The change in the nature of armed conflicts forced a change in the way they were conducted and the need to develop new types of weapons. The article presents the basic assumptions regarding the use and development prospects of unmanned flying systems. Tactical and technical data of the leading structures are presented. At the same time, the directions of development and use of combat air systems in future armed conflicts were presented. It was pointed out that unmanned aerial systems, the use of which brings significant financial benefits, are the type of weapon that has recently been gaining in importance in the most spectacular way, transforming the face of armed conflicts. The use of unmanned aerial vehicles as part of training tasks and combat missions forces the continuous development of personnel in the field of skills related to hazard identification and assessment. This process requires professionals with a high level of substantive preparation and extensive aviation experience, who will increase the awareness of RPA operators in terms of the essence and the need to analyze and estimate risk. On the basis of analyzes and comparisons, the authors proposed that the development work and the construction of elements and the system (CUAS) to combat UAV become an opportunity for the development of national research institutes and the defense industry, and also Polish export product.

The conduct of warfare is constantly shaped by forces beyond the battlefield. These forces create complexities in the battlespace for military operations. The ever-changing nature of how and where wars are fought creates challenges for the application of the unchanging body of international law that regulates armed conflicts. The term “complex” is often used to describe modern warfare, but what makes modern warfare complex? Is it the increasingly urbanized battlefield where wars are fought, which is cluttered with civilians and civilian objects? Is it the rise of State-like organized armed groups that leverage the governance vacuum created by failed or failing States? Is it the introduction of new technologies to military operations like autonomous weapons, cyber capabilities, and unmanned aerial systems? Or is it the application of multiple legal regimes to a single conflict? Collectively, these questions formed the basis for the Complex Battlespaces Workshop in which legal scholars and experts from the field of practice came together to discuss these complexities. During the workshop, there was a general consensus that the existing law was sufficient to regulate modern warfare. The challenge, however, arises in application of the law to new technologies, military operations in urban environments, and other issues related to applying international human rights law and international humanitarian law to non-international armed conflicts. This inaugural volume of the Lieber Book Series seeks to address many of the complexities that arise during the application of international law to modern warfare.

The rapid increase of low-cost consumer-grade to enterprise-level unmanned aerial systems (UASs) has resulted in the exponential use of these systems in many applications. Structure from motion with multiview stereo (SfM-MVS) photogrammetry is now the baseline for the development of orthoimages and 3D surfaces (e.g., digital elevation models). The horizontal and vertical positional accuracies (x, y and z) of these products in general, rely heavily on the use of ground control points (GCPs). However, for many applications, the use of GCPs is not possible. Here we tested 14 UASs to assess the positional and within-model accuracy of SfM-MVS reconstructions of low-relief landscapes without GCPs ranging from consumer to enterprise-grade vertical takeoff and landing (VTOL) platforms. We found that high positional accuracy is not necessarily related to the platform cost or grade, rather the most important aspect is the use of post-processing kinetic (PPK) or real-time kinetic (RTK) solutions for geotagging the photographs. SfM-MVS products generated from UAS with onboard geotagging, regardless of grade, results in greater positional accuracies and lower within-model errors. We conclude that where repeatability and adherence to a high level of accuracy are needed, only RTK and PPK systems should be used without GCPs.

Since the beginning of the 21st century, there has been a noticeable increase in German efforts to ensure security in the Mediterranean Sea. This is part of the growing activities to ensure a strong strategic position in North and West Africa, including the settlement of existing armed conflicts here as sources of threats to instability for Germany and its EU partners. Consequently, Germany found itself increasingly interested in finding reliable strategic partners, one of which is Algeria, which makes the topic of this article relevant. The purpose of the study is to examine bilateral security and defense relations with a special focus on the second half of the 2010s and early 2020s with the help of comparative and event-analysis. Having an applied character, this topic has not yet found detailed coverage in the works of both domestic and foreign, especially German, researchers. The historic background of the German-Algerian dialogue is presented. The growth of high-level contacts in the second half of the 2010s is shown, with Germany having to focus on negotiations with the frequently changing figure of the Algerian prime minister. The article also explores the constraints for the cooperation of German and Algerian armed forces on land and sea, as well as the dynamics of military-technical cooperation. The bilateral cooperation in the resolution of the armed conflict in Mali, first of all, in its northern region (Gao, Kidal and Timbuktu) is considered. The political and diplomatic cooperation on the Libyan track in the middle and second half of the 2010s, as well as shortly after the Berlin Conference on Libya in January 2020, is revealed. In the early 2020s, there was a sharp decline in the intensity and volume of bilateral cooperation in almost all areas. In addition to COVID-19, the importance of domestic political factors and the temporary decline in the practical value of the partnership in Libya and Mali for Germany are stressed. A forecast of the dynamics of bilateral relations is finally given.

The Impact

Analysis of combat losses of aircraft in local armed conflicts in recent decades shows that most cases of aircraft hits are related to the impact of guided surface-to-air and air-to-air missiles equipped with homing warheads. The use of modern guided missiles equipped with homing warheads is one of the main threats to aircraft of various types. This is due to the fact that modern guided missiles are characterized by high speed, maneuverability, accuracy of aiming and difficulty of detection. Solving the problem of protecting aircraft from guided missiles consists of several stages: detection of missile launch; confirmation that the detected missile is heading directly toward the protected object; missile identification and decision-making on the most effective countermeasure system employment. At present, there are no missile launch detection systems that guarantee a 100% probability of threat detection, but an analysis of aviation combat losses in local armed conflicts in recent decades convincingly shows that the number of combat losses of aircraft equipped with such systems is much lower than those in which missile launch detection is carried out visually. For example, most of the Soviet Union's losses during the war in Afghanistan and the United States‟ losses during Operation “Desert Storm” in Iraq were related to the use of portable anti-aircraft missile systems, which missiles were equipped with infrared homing warheads. Realizing the scale of the threat posed by such missiles, most of the world's leading countries have significantly increased the expenses on development new or improvement existing countermeasures. As a result, the aggregate losses of coalition forces in Iraq, Afghanistan and Syria since 2001 clearly suggest that these costs have paid off, with losses from the use of portable anti-aircraft missile systems significantly reduced, while the total number of combat sorties increased. Therefore, in the face of all the challenges and threats posed to Ukraine due to the aggressive actions of the Russian Federation, conducting research in the interests of aviation of the Armed Forces of Ukraine to improve the effectiveness of missile detection systems for ensuring timely detection of threats, warning of aircraft crew and activation in the automatic mode the means of countermeasures is as relevant as ever.

