Annotation on the master dissertation of the student Karlin

The article deals with the topical theme group use of unmanned aerial vehicles (UAV). This problem is promising and has many practical applications.

Typically, the practice used for single UAV leads to poor performance tasks, especially when the task is performed on unlimited big territory. Limitations associated with the fact that sensors and UAV sensors have a limited sphere of influence. Using multiple UAVs in the group increases the effectiveness of the task, but there are additional problems with coordination when performing other tasks. In this regard there is a task of group management use a limited number of the personnel of management of the UAV. All the above told is given in the literature.

The task of group use of the UAV is very actual as use of the UAV in group considerably increases efficiency of performance of a task thus a number of tasks is refuted. There is the possibility of monitoring large areas in a short time without loss of influential parts that are very likely using a single UAV. At group management interaction between separate UAVs is used so that there was a full compliance in their actions, with the task.

Solvable tasks UAV group with maximum efficiency: distribution of tasks between groups of separate UAVs by "vote", a choice of a favorable route, determination of coordinates of the purpose. Such and other options are investigated.

Among the unresolved problems at the moment we can note:

- Identification of a successful distribution strategy objects between UAV.

- Select the most successful route of UAVs for some issues remain unresolved.

Among the solved problems:

- Definition spherical coordinates - Definition advantageous route for 1UAV. The problem is solved.

Formulation of the problem

To set parameters required objects, UAV and meteorological conditions should be investigated:

- The most successful distribution strategy objects between UAV

- Pave the fastest route for each UAV include coordinates.

Rate criterion should be considered a minimum time of flight of the UAV (sometimes called flight of UAV time when the latest UAV reaches the destination, your route, provided that all the UAV began to move from the starting point of the route at the same time).

When calculating the route should take into account the possibility of influence of side winds through which UAVs may deviate from the course, which in turn changes the length of the trajectory and the success of the route.

Analyzing raw data, we can say that among the characteristics of UAVs to implement algorithms need the following:

• the range of variation of speed and altitude UAV;

• minimum radius turn dependent on the speed of flight and wind speed.

Given the fact that the aim of the thesis is to study the problem of determining the most advantageous flight path drones considering turning radius and distance to the object, both for individual UAVs or for group use. It is important to determine the most advantageous strategy for distribution objects between UAVs and pave the fastest route for each UAV. With the help of these unmanned vehicles may calculate the azimuthally angle, height and air anti-aircraft object.

Keywords: UAV, the algorithm group using UAVs, trilateration.
