Dynamics and Aerodynamic Control of a Cross-Track Tether Satellite System
Authors:   Politecnico Di Torino, Torino, Italy, Aliberti Stefano , B. Quadrelli Marco , Romano Marcello
Published: January 2024

The objective of this paper is to present and analyze the dynamics and control strategy of a novel type of formation flight architecture, that could enable unprecedented space mission capabilities. In particular we propose and study a tether satellite system composed by two or more satellites, flying in LEO, connected by a linear tether. That tether is maintained in tension along the cross-track direction, with respect to the orbit, i.e., perpendicular to the motion and radial directions, by exploiting the aerodynamic lift acting upon the suitably oriented satellites.

Possible applications of this formation are related, in particular, to remote sensing.

To carry out the study, a three-dimensional multibody model was developed, introducing the equations of relative dynamics centered in an orbiting reference frame.

To simulate the conditions of low Earth orbit, several mathematical models taken from the literature were used, in order to include the Earth’s gravitational potential up to fourth order, solar pressure, third-body perturbations, atmospheric drag and the behavior of aerodynamic surfaces in a free molecular flow.

By utilizing this model and verifying that this configuration is intrinsically unstable, it was concluded that the system needs continuous control to be stabilized.

As a result, the model of the dynamics was linearized and an optimal LQR controller was introduced to calculate the force required to hold the system in place. Once the linear control law was validated by simulating its application on the full system model, aerodynamic surfaces were next introduced in order to generate the force required for control by taking advantage of the rarefied atmosphere of low Earth orbit.

The proposed control strategy is tested by extensive numerical simulations.

Finally, the proposed aerodynamic stabilization approach to continuously maintain a linear tether satellite system along the cross-track direction was compared to a gyroscopic stabilization alternative strategy.

This strategy consists of putting the system into rotation in a direction perpendicular to the cross-track direction. The centrifugal force generated by the rotation stabilizes the system, maintaining constant oscillations in the cross-track direction throughout the orbit.

Both cases have been analyzed as the size of the system and the number of satellites change.

Published: January 2024

The Geostationary Operational Environmental Satellite-R program (GOES-R) has launched three of the latest generation of US geostationary weather satellites, of which all three are now fully operational. In this paper we discuss how the robust capabilities inherent in the design have been used to address off-nominal instrument performance observed in flight, and to subsequently provide acceptable data return from two of the instruments exhibiting off-nominal performance. The primary science instrument, the Advanced Baseline Imager (ABI), performed well on GOES-16, but on GOES-17 ABI exhibited anomalous infrared (IR) imaging early in the mission. Lower thermal control performance than designed produced elevated temperatures on the IR detectors. This paper presents spacecraft operations undertaken to calibrate the off-nominal performance of the instrument thermal control, and to develop spacecraft operational mitigation steps to recover near-nominal instrument performance. On GOES-16, the magnetometer (MAG) instrument performance was less than expected. As part of the MAG performance investigation, an improved calibration procedure was developed that required use of the entire GOES-R performance envelope. This paper presents an overview of the MAG performance issues and discusses details of the Guidance, Navigation, and Control capabilities employed to help maximize science return.
ARIETIS and ARIETIS-NS gyros test results and qualification status
Authors:   Innalabs Ltd, Blanchardstown, Ireland, Torasso Alberto , Diram Romain , Heffernan Alan , Kowaltschek Steeve
Published: January 2024

ARIETIS and ARIETIS-NS are two gyroscopes for space applications developed by Innalabs based on its proprietary CVG technology. ARIETIS is an ITAR free, Rad-Hard 3-axis gyroscope whose main applications are Earth Observation, Science missions, Telecom, as well as Navigation, Earth Observation, as well as Science missions. It uses class 1 EEE components and meets ESA ECSS standards. ARIETIS-NS is an ITAR free, rad and Single Event Effects (SEEs) tolerant 3-axis gyroscope. It is developed following ECSS standard with the exception of using commercial EEE components that are upscreened by means of radiation testing. ARIETIS-NS is intended for commercial satellites (both LEO and GEO), constellations and mega-constellations, but it has also been selected for science and exploration missions.

