“…), and land applications (e.g., soil moisture indices, vegetation monitoring, classification, fire fractional cover, fraction of vegetation over land, landslides and motion risk assessment, permafrost, and others) to support the environment management, with resolutions comparable to those of optical systems. The manufacturing and implementation related to a small SAR satellite mission have opened a market for a new technology which has recently been developed: the constellations of small SAR satellites, being the principle of Fractionated and Federated Satellites (FSS) [71], and/or bistatic SARs as companion satellites (e.g., SAOCOM [72]).…”

An optimal payload selection conducted in the frame of the H2020 ONION project (id 687490) is presented based on the ability to cover the observation needs of the Copernicus system in the time period 2020–2030. Payload selection is constrained by the variables that can be measured, the power consumption, and weight of the instrument, and the required accuracy and spatial resolution (horizontal or vertical). It involved 20 measurements with observation gaps according to the user requirements that were detected in the top 10 use cases in the scope of Copernicus space infrastructure, 9 potential applied technologies, and 39 available commercial platforms. Additional Earth Observation (EO) infrastructures are proposed to reduce measurements gaps, based on a weighting system that assigned high relevance for measurements associated to Marine for Weather Forecast over Polar Regions. This study concludes with a rank and mapping of the potential technologies and the suitable commercial platforms to cover most of the requirements of the top ten use cases, analyzing the Marine for Weather Forecast, Sea Ice Monitoring, Fishing Pressure, and Agriculture and Forestry: Hydric stress as the priority use cases.

“…For that reason, a scenario that can provide relevant results needs to be conceived. As previously presented, the EO community has a great interest in developing satellite missions to monitor the Arctic region [1], [5]. Therefore, a scenario based on this type of mission would demonstrate the benefits of the OSADP in future EO missions.…”

A Novel Dissemination Protocol to Deploy Opportunistic Services in Federated Satellite Systems

Earth Observation applications are demanding higher spatial resolution and shorter revisit times than existing systems, which can be met by ad-hoc constellations of Federated Satellite Systems. These systems are distributed satellite architectures which rely on the collaboration between satellites that share unused resources, such as memory storage, computing capabilities, or downlink opportunities. In the same context, the Internet of Satellites paradigm expands the federation concept to a multi-hop scenario, without predefining a particular satellite system architecture, and deploying temporal satellite networks. The basis of both concepts is the offer of unused satellite resources as services. Therefore, it is necessary that satellites notify their availability to the other satellites that compose the system. This work presents a novel Opportunistic Service Availability Dissemination Protocol, which allows a satellite to publish an available service to be consumed by others. Details of the protocol behavior, and packet formats are presented as part of the protocol definition. The protocol has been verified in a realistic scenario composed of Earth Observation satellites, and the Telesat mega-constellation as network backbone. The achieved results demonstrate the benefits of using a protocol as the proposed one, which in some cases even doubles the amount of data that can be downloaded. To the best of our knowledge, this proposal is the first protocol that allows deploying opportunistic services for Federated Satellite Systems.

“…Hence, it is envisioned as a fundamental component of bolstering Space Information Network (SIN) applications. In recent years, numerous countries started to attach importance to LRS-SN, as exemplified by Russia's Gosudarevo Oko (known as Sovereign's Eye) and by the Horizon 2020 Operational Network of Individual Observation Nodes (ONION) project of the European Union [1], as well as by the Gaofen-1 to Gaofen-6 of China and the Planet Labs sensing remote satellites group. However, the LRS-SN exhibits a time-varying topology, intermittent ISLs and limited on-board resources.…”

The Low earth orbit Remote Sensing (LRS) satellite network is envisioned as an essential component of bolstering space information applications, thus extending conventional ground information applications to the on-board space information applications. However, it inevitably faces grave challenges imposed by the dynamics of the satellite network's topology, by the intermittence of Inter-Satellite communication Links (ISLs) as well as by the mobility-induced satellite-access switching of mobile terminals. Hence, this is a very different networking landscape from that of the terrestrial Internet. Against these challenging problems, we propose a resilient networking architecture for LRS Satellite Networks (LRS-SNs), with special emphasis on their dynamic routing, resilient transmission and their intrinsic mobility. Specifically, path-quality aided and lifetimeaware dynamic routing is proposed for enhancing the routing against dynamic topology changes. Hop-by-hop data transmission is relied upon for providing transmission resilience against ISL intermittence. Furthermore, data caching is invoked for providing resilience against intermittent communications imposed by dynamic satellite access switching. We employ on semi-physical simulation platform for evaluating the achievable performance of the proposed resilient network architecture.
