This article explores the phenomenon of location spoofing—where the spoofer is able to “teleport” systems in and out of defined locations, either for the purpose of infiltration into no-go zones or for the “teleportation” out of real, defined zones in the physical world. The research relied on a qualitative methodology, utilising academic research findings, media reports, hacker demonstrations, and secondary data from these sources, to situate the spoofing threat in the context of international security. This conceptual, argumentative essay finds that signal spoofing, the methods of which can be followed via online scripts, allows users the ability to overcome geographically defined territorial restrictions. This, as this article finds, allows violent actors to weaponise systems, such as unmanned aerial systems, potentially leading to the escalation of political tensions in extreme but unfortunately ever-frequent episodes. The article concludes that, while Trojan spoofing (in particular) poses a real and an existential threat to international security, it is only a sum-of-all parts in considering other threats to critical functions in society. If geofences are used as a single point of security to protect assets against hostile actors, managers need to be aware of the vulnerability of intrusion and the resulting geopolitical consequences.

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.

W ramach pracy wykonano bezzałogowy system latający w konfiguracji z czterema silnikami zwany quadrocopterem. Głównym sterownikiem jest Raspberry Pi2 wraz z trzema dołączonymi modułami odpowiedzialnymi za sterowanie prędkością obrotową silników, wykonywanie pomiarów prędkości kątowej i przyspieszenia oraz zapewnienie łączności zgodnie ze standardem Wi-Fi.

This article introduces the synthetic material for future Unmanned Aerial Systems (UAS). The issues raised in it mainly concern the autonomy of these systems, applied design, propulsion systems, equipment and development trends in the UAS market. In addition, it presents global trends regarding methods of use, application and use of Unmanned Aerial Systems. Observing the growing realm of UAV in military actions it is expected to be the development of autonomous platforms implementing transport and combat missions. Increasingly used UAV platforms in military action jointly with manned platforms (mix formation) and in mixed formations of unmanned (UAV swarms differently equipped). Usage of unmanned aircraft in the civil sphere is very extensive and includes rescue operations – coordination and support, research – geodetic and cartographic, environmental protection, agriculture – monitoring of farmlands, natural resources, system warning of natural disasters; monitoring traffic – map navigation system; taking pictures and videos; data transfer.