ARIETIS and ARIETIS-NS are both based on InnaLabs proprietary Coriolis Vibratory Gyroscope (CVG) technology which is currently used in Space on board both LEO and GEO applications. InnaLabs CVG gyros have already cumulated more than 3,000,000 hours in flight with no failures and no deviation from the specified performance, confirming the suitability of the technology to space environment.

After a brief description of the InnaLabs CVG basic principles and an overview of the CVG technical strengths in comparison to competing technologies, this paper describes the specification. key design features, and budgets of both ARIETIS and ARIETIS-NS. Both gyros are able to provide high performance (ARW <0.005 deg/√hr) and high reliability (~1000 FITs) in a very compact design (~1.2 kg for ARIETIS-NS and ~3kg for ARIETIS) and very low power consumption (<6W). To achieve this, several targeted enhancements and optimisations to InnaLabs gyroscope's design have been introduced, mainly in the component selection, the control loops, the compensation algorithms, and a smaller Sensing Element design.

ARIETIS-NS has recently completed qualification where multiple qualification models were used to characterize different configurations of the product. Qualification test results will be presented to show the gyro compliance to the specification in terms of performance and compatibility to both mechanical and thermal environment. ARIETIS is at the start of the qualification campaign with the qualification model currently under MAIT. Several ARIETIS engineering models have been built and tested and test results are presented in the paper.
Fast Sequential Convex Programming with Relaxed Convergence Criteria
Authors:   Airbus Defence & Space, Stevenage, United Kingdom, Popov Alexander , Contini Cristiano , Zamaro Mattia
Published: January 2024

The growing interest in lunar exploration demands the development of spacecraft which can land autonomously on the Moon’s surface. Typically, such missions define an ellipse around some selected landing point and any location within this ellipse is deemed acceptable for touchdown. To ensure a safe landing, a spacecraft can employ a hazard detection and avoidance (HDA) system, capable of identifying potential dangers at the target and triggering diversion to another point within the ellipse. The choice of landing site for a mission is a compromise between scientific priorities and landing safety. However, many scientific sites of interest may not be well-suited to landers as there may be hazards, such as craters or rocks, which greatly limit the size of a potential landing ellipse. To enable a broader range of missions, a lander should be capable of diverting to a new target at relatively low altitude and efficiently reaching the target with pinpoint accuracy. This would not only make it possible to reduce the minimum landing ellipse size for a given vehicle design, but it would also allow for a relaxation of the surface hazard requirements within the chosen ellipse. If this can be achieved, then a much more versatile set of lunar landing sites can be considered, prioritising scientific needs over engineering limitations.

Fast and accurate retargeting demands a sophisticated guidance algorithm which can rapidly compute a trajectory to a new point. This paper presents progress on such an algorithm, which solves a trajectory optimisation problem to achieve fuel-optimal pinpoint landing. To enable late diversion, this algorithm must be able to run on board the spacecraft in real time, and so our research has focused on the use of fast, resource-efficient methods based on sequential convex programming.

We recommend two related strategies which can enable fast termination of sequential convex programming algorithms: Hermite interpolation to extract a continuous-time state trajectory from the convex solver, and mesh refinement to enable efficient convergence towards an accurate solution. In combination, these techniques can ensure that the algorithm terminates after only a few iterations, using relatively relaxed stopping criteria, while still producing a feasible solution which can exactly satisfy terminal equality constraints. The benefits of this framework are demonstrated using the case study of guidance for an autonomous lunar lander with a complete model of the system dynamics in six degrees of freedom.
RVS®3000 LIDAR Product Family from Rendezvous and Docking Applications to Hazard Mapping for Planetary Landing
Authors:   Jena-Optronik GmbH, Jena, Germany, Kämpfe Thomas , Schmitt Christoph , Windmüller Michael , Schwarz Michael , Möller Max
Published: January 2024

