Enabling 5G on the Ocean: A Hybrid Satellite-UAV-Terrestrial Network Solution

Current fifth generation (5G) cellular networks mainly focus on the terrestrial scenario. Due to the difficulty of deploying communications infrastructure on the ocean, the performance of existing maritime communication networks (MCNs) is far behind 5G. This problem can be solved by using unmanned aerial vehicles (UAVs) as agile aerial platforms to enable on-demand maritime coverage, as a supplement to marine satellites and shore-based terrestrial based stations (TBSs). In this paper, we study the integration of UAVs with existing MCNs, and investigate the potential gains of hybrid satellite-UAV-terrestrial networks for maritime coverage. Unlike the terrestrial scenario, vessels on the ocean keep to sea lanes and are sparsely distributed. This provides new opportunities to ease the scheduling of UAVs. Also, new challenges arise due to the more complicated maritime prorogation environment, as well as the mutual interference between UAVs and existing satellites/TBSs. We discuss these issues and show possible solutions considering practical constraints

A lightweight prototype of a magnetometric system for unmanned aerial vehicles

Detection of the Earth’s magnetic field anomalies is the basis of many types of studies in the field of earth sciences and archaeology. These surveys require different ways to carry out the measures but they have in common that they can be very tiring or expensive. There are now several lightweight commercially available magnetic sensors that allow light-UAVs to be equipped to perform airborne measurements for a wide range of scenarios. In this work, the realization and functioning of an airborne magnetometer prototype were presented and discussed. Tests and measures for the validation of the experimental setup for some applications were reported. The flight sessions, appropriately programmed for different types of measurements, made it possible to evaluate the performance of this detection methodology, highlighting the advantages and drawbacks or limitations and future developments. From the results obtained it was possible to verify that the measurement system is capable of carrying out local and potentially archaeological magnetometric measurements with the necessary precautions

Fire Scout: The Navy, Northrop Grumman, and Acquisition in Adversity: A Case Study

The Department of Defense is experimenting with how to deliver new capabilities in 2 to 5 years. Program offices recognize that they are dependent upon their contractors for successful delivery. The MQ-8 Fire Scout started in 1999 and achieved initial operational capability of the MQ-8C in 2019, after 20 years and effectively three program restarts. After each restart, the contractor developed, manufactured, and delivered a functional product deployed by the Navy within 5 years of contract award. Conventional wisdom says that senior leadership support and customer urgency are critical to fast delivery. This study shows how a program office and prime contractor were able to deliver a new capability despite changes in procurement objectives, evolving technologies, and requirements.Prepared for the Naval Postgraduate School, Monterey, CA 93943.Naval Postgraduate SchoolApproved for public release; distribution is unlimited.Approved for public release; distribution is unlimited

U.S. Unmanned Aerial Vehicles (UAVS) and Network Centric Warfare (NCW) impacts on combat aviation tactics from Gulf War I through 2007 Iraq

Unmanned, aerial vehicles (UAVs) are an increasingly important element of many modern militaries. Their success on battlefields in Afghanistan, Iraq, and around the globe has driven demand for a variety of types of unmanned vehicles. Their proven value consists in low risk and low cost, and their capabilities include persistent surveillance, tactical and combat reconnaissance, resilience, and dynamic re-tasking. This research evaluates past, current, and possible future operating environments for several UAV platforms to survey the changing dynamics of combat-aviation tactics and make recommendations regarding UAV employment scenarios to the Turkish military. While UAVs have already established their importance in military operations, ongoing evaluations of UAV operating environments, capabilities, technologies, concepts, and organizational issues inform the development of future systems. To what extent will UAV capabilities increasingly define tomorrow's missions, requirements, and results in surveillance and combat tactics? Integrating UAVs and concepts of operations (CONOPS) on future battlefields is an emergent science. Managing a transition from manned- to unmanned and remotely piloted aviation platforms involves new technological complexity and new aviation personnel roles, especially for combat pilots. Managing a UAV military transformation involves cultural change, which can be measured in decades.http://archive.org/details/usunmannedaerial109454211Turkish Air Force authors.Approved for public release; distribution is unlimited

Innovation, technology and security: the emergence of Unmanned Aerial Vehicles before and after 9/11

This thesis addresses the relationship between military technological innovation and evolving practices of security before and after 9/11 through the case of unmanned aerial vehicle (UAV) technology and particularly the UAV lineage associated with the General Atomics Predator system. Through the case of UAV development the thesis contributes to wider theoretical debates regarding military innovation and weapons acquisition processes. The case illustrates that rather than a moment, innovation is better understood as a process. Rather than linear, however, the process is uncertain, involving complex interactions between institutional pressures, technological development and external events. The thesis presents UAV development in terms of ‘statuses’ of marginality, emergence and assimilation. Establishing the long UAV development history in the US, the thesis explores military innovation theory to consider the reasons for their long Cold War marginality, despite repeated efforts. It then considers the emergence of UAVs in the early post-Cold war period, focusing particularly on the design iterations that yielded the Predator and the bureaucratic political processes through which that system was fielded. Thirdly, the progressive assimilation of Predator is addressed in relation to the growing threat of terrorist networks, and the post-9/11 attempt to reorient existing military and intelligence capabilities to counter terrorism and counter insurgency operations. This raises the question of the relation between technological innovation and the security ‘pathways’ opened up after 9/11, the extent that 9/11 provided a window of opportunity for drone assimilation, and the role of drones in shaping the emergence of a technologically-enabled, remote approach to counter terrorism and military intervention

Multimission Aircraft Design Study-Operational Scenarios

In the most recent years, the Command, Control and Communications, Counter Measures, Intelligence, Surveillance and Reconnaissance (C3CMISR) aircrafts are used commonly in many NATO and UN Operations around the world. These aircrafts are AWACS, JSTARS, Rivet Joint, Compass Call and ABCCC. They provide close air support in the name of airborne surveillance, ground moving target surveillance, target reconnaissance, jamming, and command, control and communications issues in operational environments. Those aircrafts are tasked with a wide variety of missions than ever before in operational theaters and each one of them comprises a specific amount of cost and risk factors. As a new vision, while replacing the existing legacy systems, multi-mission architectures are taken into consideration for the C3CMISR missions. The stated objective is designing a one tail number Multi-Mission Aircraft (MMA) that includes all the C3CMISR tasks on one airframe. This study seeks some comments and advises about the MMA design technical feasibility. In order to search for these comments, four notional operational scenarios are created. First of all existing C3CMISR aircrafts are considered and evaluated in these operational scenarios and then different MMA architectures are defined and compared with the legacy systems in the name of adequacy
