Special Issue Information

Dear Colleagues,

Sensor networks, Internet of Things (IoT), machine-to-machine (M2M) communications and smart-everything services play a more and more significant role in today’s social, economic, communication and technological landscape. Such connected systems belong to a large set of use-cases where smart sensors, innovative devices and advanced telecommunication infrastructures jointly work to ensure the desired service requirements defining new cutting-edge applications. In this context, the fifth generation of mobile communications (5G) introduced, since its initial definition stages, dedicated use-cases for Massive Machine-Type Communication (mMTC), such as smart cities, vehicular-to-vehicular communications, environmental and healthcare sensing, industry 4.0, etc., confirming the great interest and strategic role of these types of services.

Nonetheless, the expected large amount of devices and wide coverage required by such services can represent a challenge for terrestrial-only networks. Satellite Communication (SatCom), hybrid networks, next generation of smart satellites with onboard processing and smart satellite terminals can significantly help in supporting these types of services. Satellite network systems become essential in remote and isolated environments, offering global coverage while extending or replacing the terrestrial infrastructure capabilities enabling new and innovative fully connected environments.

The objective of this Special Issue is to provide an update on the current knowledge with state-of-the-art, theory and practical experiments on Sensors and Satellite Network Systems, allowing us to identify the market and technological innovation trends and the most promising solutions. This Special Issue welcomes original research articles presenting significant analysis, studies, simulations, experimentations and trials on these subjects, considering the perspectives of the various stakeholders (manufacturers, service provides, technology providers, network providers, satellite operators, etc.).

One of the main features of CubeSats is represented by their extreme versatility, e.g., maintaining the same overall structure for different purposes. This requires high technological flexibility achievable in a cost-effective way while maintaining compact sizes. In this contribution, a microwave receiver specifically designed for CubeSat applications is proposed. Due to the wide input operating bandwidth, i.e., 2 GHz–18 GHz, it can be exploited for different purposes, e.g., satellite communication, radars, and electronic warfare systems. This is beneficial for CubeSat systems, whereby the possibility to share the same front-end circuit for different purposes is a key feature in reducing the overall size and weight. The downconverter was designed to minimize the spurious contributions at low frequency by taking advantage, at the same time, of commercial off-the-shelf components due to their cost-effectiveness. The idea behind this work is to add flexibility to the CubeSat communication systems in order to be reusable in different contexts. This feature enables new applications but also provides the largest bandwidth if required from the ground system. An accurate experimental characterization was performed to validate the downconverter performance with the aim of allowing easy system integration for the new frontier of CubeSat technologies. This paves the way for the most effective implementation of the Internet of Things (IoT), machine-to-machine (M2M) communications, and smart-everything services. Full article

When managing a constellation of nanosatellites, one may leverage this structure to improve the mission’s quality-of-service (QoS) by optimally distributing the tasks during an orbit. In this sense, this research proposes an offline energy-aware task scheduling problem formulation regarding the specifics of constellations, by considering whether the tasks are individual, collective, or stimulated to be redundant. By providing such an optimization framework, the idea of estimating an offline task schedule can serve as a baseline for the constellation design phase. For example, given a particular orbit, from the simulation of an irradiance model, the engineer can estimate how the mission value is affected by the inclusion or exclusion of individuals objects. The proposed model, given in the form of a multi-objective mixed-integer linear programming model, is illustrated in this work for several illustrative scenarios considering different sets of tasks and constellations. We also perform an analysis of the Pareto-optimal frontier of the problem, identifying the feasible trade-off points between constellation and individual tasks. This information can be useful to the decision-maker (mission operator) when planning the behavior in orbit. Full article