The RVS®3000 LIDAR product family is regularly used for retro tracking during flights to the international space station since 2019. A version for operation without retro reflectors used powerful algorithms and hardware for autonomous 6-Degree-of-Freedom (6DOF) pose estimation to enable satellite-servicing during Northrop Grumman’s (NG) Mission Extension Vehicle (MEV) program. For the Artemis Missions, the RVS®3000 LIDAR product family shall serve as primary relative navigation sensor on the ORION vehicle. The combination of high-resolution scanning LIDAR with robust image processing algorithms shall enable rendezvous and docking with e.g. Gateway.

Here we present the generic LIDAR system design as it was developed by Jena-Optronik GmbH for a variety of missions. This design will be introduced by the example of a rendezvous vehicles. Here we start from tracking of available retro reflectors from several kilometres down to autonomous 6-Degree-of-Freedom (6DOF) pose estimation with the docking port at close range. The algorithms exploit the full capability of the hardware by making use of “the best from the two worlds” of retro reflector tracking and model-based 6DOF pose estimation. This presentation will summarize simulation and test results.
Spherical Air-bearing AOCS testbed with parasitic moments of inertia cancelation
Authors:   Huld, Espoo, Finland, Jovanovic Nemanja , Praks Jaan
Published: January 2024

A spherical air-bearing AOCS testbed, equipped with an external torque generating subsystem, is proposed. Such a system could enhance satellite hardware testing, verification, and validation capabilities of typical air-bearing testbeds. The externally generated torque can be used for simulating environmental disturbance torques, but more importantly it can actively modify and correct the dynamical response of the system under test (SUT). This allows for correction of the SUT’s experienced moments of inertia (MOI), or its continuous alteration to simulate complex mechanical processes, such as panel deployment or tether dynamics. This study is focused on the cancellation of the parasitic MOI, which originate from the testbed’s spherical enclosure. Capability to remove the parasitic MOI would allow building testbeds for use with flight ready nanosatellites that would provide them with nearly realistic dynamics experience, enabling end-to-end validation testing of attitude maneuver scenarios. The air-bearing testbed is modeled in a numerical simulator. The simulation is used for the development of the control algorithms for the parasitic MOI cancellation using external torque generating subsystem. Performance of the testbed and algorithms is characterized and presented.
LAUNCH VEHICLE STIFFNESS BUDGET SENSITIVITY TO CONTROL STABILITY CONSTRAINTS
Authors:   Avio S.p.a., Colleferro, Italy, Patrizia Cotugno Miss , Aveta Mirko , Leto Giuseppe , Lopez Alessandro , Curti Gianluca
Published: January 2024

In the design phase of a new launch vehicle, the stiffness budget analysis represents an essential task. Indeed, during its flight, the launcher is subject to significant external forces which may lead to instability. As a consequence, the stiffness of each item of the launch vehicle has a fundamental impact on the definition of the global bending modes’ parameters and on the fulfilment of the launch vehicle control stability requirements. In this context, this article focuses on a sensitivity analysis to the stiffness budget robustness, obtained by varying each item’s stiffness and computing the launch vehicle worst-case stability margins.

The VEGA-E (Evolution) launcher has been considered as a benchmark for the activity under study. Indeed, this launcher is currently in the second development phase and lends itself well to this type of analyses that could lead to improvements in its design.

The analysis proposed in this paper allows to graphically assess which parameters mostly affect the fundamental bending modes’ eigenfrequencies and shapes and to approximate the impact of stiffness budget changes in terms of launch vehicle performance in view of mass saving optimizations.

