The transition to the leaky design of the instrument compartment of the spacecraft inevitably leads to additional thermal loads on the components of the onboard electronic equipment due to a change in the heat transfer scheme. The thermal mode of operation of the onboard radio-electronic equipment of the spacecraft is one of the important factors for ensuring the long term active existence of the spacecraft. Ensuring the long term of active existence of spacecraft is the most important scientific, engineering and economic task, the solution of which requires a deep systematic approach at all stages of the creation and operation of onboard electronic equipment of the spacecraft. The strategic objective for ensuring the long term of the spacecraft’s active existence is the implementation at all stages of the life cycle of onboard radio-electronic equipment of the highest achievable reliability indicators through the using of modern design and technological solutions, as well as effective methods for its design and production. This article presents the results of experimental work to reduce heat transfer resistance between onboard electronic equipment and the spacecraft’s thermal control system. As a result of the work, the main data were obtained on improving the heat sink efficiency of the energy-converting equipment of the spacecraft, the effectiveness of measures to ensure heat removal of the onboard radio-electronic equipment of the spacecraft was confirmed.

Nowadays rocket and space industry enterprises use a simplified method to evaluate failure and fault tolerance of the onboard equipment to single event effects (SEEs), when the calculation is performed for the minimum mass protection thickness (g/cm2 ) of potentially sensitive electronic components determined, as a rule, by the minimum wall thickness of the device under consideration. In this case, all structural elements of the onboard equipment, spacecraft, and neighboring devices are not included, which, in many cases, leads to a significant overestimation of the calculated SEEs frequency especially for large scale integration ICs. Neglecting the actual mass protection may require redundant measures to ensure failure and fault tolerance. The work proposes an improved approach of calculating failure and fault tolerance of sensitive electronic components and onboard equipment to the impact of heavy charged particles and high-energy protons that causes SEEs, which consists in using programs for calculating absorbed doses by the sectorization method in three-dimensional models, which makes possible to determine the minimum, maximum, and average mass protection of electronic components with the complete design of the onboard equipment and spacecraft.

The ground-experimental testing of the elements of space technology is a crucial stage in the creation of space products, in fact, this is the ground «flight» of the devices being created. And how well the operating conditions will be reproduced at this stage and the successful functioning of the devices under the expected conditions is ensured, its successful operation in real flight during the service life depends. The radio electronic devices of the onboard equipment of the spacecraft are one of the essential elements that ensure the fulfillment of target tasks, which should confirm their readiness for the forthcoming work at the stage of groundbased experimental testing. The article discusses the stages of information support for the development of spacecraft onboard equipment, showing the ways to improve the technology of ground-based experimental testing of spacecraft onboard equipment. It is shown that at the present stage of development of the space industry, it has become possible to introduce the methodology of mathematical planning of an experiment into engineering practice. A backlog of applied work on radio-electronic topics h as appeared, showing the possibility of revealing in a full factorial experiment the influence of internal uncontrollable parameters (factors) of electronic components on the experimental results. This removed the obstacle to the implementation of the capabilities of the method in research and improvement of radio electronic devices onboard equipment.

Rail transit is developing towards intelligence which takes lots of computation resource to perform deep learning tasks. Among these tasks, object detection is the most widely used, like track obstacle detection, catenary wear, and defect detection and looseness detection of train wheel bolts. But the limited computation capability of the train onboard equipment prevents running deep and complex detection networks. The limited computation capability of the train onboard equipment prevents conducting complex deep learning tasks. Cloud computing is widely utilized to make up for the insufficient onboard computation capability. However, the traditional cloud computing architecture will bring in uncertain heavy traffic load and cause high transmission delay, which makes it fail to complete real-time computing intensive tasks. As an extension of cloud computing, edge computing (EC) can reduce the pressure of cloud nodes by offloading workloads to edge nodes. In this paper, we propose an edge computing-based method. The onboard equipment on a fast-moving train is responsible for acquiring real-time images and completing a small part of the inference task. Edge computing is used to help execute the object detection algorithm on the trackside and carry most of the computing power. YOLOv3 is selected as the object detection model, since it can balance between the real-time and accurate performance on object detection compared with two-stage models. To save onboard equipment computation resources and realize the edge-train cooperative interface, we propose a model segmentation method based on the existing YOLOv3 model. We implement the cooperative inference scheme in real experiments and find that the proposed EC-based object detection method can accomplish real-time object detection tasks with little onboard computation resources.

Problem statement. In recent years, the problem of replacing copper-core fiber-optic cables has become particularly relevant. This is due to two factors: first, the prospect of introducing unmanned vehicles and the development of electromagnetic microwave weapons that can disable electronic equipment for almost any target at a distance of 10 km or more, and second, the growing need to reduce the delay of transmitted signals on the network and increase the volume of information transmitted in these networks. The article describes the construction of onboard cable networks using fiberoptic cables. The advantages and disadvantages of fiber-optic based onboard networks are described.Objective.

