Next Generation Smart RF Transceivers Modules

Critical applications such as wireless communications, terrestrial and flying radar, “smart-skin” conformal sensors, massively scalable “tile-by-tile” RFID-enabled reconfigurable intelligent surfaces are based on the use of transceivers (T/R).

The current Industrial technology is based on devices from GaAs that are hybridly connected to an antenna via a switching system, but it cannot satisfy upcoming applications such as 5G, IoT, autonomous vehicles, new generation radar with "active phase antenna" having upgraded requirements such as higher power, higher operating frequency, lower footprint and volume, enhanced functionality and lower costs. The new GaN technology due to its versatility superior properties of the material allows signal amplification at higher frequencies and smaller circuit area. To this end, Hellenic Naval Academy in cooperation with the Foundation for Research and Technology of Crete is participating in the "Heterogeneous Three-dimensional Integration using innovative nanotechnologies for the new generation of microwave transceivers" Operational Program. The main research activity of this project is into the new generation of configurable "smart" microwave transceivers by combining nanotechnology with micro/nanoelectronics and pioneering 2D and 3D heterogeneous integration, creating products with increased functionality for applications from future 5G wireless networks to upcoming radars.

Regarding the system-level solution for ultra-low-cost mass production of Millimeter-Wave modules for communication, the future trends include inkjet-/3D-printed antennas and sensors fabricated on glass or paper or other wearable/flexible substrates. All these have been introduced by Prof. Tentzeris from Georgia Tech who collaborates with Hellenic Naval Academy providing technical advice about future sensors, shape-changing 4D-printed wireless structures, mmW wearable antennas and RF modules.

Shipborne Small Tactical UAS (Aliaca)

World security starts with the protection of the oceans, an open space lightly regulated. The maritime environment is changing, bringing new sources of threats which are driving Navies to find solutions able to fulfill their operations efficiency by using multi-missions tools. However, to conduct an airborne maritime surveillance and coastal operations starting from a military vessel, navies around the world have to prioritize between vessel size, trained personnel availability and logistic.

SURVEY Copter, an Airbus subsidiary and a pioneer in small tactical UAS, designed the Aliaca system, with those priorities and constraints in mind.

With a fully autonomous net interception to board, the Aliaca, even during severe wind conditions and on every type of vessel, equipped or not with helicopter pads can be operated. Airborne ISR missions are now possible up to 30nm range and during 3 hours. The GX5 optronical payload, equipped with both day and night sensors, along with a silent electric propulsion system allows day/night operations to monitor point of interest while reducing drastically the possibility of being detected by unwanted parties. Easily deployed in less than 15 minutes, the Aliaca only requires two personnel to be implemented. The intuitive, responsive and user-friendly interface allows maritime and coastal operations conducted with ease to focus only on operational theater. The latest target detection system from both static and moving unidentified objects associated with geo referenced datas on the Ground Control System give to operators any decision making inputs necessary to conduct a successful mission. Training to operate such system is designed in a way so that every crew member onboard, even non-UAS specialized personnel can operate it easily.

Thanks to a decade of experience in the UAS maritime domain, and a recognized expertise through a contract award from the French Navy, the shipborne small Tactical UAS Aliaca enables new airborne capabilities to navies in need of ISR decision making tools while offering an advanced and robust platform able to conduct maritime and coastal operations.

Fixed-wing mini-UAVs, optimal tool for the Navies

By: Olivier Yvon, Grupo CPS Madrid

Abstract

Navies are more and more realizing that fixed-wing mini-UAV can provide them maritime surveillance and reconnaissance capabilities through high performance in range, endurance and take-off weight as well as easiness to launch from and recover on-board of most types of ships (under 40 meters) and low cost of acquisition and maintenance (low Life-Cycle-Cost). The main European Navies including France, Spain and UK have kicked-off a program of acquisition of such technologies.

Like the Vertical Take-Off and Landing UAVs but at a cheaper cost, the fixed-wing mini-UAV can be operated from the deck of the ships thanks to a small launcher catapult and an automatic recovery net that can be folded after use to minimize the logistic footprint.

A well-proven European UAV like FULMAR can offer 12 hours of endurance, 120 kms of range (RF LOS) and 30kgs of take-off weight. With a payload of EO/IR cameras, AIS and a mode S transponder, it can cover large areas at sea even in bad weather (winds up to 40 Knots). FULMAR is currently undertaking the type certificate process (under the European 1000MILST461 norm) and is expected to obtain it in during 2022.

In addition, the aerial vehicle is integrated in a complete UAS with control system enhanced with big data analytics and Artificial Intelligence as well as Low-Earth-Orbit encrypted satellite communications.
