According to forecasts, around 10 billion connected devices in the world will exchange data over the Internet by2028 and the significant connections increase threatens to congest terrestrial networks. These devices will mainly beembedded, controlled by smart software and operated in the cloud, integrating the Internet of Things ecosystem. Addi-tionally, current terrestrial infrastructures do not meet novel IoT requirements: remote access areas, multiple networkdomains crossing and adaptable latency and bandwidth. To provide global and ubiquitous coverage, the 3GPP stan-dardizes in rel-17 the concept of Non-Terrestrial-Networks. The term includes, among others, Non-Terrestrial nodessuch as GEO, MEO and LEO satellites. Lately, LEO satellites have contributed to consolidate the New Space indus-try opening new business opportunities by providing services using low-cost CubeSats. Despite offering importantbenefits compared to GEO (e.g. lower latency and propagation loss), LEO still has challenges to face related to com-munication discontinuity (intermittent satellite-to-ground links). Global region coverage is achieved through satelliteconstellations; however, the main concern is the non-guarantee of simultaneous contact from UE to the Ground StationNetwork via the satellite. While 3GPP rel-17 specs have centered on the specification of satellites using transparentpayload, the use of regenerative payloads has not precluded and has a central role in the technology roadmap. Re-generative payloads envision to embark part of the NF within the satellite, giving multiple enhancements (e.g. lowerlatencies, Store-and-Forward operation, in-satellite local loop communications and edge computing). Onboard func-tions may include radio access functions, such as eNB/gNB, as well as core NF, which enables direct satellite responseto UE. This paper provides a performance analysis of a deployment of core NF in a regenerative payload with a Soft-ware Defined Radio based on FPGA technology for nanosatellites. Measures are obtained and contrasted against aRPi4 board by running a tailored Evolved Packet Core (EPC) with NB-IoT NTN support.

Enabling multi-tenant cellular IoT services over LEO constellations in future 6G networks
Kellermann, Timo Nicolas; Calveras Augé, Anna M.; Pueyo Centelles, Roger; Camps, Dani; Ferrús Ferré, Ramón Antonio; Guadalupi, Marco
Satellite-based, non-terrestrial networks (NTN) are crucial in providing global connectivity coverage, supporting important use cases in future 3rd Generation Partnership Project (3GPP) 6th generation networks (6G). Existing systems stand out due to their high complexity and specialized user equipment (UE) that comes with high operational costs. The rise of CubeSat and SmallSat spacecraft technology drastically cuts the cost of deployment, especially in Low Earth Orbits (LEO). Possible access architectures for NTN include repeater-like architectures with transparent payloads, where the gNB/eNB is located on the ground segment, or regenerative payloads, with a full gNB/eNB located on the satellite. A key NTN service is expected to be based on the extension of the NB-IoT (NarrowBand Internet of Things) protocol deployed over low-density LEO constellations using regenerative payloads, that are able to operate without having an active feeder link connection with a ground station. Enabling this service requires solving two key architectural challenges, namely the operation of the NB-IoT protocol in store and forward mode and supporting multi-tenancy, with multiples service providers using the same LEO constellation to extend their service footprint. The main contribution of this paper is the capacity analysis of a revised 3GPP architecture for NB-IoT services with a regenerative NTN architecture supporting discontinuous service and feeder link connectivity, by adding store and forward functionality. The assesment is supported by analysing the information flow of the revised architecture. Based on that architecture, we present a practical NB-IoT constellation and provide a capacity analysis. That constellation enabling for NB-IoT coverage across the globe may be possible with as little as one satellite, assuming its orbit covers the whole globe. Furthermore, we analyze authentication and user data transport with the maximum number of supported UE per satellite due to capacity constraints in the feeder link under typical data patterns. We find that variations in revisit and visibility times for both UEs and ground stations significantly impact the maximum number of supported users. Finally, the paper points out that new architectures for discontinuous backhauling, as one of the key NTN challenges, must be solved by future 6G networks.

FSSCat, the “Federated Satellite Systems/ 3 Cat-5” mission was the winner of the 2017 ESA S^3 (Sentinel Small Satellite) Challenge and overall winner of the Copernicus Masters competition. FSSCat consists of two 6 unit cubesats carrying on board UPC's Flexible Microwave Payload - 2 (FMPL-2), an L-band microwave radiometer and GNSS-Reflectometer implemented in a software defined radio, and Cosine's HyperScout-2 visible and near infrared + thermal infrared hyperspectral imager, enhanced with PhiSat-1, a on board Artificial intelligence experiment for cloud detection. Both spacecrafts include optical and UHF inter-satellite links technology demonstrators, provided by Golbriak Space and UPC, respectively. This paper describes the mission, and the main scientific results of the FMPL-2 obtained during the first three months of the mission, notably the sea ice concentration and thickness, and the downscaled soil moisture products over the Northern hemisphere.

