Opis:
An unmanned aerial vehicle is a flying apparatus that does not require a crewmember on board to complete a task. Its piloting is done by means of indirect control. UAVs also have the ability to perform autonomous flight on a pre-programmed flight path. The purpose of the study was to use the unmanned aircraft "Fly Eye" by WB Electronic used by the Border Guard to patrol the state border in 103 TRA zone on the section of the Republic of Poland with the Kaliningrad District of the Russian Federation. The TRA zones constitute a specially designated area for the use of the Border Guard and the army, in order to carry out flights there beyond the scope of the pattern for training purposes and to patrol the state border. The article also contains information of the Border Guard formation and the characteristics of the unmanned aerial vehicle “FlyEye”. In order to ensure the safety of the UAV flight, the test was carried out in the TRA zone, which is used for special use for the Border Guard formation and the army.

Opis:
The following study is devoted to the phenomenon of unmanned aerial vehicles used throughout known history on the battlefield or for military purposes. The purpose of the following text is to familiarise the reader with an overview with the contemporary and historical employment of the unmanned vehicles on the battlefield. The study also aims to show that the concept of unmanned combat vehicles, also unmanned aerial combat vehicles, is far more ancient than is it is widely known. The article is based on theoretical research methods, mostly multinational academic literature. The author starts with an introduction on the role of limiting soldiers’ fatalities and the concept of removing military men from the battleground. Then, the author presents known examples of using unmanned ships in battles from Thucydides’ times to the invention of the Hell-burner of Antwerp. Further, the case of first unmanned combat aerial vehicle is presented, the bombing balloons from the nineteenth century, followed by a more contemporary study of the military use of unmanned aircrafts. The article is concluded with an analysis of the present employment of drones when they tend to substitute manned aircrafts on various occasions, especially when a mission is deemed “dull, dirty or dangerous”.

Opis:
A design of an unmanned aerial vehicle (UAV) construction, intended for autonomous flights in a group, was presented in this article. The design assumptions, practical implementation and results of the experiments were given. Some of the frame parts were made using 3D printing technology. It not only reduces the costs but also allows for better fitting of the covers to the electronics, which additional-ly protects them against shocks and dirt. The most difficult task was to develop the proper navigation system. Owing to high costs of preci-sion positioning systems, common global positioning system (GPS) receivers were used. Their disadvantage is the floating position error. The original software was also described. It controls the device, allows performing autonomous flight along a pre-determined route, anal-yses all parameters of the drone and sends them in a real time to the operator. The tests of the system were carried out and presented in the article, as well.

Opis:
Geospatial data obtained using Unmanned Aerial Vehicles (UAVs) and Unmanned Surface Vehicles (USVs) are increasingly used to model the terrain in the coastal zone, in particular in shallow waterbodies (with a depth of up to 1 m). In order to generate a terrain relief, it is important to choose a method for modelling that will allow it to be accurately projected. Therefore, the aim of this article is to present a method for accuracy assessment of topo-bathymetric surface models based on geospatial data recorded by UAV and USV vehicles. Bathymetric and photogrammetric measurements were carried out on the waterbody adjacent to the public beach in Gdynia (Poland) in 2022 using a DJI Phantom 4 RTK UAV and an AutoDron USV. The geospatial data integration process was performed in the Surfer software. As a result, Digital Terrain Models (DTMs) in the coastal zone were developed using the following terrain modelling methods: Inverse Distance to a Power (IDP), Inverse Distance Weighted (IDW), kriging, the Modified Shepard’s Method (MSM) and Natural Neighbour Interpolation (NNI). The conducted study does not clearly indicate any of the methods, as the selection of the method is also affected by the visualization of the generated model. However, having compared the accuracy measures of the charts and models obtained, it was concluded that for this type of data, the kriging (linear model) method was the best. Very good results were also obtained for the NNI method. The lowest value of the Root Mean Square Error (RMSE) (0.030 m) and the lowest value of the Mean Absolute Error (MAE) (0.011 m) were noted for the GRID model interpolated with the kriging (linear model) method. Moreover, the NNI and kriging (linear model) methods obtained the highest coefficient of determination value (0.999). The NNI method has the lowest value of the R68 measure (0.009 m), while the lowest value of the R95 measure (0.033 m) was noted for the kriging (linear model) method.

Opis:
The design process is mostly connected with a proper selection of construction materials. Newly designed UAVs must undergo assessment in terms of performed tasks, range or fuel consumption. A significant influence upon the selection of materials, which are long lasting and resistant to damage, is exerted by the conditions of work of Unmanned Aerial Vehicles. They mainly execute their tasks at high altitudes with high speeds, where temperature and pressure differences may extensively damage not only the airframe skin, but also the equipment and the propulsion system itself. The aim of this study is to present the characteristics of materials currently used as well as their assessment in employed construction elements of UAVs. Polymer composites are superior to Al and Ti alloys, steel within the parameters of tensile strength and stiffness. As for the density gradient, polymer carbon fibre composites exceed glass fibre composites, also under cyclically variable loads. Glass fibre composites during tensile testing show higher values and a higher capability of absorbing energy under static and dynamic forces. Polymer matrix composites, reinforced with Kevlar, are less stiff than carbon-fibre composites, due to lower values of elasticity modulus, however they demonstrate higher impact load. Strength tests provide valuable data concerning the properties of a given material, such as tensile modulus E [MPa], tensile strength UTS [MPa], or resistance to high temperatures. It must be noted that these properties significantly affect the functioning of the airframe and its components.

Opis:
Unmanned aerial vehicles are used to observe objects from the air in both kind of users – military and civilian. During the flight, UAV constantly is changing its orientation. This is due to weather conditions and commands coming from the ground control station. It has directly influence to the quality of the video stream transmitted from the cameras to the GCS. That disturbed image is hard to effective analyse. In order to eliminate the interference, UAVs are equipped with stabilized gimbals. The most of gimbals designed in Air Force Institute of Technology are using BLDC motors. Some of these systems use encoders for determining the absolute angle of motor rotation. The smaller one, which is up to 200 g, is not provided with these sensors. This angle is calculated without any feedback from the system. It is calculated by the BLDC motor`s control signals. However, lack of feedback can provide unstable work of gimbal, if it will be pushed by any force from environment. During the flight, it is unacceptable to head optoelectronic stopped working steadily. Therefore, there is a need to develop algorithms for securing the proper operation of the system stability. These algorithms can be used in other systems using stepper or BLDC motors.
