“…This capability ensures that communication remains uninterrupted, even in remote or challenging environments. Additionally, drones have the ability to transmit real-time video and audio data during emergencies, equipping rescue teams with critical information to make prompt and well-informed decisions [99]. Furthermore, drones are equipped with a diverse range of communication equipment, including radios, antennas, and satellite links.…”

The widespread interest in using drones in maritime transport has rapidly grown alongside the development of unmanned ships and drones. To stimulate growth and address the associated technical challenges, this paper systematically reviews the relevant research progress, classification, applications, technical challenges, and possible solutions related to the use of drones in the maritime sector. The findings provide an overview of the state of the art of the applications of drones in the maritime industry over the past 20 years and identify the existing problems and bottlenecks in this field. A new classification scheme is established based on their flight characteristics to aid in distinguishing drones’ applications in maritime transport. Further, this paper discusses the specific use cases and technical aspects of drones in maritime rescue, safety, navigation, environment, communication, and other aspects, providing in-depth guidance on the future development of different mainstream applications. Lastly, the challenges facing drones in these applications are identified, and the corresponding solutions are proposed to address them. This research offers pivotal insights and pertinent knowledge beneficial to various entities such as maritime regulatory bodies, shipping firms, academic institutions, and enterprises engaged in drone production. This paper makes new contributions in terms of the comprehensive analysis and discussion of the application of drones in maritime transport and the provision of guidance and support for promoting their further development and integration with intelligent transport.

“…Moreover, UAVs can also be used as relay points for land-sea networks, and network integration will extend to deep-sea communications. There have been many works on the research and application of atmosphere-ocean optical communication systems [11][12][13]. Reference [14] proposed that a communication link can be built among the ground station, UAV and high-speed train: passenger mobile data are transferred to the base station through the UAV relay, so the passengers can surf the internet through WIFI in the train.…”

The features of unmanned aerial vehicles (UAVs), such as strong manoeuvrability, small size, and light weight, make them considered to participate in free space optical (FSO) quantum communication, becoming an important part of the Space-Air-Ground Integrated Network. However, research reports on small-sized drones based long-range optical quantum link are few. A major challenge is that traditional opto-mechanical structure is difficult to adapt to small UAV platforms. Here, a lower size, weight, and power (SWaP) acquisition and tracking system prototype is developed, and its greatest advantage is that the system can be easily integrated into small flying platforms and quickly build a long-distance quantum communication link. The prototype weighs less than 8 kg. A small-sized two-axis mirror mechanism is designed for wide-range acquisition and tracking. Moreover, the system can automatically point to ground station. The SWaP acquisition and tracking system can support quantum key distribution (QKD) link and general FSO link by drones. In the 7 km air-to-ground demonstration, the acquisition and tracking system prototype is tested in practice, which is suspended under the small six-rotor UAV platform, and a special passive vibration isolation unit is added in between. A ten-minute continuous and stable beacon tracking proves that the system can quickly and automatically align.

“…Compared with ordinary UAVs, tethered UAVs have the advantages of long hovering times and abundant power and have broader application prospects. Due to these advantages, tethered UAVs are widely used in the fields of bridge safety detection [1], forest firefighting [2], and maritime emergency communication [3].…”

Tethered UAV is composed of a UAV platform, tethered cable and winch. The UAV platform and tethered cable are an interactive whole, and the movement of the UAV platform will change the configuration and tension of the tethered cable. Under extreme external conditions (such as strong airflow) or unprofessional operation, the UAV platform will be prone to extreme movement, which will impact the tethered cable, and in serious cases, the tethered UAV will not work normally. To study the influence on the tethered UAV due to impact, equations for the relation between impact stress and impact parameters are derived and numerically solved to determine the dangerous area of the tethered UAV based on two failure criteria. The obtained results reveal that a smaller elastic modulus and cross-sectional area will lead to less failure of the tethered UAV, and the breaking strength of the cable is vital to the tethered UAV when it is impacted. Engineering suggestions are also provided to make tethered UAVs safer. INDEX TERMSTethered UAV; Impact; Dangerous Area 42 experiments. Then, he evaluated the impact process, 43 possible damaged components, and failure modes of the 44 UAV at different angles and speeds. The obtained results 45 showed that under certain angles and speeds, the UAV 46 would be irreparably damaged after being hit, and the 47 UAV battery would be at risk of fire [7]. Eamon T et al. 48 estimated the range of injury risks to humans due to the 49 unmanned aerial system (UAS) impact, and live flight 50 tests were observed to be less severe than falling impact 51 tests [8]. Meng et al. simulated the dynamic response of 52 the horizontal stabilizer during UAS airborne collision, 53 and the obtained results showed that the UAV impact at 54 the airliner cruising speed may cause some damage to
