Support For Unmanned Aerial Vehicles Research Articles

Digitization of the UAV flight task for processing fields in precision agriculture

The article discusses an approach aimed at the development of algorithmic support for unmanned aerial vehicles. This is due to the construction of a flight task based on the optimality criterion for solving the problem of processing fields in precision farming. The shortest path criterion is used in the implementation of the UAV flight plan with a complex trajectory and frequent course changes. Dijkstra’s algorithm is considered as an algorithm that implements this criterion. The article provides an example of calculating a segment of a network of objects, notes the simplicity of the calculations of the algorithm. Suggestions on the use of this algorithm in the construction of a flight task are given.

RESEARCH ON THE DIGITAL RETENTION MECHANISM OF TIBETAN BUDDHISM ARCHITECTURE BASED ON UAV AND TLS: A CASE STUDY OF BAOGUANG HALL

Abstract. Tibetan Buddhist architecture embodies ancient Chinese architectural culture and religious culture. In the past, the information retention mechanisms for ancient buildings were implemented as photos, tracings, and rubbings, which cannot fundamentally document the authenticity of architectural heritage. To explore the digital retention method for the unique style of Han Tibetan architecture，this research that based on the idea of reverse documentation first collects point cloud data with the technical support of unmanned aerial vehicle (UAV) photogrammetry and terrestrial laser scanner (TLS) and then uses registration method to obtain the integral of the point cloud model of Baoguang Hall. This paper explores the possibility of extracting 2D and 3D information, such as architectural plans, facades, decorative components, and models of the temple architecture, by processing point cloud data. Finally, this study proves the feasibility of using digital technology for the preservation and protection of architectural heritage.

Supporting Unmanned Aerial Vehicle Services in 5G Networks: New High-Level Architecture Integrating 5G With U-Space

To provide efficient, safe, and secure access to the airspace, the European Union has launched a set of new services called U-space that allow for the support of unmanned aerial vehicle (UAV) management and conflict prevention for flights in the airspace. These services are based on communication technology, which is expected to be the key enabler to unlock the underlying potential of UAV operations. In this regard, the 5G mobile network is envisioned to be the communication standard to support diverse UAV operations and applications. In this article, we propose a novel architecture that integrates 5G systems (5GSs) with U-space. The main aim consists of providing a reference design that demonstrates how 5G can support U-space services and shows the interactions among different stakeholders. Further, we introduce the 5G!Drones project, which relies on the proposed architecture to test UAV use-case scenarios on top of the 5G infrastructure.

5G and the Need for Platform Integrity

Current cellular architecture will not be suitable for 5G because it will not scale to the anticipated number of connected endpoints and their rich diversity. The distribution of the previously centralized Core Network (CN) functionality, e.g., Access Authentication and Authorization, has to be decentralized, leading to the demise of the most utilized tool of network security engineering, Physical Security Perimeter. The asserted and attested Platform Integrity of the network nodes that comprise the edges of the network, the network cloud, “network fog”, and the endpoints will allow mobile network operators (MNOs) to create Virtual Network Perimeters and allow highly reliable, diverse, and flexible 5G networks. This article describes the reasons for such network transformation, provides references to applicable standardization activities, and uses the examples of support for Unmanned Aerial Vehicles (UAV) and connected automobiles by 5G networks to justify the need for Platform Integrity.
