“…Among the many benefits of such formation, satellites do not require complex transfer maneuvers if launched from the same vector. Also, since satellites perceive similar gravitational perturbations, significant savings in propellant for formation-keeping can be made [68]. From a communications perspective, the topological stability of this formation also favors the simplicity of fixed antennas against complex gimbal mounts or electronically steered antennas for ISLs.…”

Existing Internet protocols assume persistent end-to-end connectivity, which cannot be guaranteed in disruptive and high-latency space environments. To operate over these challenging networks, a store-carry-and-forward communication architecture called Delay/Disruption Tolerant Networking (DTN) has been proposed. This work provides the first examination of the performance and robustness of Contact Graph Routing (CGR) algorithm, the state-of-the-art routing scheme for space-based DTNs. To this end, after a thorough description of CGR, two appealing satellite constellations are proposed and evaluated by means of simulations. Indeed, the DtnSim simulator is introduced as another relevant contribution of this work. Results enabled the authors to identify existing CGR weaknesses and enhancement opportunities.

“…Consequently, the development of an aerospace culture associated with the development of capacities, in particular the design and development of networked satellite systems, such as constellations with low-cost satellites (Yoon et al, 2014), will significantly contribute to the sustainable use of resources and the protection of Colombian society (Corredor-Gutiérrez, 2017;Ximenes et al, 2019).…”

El desarrollo de las zonas rurales de Colombia y su conexión con las áreas urbanas ha sido uno de los grandes desafíos para garantizar una presencia efectiva del Estado en el territorio. Como parte de las alternativas para potenciar el desarrollo integral de la infraestructura y las comunidades rurales, se han propuesto opciones para la prestación de servicios aeroes- paciales que ofrecen medios de comunicación permanentes y herramientas para la observación terrestre, asistencia ante los efectos de fenómenos climáticos, cuantificación demográfica, control de áreas y poblaciones, y la determinación de rutas y vías de acceso, entre otras. A partir de ello, se propone una metodología para el análisis, diseño, desarrollo, implementación y evaluación de un proyecto espacial, que incluye el cálculo de condiciones operacionales y elementos orbitales, parámetros de desempeño, áreas de cobertura, número de aviones y satélites, y varios modelos de constelaciones de satélites dentro del territorio nacional. Esta propuesta busca identificar diferentes alternativas para el diseño y uso de equipos satelitales, con el fin de formular planes estratégicos a nivel estatal que permitan la apropiación de las tecnologías aeroespaciales, ofreciendo servicios equiparables al nivel de acceso a las comunicaciones y la observación terrestre, como medio para la planificación de políticas públicas orientadas a mejorar la conectividad y las capacidades tecnológicas de Colombia.

“…The results in [100] showed that using massive MIMO for C2C links improves the communication time; however, the use of massive MIMO increases the size of the CubeSats and the power consumption. A swarm of four CubeSats was developed in [101], which demonstrates multipoint to multipoint high data rates C2C links. S-band frequencies are used in [101] achieving 1 Mbps downlink, and 100 kbps crosslink data rates.…”

The research in the emerging space industry is becoming more and more attractive, given the increasing number of space-related applications. One primary entity of current space research is the design of miniaturized satellites, known as CubeSats, due to their numerous applications and low design and deployment cost. The new paradigm of connected space through CubeSats enables a wide range of applications such as Earth remote sensing, space exploration, and rural connectivity. CubeSats further provide a complimentary connectivity solution to the pervasive Internet of things (IoT) networks, leading to a globally connected cyber-physical system. This paper presents a holistic overview of different aspects of CubeSat missions, and provides a thorough review on the topic, both from academic and industrial perspectives. We further present the recent advances in the area of CubeSats communications with an emphasis on constellation and coverage issues, channel modeling, modulation and coding, and networking. The paper finally identifies several future research directions on CubeSats communications, namely Internet of space things, low power long range networks, machine learning for resource allocation in CubeSats, etc.
