Available in PDF, EPUB and Kindle. Book excerpt: A CubeSat is a miniaturized modular satellite that can be constructed from off-the-shelf components. With advancements in digital signal processing, power electronics, and packaging technology, it is feasible to fit science instruments and communication devices that were traditionally carried on larger satellites on CubeSat consolations. This not only reduces mission cost, repair, risk, but also provides more precise and real-time science data. Their low cost and versatility allow for CubeSats to be used to test technologies that are planned to use on larger satellites, to collect point-to-point data in space when launched as CubeSat constellations, or to monitor health of larger spacecrafts. This comprehensive reference explores CubeSat standards, launching methods, and detailed design guidelines for antennas specially made for CubeSat applications. Deployed CubeSat antennas, such as low gain antennas, high gain wire-based antennas, and horn and dish antennas as they relate to the technology are explored. Conformal CubeSat Antennas, including those that are independent of CubeSats and those integrated in CubeSat solar panels, are discussed. An antenna design guideline is provided to demonstrate the basics of a CubeSat link budget, which is transitionally published in signal and system community. Written by an expert in the field, this book enables readers to read antenna specifics when choosing communication front-end.

Book Synopsis X-band Antenna for CubeSat Satellite by : Joana Maria Llull Coll
Download or read book X-band Antenna for CubeSat Satellite written by Joana Maria Llull Coll and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This project describes the process of design and manufacturing of an X-Band (7.1-8.5 GHz) antenna for a CubeSat satellite, facing many of the design criteria and challenges of pico-satellites. A CubeSat is a type of miniaturized satellite for space research that is made up of multiples of 10×10×10 cm cubic units and has a mass of no more than 1.33 kilograms per unit. It can be manufactured using commercial off-the-shelf (COTS) components for its electronics and structure. Limited size, low mass, circular polarization, high gain and wide bandwidth are the main challenges of the antenna design. A design of an aperture-coupled patch antenna has been performed to overcome the difficulties and fulfill all the requirements for CubeSats antennas. The antenna consists of one or two rectangular patches, fed by a microstrip line through a crossed slot in the ground plane. The two patches are separated from the ground plane using a layer of hard, low-permittivity foam. After the study of several antenna models, a stacked patch antenna (two patches) accomplished most of the requirements. The antenna models have been simulated using a 3-D electromagnetic simulation software, HFSS. Simulation and measured results show a gain within 6-10dB, very good circular polarization, a good matching in the whole frequency band and accomplish dimension criterias for CubeSat antennas.

Book Synopsis Numerical Synthesis Algorithms and Antenna Designs for Next Generation Spaceborne Wind Scatterometer and CubeSat Antennas by : Jordan Budhu
Download or read book Numerical Synthesis Algorithms and Antenna Designs for Next Generation Spaceborne Wind Scatterometer and CubeSat Antennas written by Jordan Budhu and published by . This book was released on 2018 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two novel aperture type antennas, both for next-generation space borne applications, are designed. The first is 3D printed, all-dielectric, inhomogeneous, shaped lens antenna designed to produce a conically scanned spinning spot beam. The electronic scan stems from a ring of feeds located along the ring focus designed into the azimuthally symmetric lens. The antenna is proposed for use in a space-borne scatterometer used to measure wind speeds upon the surface of the earth's oceans. The design requires the advent of a complex code hybridizing the Computational Electromagnetics method of Geometrical Optics with the optimization strategy of Particle Swarm Optimization. This code and its mathematical formulations, the resultant designs, and the measurements validating the codes and obtained designs are presented in this dissertation. The second is a new novel dual reflector Gregorian antenna system designed to meet the stringent requirements of the newly proposed CubeSat satellite paradigm by folding the optics into one of the most compact dual reflectors to date. The design combines a high gain reflectarray main aperture with an ellipsoidal subreflector fed by a patch array feed. The system is coplanar with the CubeSat chassis, deploying only the subreflector and thus has no moving cables or RF parts. This antenna design also requires a complex computer code to design. The code implemented to design the reflectarrays applies several novel acceleration strategies to the spectral domain method of moments algorithm in order to speed up the calculations. The theory and mathematical formulations behind this algorithm are also presented, as well as the resultant designs and measurements. The accelerated codes are used to design several Ka-Band reflectarrays. Measured and simulated results are provided.