A set of stiffness budget alternates has been considered and an uncertain Linear Fractional Representation (LFR) of the launch vehicle has been defined for each different design case. It is worth to underline that, since the slosh masses are not deterministically known by the Finite Element Model (FEM), the bending modes have been computed considering three different values slosh masses (minimum, nominal and maximum). Moreover, considering that the payload mass represents another factor that adds variability to the bending modes’ parameters, two different payload configurations (minimum and maximum) have been considered in the FEM model.

With this set-up, the structural stiffness needs have been verified with respect to the control related requirements by examining all the considered data sets from the stability point of view. Since the stiffness variations mostly affect the bending modes, for each case taken under study a tuning of the bending filter has been performed using the structured H∞ technique.

To fasten up computations, it has been assumed that the worst-case tuning condition is to be the least controllable design point according to the aerodynamic to thrust efficiency ratio.

Results have shown that this strategy makes it possible to ease the controllability constraint in the stiffness budget optimization, allowing a possible improvement in terms of performance and guaranteeing at the same time the fulfilment of the required worst-case stability margins.

Authors:   Astro- Und Feinwerktechnik Adlershof GmbH, Berlin, Germany, Mayer Alexander , Hafemeister Lisa , Bretfeld Roy , Raschke Christian , Jahn Heiko
Published: January 2024

Nowadays, primarily conventional reaction wheels are used to control the attitude of spacecrafts. Nevertheless, some missions require the attitude control to be much more agile. Due to their functional principle Control Moment Gyroscope (CMG) based control systems provide a much higher agility and are thus getting more and more important.

Astro- und Feinwerktechnik Adlershof GmbH (Astrofein) is currently developing a CMG for Small Satellites supported by ESA GSTP-6. To make CMGs available for smaller satellites, a trade-off between volume and mass as well as power consumption and performance had to be made. The current design ensures a high target performance of 8Nms/14Nm with a dedicated mass of 8kg and a maximum power consumption of about 40W. An Engineering Qualification Model (EQM) was built and is currently undergoing an environmental test campaign, that includes different tests such as the Thermal-Vacuum and Micro Vibration test. The specification and the current status of the CMG as well as an insight on the test results with regards to the performance of the CMG within the environmental tests will be given in this paper.
Mini-Spacestar: a successful product updated to adapt to the needs of new space markets
Authors:   Leonardo, Campi Bisenzio (Florence), Italy, Boldrini Franco , Bettarini Rossano , Procopio Dorico , Berrighi Gianni
Published: January 2024

The Leonardo SPACESTAR product is going to be updated with the main goal of reducing size and mass (Mini Spacestar) while maintaining the same performance and flight heritage of a well consolidated product, with hundreds of units flying since many years.

The Mini Spacestar updated electronics will be even more compact than before and still dedicated to APS control and image pre-processing, while a SW (delivered by Leonardo) embedded in the central AOCS computer will calculate the quaternions. As a result, the Mini Spacestar confirms the same architectural configuration of SPACESTAR, which already demonstrated to provide a significant reduction of recurring costs at AOCS level thanks to CPU resources sharing.

The Mini Spacestar electrical I/F and data I/O will remain unchanged with respect to the predecessor, to allow replacing at zero cost in the platforms that already adopted this product.

The Mini Spacestar will be available either with components fully space qualified (for missions with high reliability requirements), or in a configuration based on “New Space” components. The “NS” Mini Spacestar will provide adequate quality and resistance to radiations through components efficiently selected or locally shielded, at the same time allowing a significant reduction of recurring costs and meeting the requirements of the “New Space” Missions.

Finally, thanks to its high performance and reduced dimensions, the Mini Spacestar is suitable to be integrated directly on the optical bench of observation payloads (e.g. Optical payloads) to increase System pointing (and geolocation) performances, where required. Studies are in progress at Leonardo and some highlights will be given as part of the paper.

