 222 for the UAV and adding the reference distance 236 in a forward direction of the route of waypoints 222.
The smoothed position 230 will in this embodiment be moving along the UAV route of waypoints 222 and will be regulated towards the reference position 200. The smoothed position 230 has in an exemplary embodiment a regulation with less gain inside the margin of error and a regulation with more gain outside the margin of error to make the smoothed postion 230 stay inside the margin of error.
In another exemplary embodiment of the system 100 according to the present invention is the reference position 300 determined based on an angle 315 and a reference distance 316 to the object 320. In this exemplary embodiment is the UAV assumed to follow the object 320 and to keep a specific distance and angle 315 to the object 320. The angle 315 may be set to be constant between the latitude direction (north) and the direction from the UAV to the object 320.

Therefore the control unit 110 is adapted to control the smoothed position 330 in two directions, one for each dimension. The smoothed position 330 will be regulated to the reference position 300 and will have a margin of error to the reference position 300 were regulation is performed with less gain.

9. A system (100) according to any of claims 6-8, wherein said reference position (200, 300, 400) is determined based on an angle to a moving direction for said object and a distance to said object.
10. A system according to any of claims 6-9, wherein said reference position (200, 300, 400) is determined based on a position for said object being projected on a track for said UAV and adding a distance in a forward direction of said track.