This book was released on 2016-11-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-based observations have transformed our understanding of Earth, its environment, the solar system and the universe at large. During past decades, driven by increasingly advanced science questions, space observatories have become more sophisticated and more complex, with costs often growing to billions of dollars. Although these kinds of ever-more-sophisticated missions will continue into the future, small satellites, ranging in mass between 500 kg to 0.1 kg, are gaining momentum as an additional means to address targeted science questions in a rapid, and possibly more affordable, manner. Within the category of small satellites, CubeSats have emerged as a space-platform defined in terms of (10 cm x 10 cm x 10 cm)- sized cubic units of approximately 1.3 kg each called "U's." Historically, CubeSats were developed as training projects to expose students to the challenges of real-world engineering practices and system design. Yet, their use has rapidly spread within academia, industry, and government agencies both nationally and internationally. In particular, CubeSats have caught the attention of parts of the U.S. space science community, which sees this platform, despite its inherent constraints, as a way to affordably access space and perform unique measurements of scientific value. The first science results from such CubeSats have only recently become available; however, questions remain regarding the scientific potential and technological promise of CubeSats in the future. Achieving Science with CubeSats reviews the current state of the scientific potential and technological promise of CubeSats. This report focuses on the platform's promise to obtain high- priority science data, as defined in recent decadal surveys in astronomy and astrophysics, Earth science and applications from space, planetary science, and solar and space physics (heliophysics); the science priorities identified in the 2014 NASA Science Plan; and the potential for CubeSats to advance biology and microgravity research. It provides a list of sample science goals for CubeSats, many of which address targeted science, often in coordination with other spacecraft, or use "sacrificial," or high-risk, orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms deploying tens to hundreds of CubeSats that function as one distributed array of measurements.