Development of highly adaptive reaction wheels for geostationary and high agility satellites
Authors:   Astro- und Feinwerktechnik Adlershof GmbH, Berlin, Germany, Bartels Friedrich , Raschke Christian , Desplats Eric
Published: January 2024

The RW6000 is the first wheel of Astrofein's newly developed family of smart high-momentum reaction wheels that has been fully qualified. The 100 Nms wheel makes use of Astrofein's heritage wheel technologies like the flexible structure concept and smart functions as closed-loop speed and torque control. As all of Astrofein's reaction wheels it is open to the environment (not hermitically sealed).

Even if, the wheel is based on exiistng heritage, Astrofein faced several challenges during the development. This included challenges related to qualifying new technologies like the lead-free assembly process for the wheel drive electronics and the identification and qualification of automotive grade EEE parts. But, also scaling effects related to the wheel size were underestimated, like air drag effects during ground testing. Other challenges were mission related. One of these mission related challenges was the development of a critical SW for driving and controlling the wheel.

The paper will provide some details on the challenges faced during the development and how they have been solved. Furthermore, it gives details of the key performance parameters of the wheel and the performed qualifications. Finally, it will give an outlook what possible further improvements are planned and how the achievements will be utilized for other wheels in Astrofein's family of high-momentum reaction wheels.

Published: January 2024

While the role and benefit of perioperative intravenous (IV) antibiotics in patients undergoing total joint arthroplasty (TJA) is well-established, oral antibiotic use in TJA remains a controversial topic with wide variations in practice patterns. With this review, we aimed to better educate the orthopedic surgeon on when and how oral antibiotics may be used most effectively in TJA patients, and to identify gaps in the literature that could be clarified with targeted research.

Extended oral antibiotic prophylaxis (EOAP) use in high-risk primary, aseptic revision, and exchange TJA for infection may be useful in decreasing periprosthetic joint infection (PJI) rates. When prescribing oral antibiotics either as EOAP or for draining wounds, patient factors, type of surgery, and type of infectious organisms should be considered in order to optimally prevent and treat PJI. It is important to maintain antibiotic stewardship by administering the proper duration, dose, and type of antibiotics and by consulting infectious disease when necessary.

The results obtained make it possible to determine muscle local exhaustion and take appropriate measures (change the training regime, prescribe appropriate recovery procedures, etc.), which helps to avoid an ineffective training course.The information content of myotonometry increases with dynamic observations. Special attention should be paid to the description of individual indicators of the muscle tone amplitude as an integrative indicator of the functional state of basketball players neuromuscular system.
“The war depends on you”: Suicidal Romanticism in Jeff Buckley’s Grace
Authors: McConville James
Published: January 2024

In recent decades, scholars including Jerome McGann and Anne K. Mellor have interrogated the previously stable borders of various moments of literary criticism and philosophy, including Romanticism and its consideration of conflict, unity, and identity. Such interrogation has resituated texts not traditionally associated with the Romantic period in new theoretical lights. Surveying landscapes of contemporary sensibilities of masculinity, this article will argue that the central figures in Jeff Buckley’s Grace represent a trope in Romantic texts the author has developed from Nicholas Saul’s exploration of “Romantic suicide.” Suicidal Romanticism encapsulates Buckley’s subject in its search for an authentic and unique identity and eventual disavowal of identity altogether. McGann’s widening of the Romantic landscape provides credence for broader swaths of connection between cultural periods, literary criticisms, and textual forms, situating artists like Buckley within the bounds of a Romanticism engrossed in the examination of conflicted personalities searching for meaning and wholeness.
What Timaeus Can Teach Us: The Importance of Plato’s Timaeus in the 21st Century
Authors:   Department of Philosophy, Alma College, Campbell Douglas R.
Published: January 2024