Cooperative, Connected and Automated Mobility (CCAM) services require precise and reliable localization services able to infer and track the position of a vehicle with lane accuracy. The H2020 5GCroCo project, which trials 5G technologies in the European cross-border corridor along France, Germany and Luxembourg, as well as in five small-scale trial sites, considers different technologies to enhance vehicle localization, including GPS-Real Time Kinematic (GPS-RTK), Ultra-WideBand (UWB) and Inertial Sensors (INS). This paper presents a compact prototype, which integrates these localization technologies with 5GCroCo’s On-Board Unit (OBU) equipment, and its evaluation within the scope of the Anticipated Cooperative Collision Avoidance (ACCA) Use Case demonstrated in Barcelona small-scale trial site.

With the advent of Connected and Autonomous Vehicles (CAVs) comes the very real risk that these vehicles will be exposed to cyber-attacks by exploiting various vulnerabilities. This paper gives a technical overview of the H2020 CARAMEL project (currently in the intermediate stage) in which Artificial Intelligent (AI)-based cybersecurity for CAVs is the main goal. Most of the possible scenarios are considered, by which an adversary can generate attacks on CAVs, such as attacks on camera sensors, GPS location, Vehicle to Everything (V2X) message transmission, the vehicle’s On-Board Unit (OBU), etc. The counter-measures to these attacks and vulnerabilities are presented via the current results in the CARAMEL project achieved by implementing the designed security algorithms.

Demonstration of the federated satellite systems concept for future earth observation satellite missions

In the last years, the need to access Earth Observation high spatial resolution data with very low latency, ideally in near-real-time, has increased. Distributed Satellite Systems have emerged as an effective and efficient architecture to deal with these tight requirements. One of these systems is the Federated Satellite Systems which explore the benefits of sharing unused and available resources between satellites, such as memory storage or downlink opportunities. This interaction is known as satellite federations. Additional downlink contacts may enable low-latency communications and increase the downlink capacity. Therefore, the deployment of federations would allow satisfying current Earth Observation community demands. This work contributes to establish this promising paradigm by presenting a proof-of-concept of a federated system, called FSS Experiment payload. This payload is boarded into three stratospheric balloons, and it provides them communications means to create federations. The design of the payload, and the flight campaign results are presented in this work. These results demonstrate the feasibility of deploying federations, as well as the benefits of deploying them in future EO missions.

Evaluation of LoRa for data retrieval of ocean monitoring sensors with LEO satellites
Fernandez Capon, Lara Pilar; Ruiz De Azúa Ortega, Juan Adrián; Calveras Augé, Anna M.; Camps Carmona, Adriano José
The celebration of the International Polar Year in 2007 remarked the necessity to better monitor the polar regions. Moreover, the H2020 “Operational Network of Individual Observation Nodes” (ONION) project analyzed and proposed an overall EU strategy and technical guidelines to develop and implement innovative Earth Observation concepts in the time frame 2021-2027. The top priority that was identified was the Maritime Weather Forecast, and in particular the Arctic sea ice monitoring use-case. Currently, those needs have been addressed with remote sensing satellites or in-situ instruments. However, in-situ instruments often sink or crash with ice blocks. Additionally, these instruments are isolated, making challenging its deployment and the data retrieval, using LEO satellite communications (e.g. Iridium, OrbComm). This also poses a problem in terms of modularity and flexibility, since sensors rely on proprietary communication systems. This work proposes a modular and cost-effective solution to this problem applying the paradigm of the Internet of Things to this context. Particularly, Long Range (LoRa) is one of the most frequently used and efficient technologies that also ensures long ranges. As part of the presented work, a satellite constellation is proposed, analyzed to cover the Arctic region. The maximum number of sensors simultaneously using the LoRa technology is also evaluated.

The main goals of the CARAMEL project are to enhance the protection of modern vehicles against cybersecurity threats related to automated driving, smart charging of Electric Vehicles, and communication among vehicles or between vehicles and the roadside infrastructure. This work focuses on the latter and presents the CARAMEL architecture for improving the security and privacy of communication for connected and au- tonomous driving. The proposed architecture includes: (i) multi- radio access technology capabilities, with simultaneous 802.11p and LTE-Uu support; (ii) a MEC platform, where algorithms for detecting attacks are implemented; (iii) an intelligent On- Board Unit with anti-hacking features inside the vehicle; (iv) a Public Key Infrastructure that validates in real-time the integrity of vehicle’s data transmissions. As an indicative application scenario, the interaction between the entities of the CARAMEL architecture is showcased in the case that the GPS locations used by vehicles are spoofed.