Book Synopsis Contributions to the advance of the integration density of CubeSats by : Grau, Sebastian
Download or read book Contributions to the advance of the integration density of CubeSats written by Grau, Sebastian and published by Universitätsverlag der TU Berlin. This book was released on 2019-09-17 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates potential technologies to increase the integration density of CubeSats. Observations of the CubeSat market and missions are recorded in order to derive design criteria for high performance single unit CubeSats. A promising approach to increased integration density is relocation of the components of multiple satellite subsystems to form a highly integrated, multi-functional solar panel. Eligible components are usually allocated to the communication system, the electric power system, or the attitude determination and control system. In a joint research project, development, optimization, and miniaturization of those components in order to form a highly integrated, multi-functional solar panel is investigated. The author first summarizes the development work of the project partners for a picosatellite solar antenna and puts it into relation to the overall solar panel design. Advantage of using solar antennas over simple patch antennas is the reduced loss of solar cell area, and hence available electric power, that is usually accompanied by the usage of higher frequency bands for broadband payload data transmission. Magnetic attitude actuators are the backbone of CubeSat attitude control. In order to increase their performance and lower their resource consumption, numerical optimization of the commonly used three coil types is investigated by the author. This leads to the formulation of a novel optimization approach, which is better suited to real-world considerations for magnetic actuator design. Results from the application of the optimization procedure show potential for every coil type. The state of the art of a novel type of attitude control actuators, so-called fluid-dynamic actuators which are based on angular momentum exchange, is advanced by the author by introducing miniaturized 3D-printed conduits for single unit CubeSat applications. Following development and functional verification, actuators are compared to existing reaction wheel systems, which shows their superiority for agile attitude maneuvers and integration with the satellite bus. Further investigation exploits additive manufacturing technologies to create redundancy concepts using four actuators with three-dimensional conduits.Finally, development, optimization, and miniaturization of subsystem components is brought together in the design, assembly, and test of a highly integrated, multi-functional solar panel. Analysis of a single unit CubeSat design that applies different configurations of the multi-functional solar panel shows the potential for more than 50% payload mass and payload volume. This brings integration density of single unit CubeSats to a level similar to that of the larger triple unit form factors currently employed for the New Space mega-constellations. Diese Dissertation untersucht mögliche Technologien zur Erhöhung der Integrationsdichte von CubeSats. Beobachtungen des CubeSat-Marktes und ausgewählter Missionen werden zusammengetragen um Entwurfskriterien für hochperformante 1U CubeSats abzuleiten. Ein vielversprechender Ansatz zur Erhöhung der Integrationsdichte ist der Umzug von Komponenten verschiedener Satellitensubsysteme auf ein zu entwickelndes hochintegriertes, multifunktionales Solarpaneel. Infrage kommende Komponenten sind für gewöhnlich dem Kommunikationssystem, dem Energieversorgungssystem, oder dem Lageregelungssystem zugeordnet. In Rahmen eines gemeinschaftlichen Forschungsvorhabens wurden Entwicklung, Optimierung, und Miniaturisierung ausgewählter Komponenten eines solchen hochintegrierten, multifunktionalen Paneels untersucht. Durch den Autor wird zunächst die Entwicklung einer Solarantenne für Pikosatelliten durch den Projektpartner zusammengefasst und in Zusammenhang um Entwurf des Solarpaneels gebracht. Der Vorteil einer Solarantenne gegenüber einer einfachen Patch-Antenne ist der geringere Verlust an Solarzellenfläche, und damit zur Verfügung stehender elektrischer Leistung, der üblicherweise mit der Verwendung höherer Frequenzbänder zur breitbandigen Nutzlastdatenübertragung einhergeht. Magnetische Lageregelungsaktuatoren bilden das Rückgrat der CubeSat-Lageregelung. Um deren Leistungsfähigkeit zu erhöhen und den Ressourcenverbrauch zu verringern, wird durch den Autor die numerische Optimierung der drei gebräuchlichen Spulentypen untersucht. Dies führt zur Formulierung eines neuartigen Optimierungsansatzes welcher besser für die Anwendung realer Entwurfsprobleme geeignet ist. Die Optimierungsergebnisse zeigen ein großes Potential für die Optimierung aller betrachteter Spulentypen auf. Der Stand der Technik im Bereich neuartiger Lageregelungsaktuatoren, den sogenannten fluiddynamischen Aktuatoren die auf Drehimpulsaustausch basieren, wird durch den Autor durch die Einführung miniaturisierter 3D-gedruckter Kanäle für die Verwendung auf 1U CubeSats vorangebracht. Im Anschluss an die Entwicklung und funktionale Verifikation werden diese Aktuatoren mit existierenden Reaktionsradsystemen verglichen, was deren Überlegenheit bei agilen Lageregelungsmanövern und der Integration in den Satellitenbus aufzeigt. Weitere Untersuchungen nutzen die additiven Herstellungsverfahren zur Darstellung von redundanten Konzepten bestehend aus vier Aktuatoren mit dreidimensionalen Kanalgeometrien. Abschließend werden Entwicklung, Optimierung und Miniaturisierung der Subsystemkomponenten im Entwurf, Aufbau und Test eines hochintegrierten, multifunktionalen Seitenwandpaneels zusammengeführt. Die Analyse eines 1U CubeSat-Entwurfs unter Verwendung verschiedener Konfigurationen des multifunktionalen Solarpaneels zeigt ein Potential für jeweils mehr als 50% verfügbarer Nutzlastmasse und Nutzlastvolumen vom gesamten Satelliten. Dies hebt die Integrationsdichte von 1U CubeSats auf ein ähnliches Niveau der 3U Formfaktoren, welche gegenwärtig bei den New Space Megakonstellationen zur Anwendung kommen.

Download or read book Attitude Stabilization for CubeSat written by Mohammed Chessab Mahdi and published by Cambridge Scholars Publishing. This book was released on 2018-11-14 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores CubeSat technology, and develops a nonlinear mathematical model of a spacecraft with the assumption that the satellite is a rigid body. It places emphasis on the CubeSat subsystem, orbit dynamics and perturbations, the satellite attitude dynamic and modeling, and components of attitude determination and the control subsystem. The book focuses on the attitude stabilization methods of spacecraft, and presents gravity gradient stabilization, aerodynamic stabilization, and permanent magnets stabilization as passive stabilization methods, and spin stabilization and three axis stabilization as active stabilization methods. It also discusses the need to develop a control system design, and describes the design of three controller configurations, namely the Proportional–Integral–Derivative Controller (PID), the Linear Quadratic Regulator (LQR), and the Fuzzy Logic Controller (FLC) and how they can be used to design the attitude control of CubeSat three-axis stabilization. Furthermore, it presents the design of a suitable attitude stabilization system by combining gravity gradient stabilization with magnetic torquing, and the design of magnetic coils which can be added in order to improve the accuracy of attitude stabilization. The book then investigates, simulates, and compares possible controller configurations that can be used to control the currents of magnetic coils when magnetic coils behave as the actuator of the system.