In this paper, I make the case for the continuing relevance of Plato’s Timaeus. I begin by sketching Allan Bloom’s picture of the natural sciences today in The Closing of the American Mind: How Higher Education Has Failed Democracy and Impoverished the Souls of Today’s Students (1987), according to which the natural sciences have, objectionably, become increasingly specialized and have ejected humans qua humans from their purview. I argue that Plato’s Timaeus, despite the falsity of virtually all of its scientific claims, provides a model for how we can pursue scientific questions in a comprehensive way that stresses their connections to other disciplines, including the humanities, and that puts humanity qua humanity back in the picture. I then argue that being led by Plato’s philosophy to return humanity conceptually to the natural world can improve our thinking regarding climate change and other important environmental crises.
Platono Teaiteto digresija šiandien, arba Sokrato laiškas nūdienos filosofams

This paper discusses the relevance of ancient thought by briefly reviewing the historical reception vicissitudes of Plato’s dialogue Theaetetus, and by considering what dialogue’s themes and motifs seem pertinent to contemporary thinkers. As in earlier times, Socrates’ critique of relativism and subjectivism, the problems of the justification of knowledge, as well as the holistic conception of knowledge remain undoubtedly valuable in the dialogue. In recent decades, research on the pedagogical motives of dialogue has also increased. Finally, it seems that never before have the protagonist’s proud words about scholē – the free, quiet time of thinking, unaffected by political urgency and conjuncture, as an essential condition for philosophical activity and life – sounded so insightful. This is what I call “Socrates’ Letter to Contemporary Philosophers”.
Leo Strausso sugrįžimas prie užmiršto rašymo meno
Authors:   Lithuanian Culture Research Institute, Jokubaitis Linas
Published: January 2024

The aim of this article is to reconstruct Leo Strauss’ project of a return to the forgotten art of writing and to demonstrate its relation to his attempts to find alternatives to historicist positions. By emphasizing the insoluble conflict between the political community and philosophical life medieval philosophers opened up the possibility of a novel understanding of the premodern philosophical tradition. This new perspective is based on the assumption that philosophers of the past attempted to avoid persecution and wanted to protect their societies from the potentially destructive effects of philosophical radicalism, which is why the presentation of their doctrines was formed by the distinction between esoteric and exoteric doctrines. The forgetfulness of the technique of careful writing began with the implementation of liberal political principles and was furthered by the triumph of historicist assumptions. Strauss’ return to classical political philosophy is inseparable from his polemics with historicist positions that negate the fundamental assumptions of this tradition. By emphasizing the distinction between esoteric and exoteric elements of philosophical texts Strauss introduces a technique of interpretation which is based on attempts to distinguish between elements that have a transhistorical meaning and are found in the esoteric doctrine, from the exoteric teaching, which has always been accommodated to the dogmas and prejudices of concrete society. The attempt to reconstruct the transhistorical elements of doctrines is inseparable from the goal of returning to the natural consciousness that is to be found in the tradition of ancient political philosophy.

Según la Organización Mundial de la Salud (OMS), el estrés laboral es una reacción que puede manifestarse ante exigencias y presiones laborales que ponen a prueba la capacidad que tiene cada persona para afrontar ciertas situaciones y que se agravan en el personal de salud que atiende pacientes con la COVID-19. Es decir, lo que resulta del desequilibrio entre las presiones y exigencias a las que se enfrenta el individuo, por una parte, y los conocimientos adquiridos, por otra parte. El Síndrome de desgaste profesional, conocido también como síndrome de agotamiento emocional o psicológico, o por el anglicismo burnout, es un tipo de estrés laboral que engloba un estado de agotamiento físico, emocional y mental que conlleva consecuencias individuales y sociales. El objetivo de esta revisión narrativa es identificar los factores de riesgo para el desarrollo del Síndrome de desgaste profesional en el personal de salud relacionado con la atención de pacientes con la COVID-19. Se realizó una búsqueda en la base de datos PubMed, se incluyeron artículos originales, estudios aleatorizados, revisiones sistemáticas y otros textos en español e inglés, publicados durante el periodo 2020-2023. Los principales factores de riesgo identificados en la literatura para el desarrollo de Síndrome de desgaste profesional fueron la juventud, sexo femenino, la soltería, la carga de trabajo y el nivel de satisfacción laboral de los profesionales.
