This paper describes development of automatic flight control system for an unmanned target drone which is operated by Korean army as for anti-air gun shooting training. Current target drone is operated by pilot control of on-board servo motor via remote control system. Automatic flight control system for the target drone greatly reduces work load of ground pilot and can increase application area of the drone. Most UAVs being operated now days use high-priced sensors as AHRS and IMU to measure the attitude, but those are costly. This paper introduces the development of low-cost automatic flight control system with low-cost sensors. The integrated automatic flight control system has been developed by integrating combining power module, switching module, monitoring module and RC receiver as an one module. The performance of automatic flight control system is verified by flight test.

Drones are controlled by the remote pilot from the ground stations using the radio control or autonomously following the pre-programmed flight plans. In this paper, we develop a method and an optimal path search system for providing 3D augmented reality flight (ARF) images for safe and efficient flight control of drones. The developed system consisted of the drone, the ground station and user terminals, and the optimal path search server. We use the Dijkstra algorithm to find the optimal path considering the drone information, flight information, environmental information, and flight mission. We generate a 3D augmented reality flight (ARF) image overlaid with the path information as well as the drone information and the flight information on the flight image received from the drone. The ARF image for adjusting the drone is generated by overlaying route information, drone information, flight information, and the like on the image captured by the drone.

2022년 말 수도권을 침범한 북한 드론 격추 실패의 논쟁 중심에는 안티드론(Anti Drone, 대(對) 드론)이 있다. 안티드론은 허가되지 않은 공역의 드론 비행을 탐지하여 제지하는 각종 수단이다. 안티드론 기술은 현재와 같은 다양한 드론의 위법 상황에서 반드시 필요한 드론 기술의 핵심 방어체계이다. 드론 역할이 증대된 우크라이나 전쟁에서 우리는 경각심을 가져야 한다. 방어가 쉽지 않은 드론 공격이 전쟁의 승패를 가름할 수도 있다. 세계 각국의 안티드론 기술 개발 경쟁은 상승하고 있다. 새로운 안티드론 기술이 나타나면 이를 뛰어넘는 드론이 개발된다. 본 연구는 국내 드론의 방어체계를 분석하여 안티드론 현황을 제시하였다.

A drone without attaching guns or bombs can be a dangerous weapon, since its motor speed is greater than 3000 rpm, which is similar to that of a mower powered by a LiPo battery. The anti-drone system is the only means of detecting and neutralizing drone attacks. Many defense companies around the world provide solutions using various types of equipment (for example, radar, cameras, jamming guns, and net guns). ETRI has also developed a Low-Altitude Drone Detection (LADD) system consisting of Ku-band radar and an Electro-Optical/Infra-Red (EO/IR) camera. In this paper, we summarize recent technical advances in anti-drone systems around the world and introduce the features and describe the performance of the LADD system.

This paper introduces an algorithm to middle-low price drone's autonomous navigation flight system using computer vision and GPS. Existing drone operative system mainly contains using methods such as, by inputting course of the path to the installed software of the particular drone in advance of the flight or following the signal that is transmitted from the controller. However, this paper introduces new algorithm that allows autonomous navigation flight system to locate specific place, specific shape of the place and specific space in an area that the user wishes to discover. Technology developed for military industry purpose was implemented on a lower-quality hobby drones without changing its hardware, and used this paper's algorithm to maximize the performance. Camera mounted on middle-low price drone will process the image which meets user's needs will look through and search for specific area of interest when the user inputs certain image of places it wishes to find. By using this algorithm, middle-low price drone's autonomous navigation flight system expect to be apply to a variety of industries.

The drone is an unmanned aerial vehicle which has no human pilot. Drones can be classified into military drones, commercial drones, and personal drones by usage. Also, drones can be classified from large-sized to nano-sized drone by size and autonomous, remote controlled drone by control type. Especially, military drones can be classified into low-altitude drones, medium-altitude, and high-altitude drones by altitude. Recently, the drone industry is one of the fast growing industries in the world. As drone technologies have become more advanced and cost-effective, Korean government has set its goal to become a top-level country in drone business. However, the government's strict regulation for drone operations is one of the biggest hurdles for the development of the related technologies in Korea and other countries. For example, critical problems for drone delivery can be classified into technical issues and institutional issues. Technical issues include durability, conditional awareness, grasp and release mechanisms, collision avoidance systems, drone operating system. Institutional issues include pilot and operator licensing, privacy rules, noise guidelines, security rules, education for drone police. This study analyzes the trends of the drone industry from the viewpoint of technology and regulation. Also, we define the business areas of drone utilization. Especially, the drone business types or models for public sector are proposed. Drone services or functions promoting public interests need to be aligned with the business reference model of Korean government. To define ten types of drone uses for public sector, we combine the business types of government with the future uses of drones that are proposed by futurists and business analysts. Future uses of drones can be divided into three sectors or services. First, drone services for public or military sectors include early warning systems, emergency services, news reporting, police drones, library drones, healthcare drones, travel drones. Second, drone services for commercial or industrial services include parcel delivery drones, gaming drones, sporting drones, farming and agriculture drones, ranching drones, robotic arm drones. Third, drone services for household sector include smart home drones.

There is an accelerating need for ocean sensing where autonomous vehicles can play a key role in assisting engineers, researcher and scientists with environmental monitoring and collecting oceanographic data. This paper is performed to develops an autonomous sailing drone to be used as a sensor carrying platform for autonomous data acquisition at Sea. From a sailing drone design viewpoint, it is important to establish reliable prediction methods for sailing drone's resistance. The required power for the propulsion unit depends on the ship resistance and speed. There are three solutions for the prediction of ship resistance as follow analytical methods, model tests in tanks and Computational Fluid Dynamics (CFD). The present paper aims at simulating sailing drone friction resistance using numerical method. The dynamic mesh motion is used to describe the sailing drone movement.

본 연구는 국가중요시설을 대상으로 대드론 통합방호체계 구축 시 고려사항을 도출하기 위한 영향요인에 대한 연구이다. 현재 드론 방호는 정부기관이나 군, 국가중요시설의 필요에 의해 시중에 개발된 드론 방호용 장비를 단편적으로 설치하여 운용하고 있다. 이러한 이유로 장비의 중복설치 또는 중첩 운용 등 자원의 낭비와 운용 간 제도적·법률적 문제점이 나타나고 있다. 이에 따라, 국가중요시설을 대상으로 효율적이고 체계적인 대드론 방호체계 구축에 미치는 영향요인을 식별하고자 하였다. 본 연구는 연구 목적과 범위를 고려하여 사례분석과 방호이론 연구, 관계 법령 분석을 통해 3가지의 영향요인과 12개의 세부 영향요인을 도출하였다. 본 연구의 결과를 토대로 향후 대드론 통합 방호체계 구축 시 고려사항으로 활용한다면, 모든 국가방위요소가 통합되어 각자의 역할에 따라 체계적인 대드론 통합방호가 가능하게 될 것이다. 이와 더불어, 대드론 통합방호체계 구축의 이론적 토대를 제공할 것이다. 본 연구의 2가지 연구 결과는 대드론 통합방호체계 구축을 위한 논리적이고 체계적인 영향요인을 제시하였다는 데에 연구의 가치가 있다.