Abstract The steadily increasing use of unmanned aerial systems (UAS) is an important factor for the military and civil aviation safety on a global scale. One of the critical conditions for the efficient functioning of the European aviation safety system is the establishment and implementation in practice of a comprehensive regulatory framework for the use of unmanned systems in the Common European Airspace. The aviation authorities and industry strive to introduce a set of rules and requirements that adequately and flexibly guarantee a high level of safety without limiting the development of the UAS market. This article proposes a set of standards that should be met by “Open” category UAS with the intention to execute operations in the European airspace.

Small unmanned aerial systems (UASs) now have advanced waypoint-based navigation capabilities, which enable them to collect surveillance, wildlife ecology and air quality data in new ways. The ability to remotely sense and find a set of targets and descend and hover close to each target for an action is desirable in many applications, including inspection, search and rescue and spot spraying in agriculture. This paper proposes a robust framework for vision-based ground target finding and action using the high-level decision-making approach of Observe, Orient, Decide and Act (OODA). The proposed framework was implemented as a modular software system using the robotic operating system (ROS). The framework can be effectively deployed in different applications where single or multiple target detection and action is needed. The accuracy and precision of camera-based target position estimation from a low-cost UAS is not adequate for the task due to errors and uncertainties in low-cost sensors, sensor drift and target detection errors. External disturbances such as wind also pose further challenges. The implemented framework was tested using two different test cases. Overall, the results show that the proposed framework is robust to localization and target detection errors and able to perform the task.

We present an automatic agave detection method for counting plants based on aerial data from a UAV (Unmanned Aerial Vehicle). Our objective is to autonomously count the number of agave plants in an area to aid management of the yield. An orthomosaic is obtained from agave plantations, which is then used to create a database. This database is in turn used to train a Convolutional Neural Network (CNN). The proposed method is based on computer image processing, and the CNN increases the detection performance of the approach. The main contribution of the present paper is to propose a method for agave plant detection with a high level of precision. In order to test the proposed method in a real agave plantation, we develop a UAV platform, which is equipped with several sensors to reach accurate counting. Therefore, our prototype can safely track a desired path to detect and count agave plants. For comparison purposes, we perform the same application using a simpler algorithm. The result shows that our proposed algorithm has better performance reaching an F1 score of 0.96 as opposed to 0.57 for the Haar algorithm. The obtained experimental results suggest that the proposed algorithm is robust and has considerable potential to help farmers manage agave agroecosystems.

Considering the lack of standard test methods for communication channels of modern unmanned aerial systems (UAS) class I and II, according to the UAS classification of the Armed Forces of Ukraine, it was decided to work out the basic approaches for determining indicators, conditions and procedure for conducting tests in this direction. The suggested methodological recommendations will improve the quality of the parameters and characteristics assessment for communication channels of UAS I and II classes. One of the distinctive trends in the development of modern forms and methods of conducting armed combat at all stages of the armed conflict is the widespread use of the UASs by opposing parties. UASs are capable of significant increasing the effectiveness of accomplishing aerial reconnaissance tasks, organizing electronic warfare, and providing real-time delivery of target pinpointing to fire means for the destruction of enemy’s manpower and material. A distinctive feature of UAS is that its external crew, as a rule, accomplish its mission at a considerable distance from the objects of attack. This fact significantly reduces the security risks and threats associated with performing combat missions under conditions of active enemy counteraction. Due to this feature, considerable attention is paid to the development of a reliable communication system that would be able to ensure task accomplishment at the maximum distance from command and control site. During the tests of UAS Class I and II, the specialists of the State Scientific Research Institute of Armament and Military Equipment Testing and Certification used testing methods of radio channels assessment, which will allow to improve the quality of UAS research of this type and give the manufacturers recommendations for increasing their capabilities.

Unmanned aerial systems (UAS, also known as UAV, RPAS or drones) have a great potential to support a wide variety of aerial remote sensing applications. Most UAS work by acquiring data using on-board sensors for later post-processing. Some require the data gathered to be downlinked to the ground in real-time. However, depending on the volume of data and the cost of the communications, this later option is not sustainable in the long term. This paper develops the concept of virtualizing super-computation on-board UAS, as a method to ease the operation by facilitating the downlink of high-level information products instead of raw data. Exploiting recent developments in miniaturized multi-core devices is the way to speed-up on-board computation. This hardware shall satisfy size, power and weight constraints. Several technologies are appearing with promising results for high performance computing on unmanned platforms, such as the 36 cores of the TILE-Gx36 by Tilera (now EZchip) or the 64 cores of the Epiphany-IV by Adapteva. The strategy for virtualizing super-computation on-board includes the benchmarking for hardware selection, the software architecture and the communications aware design. A parallelization strategy is given for the 36-core TILE-Gx36 for a UAS in a fire mission or in similar target-detection applications. The results are obtained for payload image processing algorithms and determine in real-time the data snapshot to gather and transfer to ground according to the needs of the mission, the processing time, and consumed watts.