It is shown that the joint use of radio frequency range onboard equipment radio systems near navigation (RSBN) and LTE networks requires both organizational and technical measures, and the implementation of measures of conversion of the radio frequency spectrum on a local‑territorial principle. Attention is drawn to the need for the improvement of on‑Board equipment of the RSBN with modes of short‑range and inter‑flight navigation, taking into account the needs of users of the national frequency resource. It is noted that the cardinal solution to the problem of conversion of the considered frequency band is the transfer of on‑Board equipment of the RSBN from the domestic frequency range occupied by the LTE communication network to the international frequency range of the air radio navigation service 960–1215 MHz. The solution of the problem of joint use of the frequency band 791–821 MHz by the onboard equipment of radio engineering systems of short‑range navigation and radio electronic means of LTE networks for the transition period until the conversion is completed is possible by reducing the frequency resource (channels) for the on‑Board equipment of RSBN with the modes of short‑range and inter‑flight navigation or redistribution of the frequency resource initially nominated for the competition for radio electronic means of the LTE‑800 standard.

Over the past decade, the satellite industry has witnessed the birth and evolution of the CubeSat standard, not only as a technology demonstrator tool but also as a human capacity development platform in universities. The use of commercial off the shelf (COTS) hardware components makes the CubeSat a cost effective and ideal solution to gain access to space in terms of budget and integration time for experimental science payloads. Satellite operations are autonomous and are essentially based on the interaction of interconnected electronic subsystems exchanging data according to the mission requirements and objectives. The onboard computer (OBC) subsystem is developed around a microcontroller and plays an essential role in this exchange process as it performs all the computing tasks and organises the collection of onboard housekeeping and payload data before downlink during an overpass above the ground station. The thesis here presented describes the process involved in the development, design and implementation of a prototype OBC for a CubeSat. An investigation covering previously developed CubeSat OBCs is conducted with emphasis on the characteristics and features of the microcontroller to be used in the design and implementation phases. A set of hardware requirements are defined and according to the current evolution on the microcontroller market, preference is given to the 32-bit core architecture over both its 8-bit and 16-bit counterparts. Following a well defined selection process, Atmel’s AT91SAM3U4E microcontroller which implements a 32-bit Cortex-M3 core is chosen and an OBC architecture is developed around it. Further, the proposed architecture is implemented as a prototype on a printed circuit board (PCB), presenting a set of peripherals necessary for the operation of the OBC. Finally, a series of tests successfully conducted on some of the peripherals are used to evaluate the proposed architecture.

La protection du matériel électronique embarqué est devenue un enjeu majeur pour assurer la sécurité du combattant. On peut citer divers exemples tels que la protection des piles à hydrogène dans les véhicules ou dans la batterie embarquée d'un soldat. C'est dans ce contexte que s'inscrit la thèse, où une étude est menée sur une protection de type multi-couches, sollicitée par des projectiles de type fragment, de quelques kilogrammes, allant à des vitesses de l'ordre de 10 m/s. Afin d'assurer la mise en service de telles protections, des essais et des simulations doivent être menés sur un large champ de sollicitations. La littérature montre que les structures multi-couches offrent un bon compromis entre capacité à absorber l’énergie d’impact et légèreté. Le complexe étudié pour cette thèse est composé d’une couche métallique, acier ou aluminium, et d’une couche de polymère. La première partie de cette thèse est consacrée à la caractérisation des plaques métalliques étudiées pour cette thèse : acier DP450 et aluminium AA2024-T3. Un nouvel essai de cisaillement séquencé est proposé afin d’identifier le comportement de la tôle en grande déformation. L’essai de traction à déformation plane est adapté pour identifier la déchirure des tôles en dynamique, jusqu’à des vitesses de déformation de l’ordre de 200/s. La deuxième partie est consacrée à l’identification complète d’une nouvelle résine polydicyclopentadiene (PDCPD) appelée Nextene. Dans la dernière partie, différentes structures multicouches sont sollicitées par des impacts à l’aide d’une catapulte qui projette des projectiles de 2.5 kilogrammes à une vitesses de 10 m/s. Leurs comportements respectifs à l’impact sont comparés et simulés numériquement
The protection of onboard electronic equipment has become a major issue in ensuring the safety of the combatant. We can cite various examples such as the protection of hydrogen cells in vehicles or in a soldier's onboard battery. It is in this context that the thesis is being carried out, studying multi-layers type of protection, solicited by fragment-type projectiles, weighing a few kilograms and at speeds of the order of 10 m/s. In order to ensure the commissioning of such protections, tests and simulations must be carried out over a wide range of stress states. The literature shows that multi-layer structures offer a good compromise between the ability to absorb impact energy and lightness. The studied sandwich is composed of a metallic layer, steel or aluminium, and a polymeric layer. The first part of this thesis is devoted to the characterisation of two sheet metals, namely a DP450 steel and AA2024-T3 aluminium alloy. A new sequenced shear test is proposed to identify the behaviour of the plate at large strains. The plane strain tension test is adapted to identify the dynamic failure of the sheets at strain rate up to 200/s. The second part is devoted to the complete identification of a new PDCPD resin called Nextene. An experimental campaign is carried out in order to identify the parameters of the SAMP behaviour law in the LS-Dyna software. In the last part of the study, structures are subjected to impacts in a catapult, using a 2.5 kilogram projectile at a speed of 10 m/s. Various combinations of sandwiches are compared, and the numerical simulation of the tests is proposed

The continuous development of space missions has put forward requirements for high performance, high reliability, intelligence, effective integration, miniaturization, and quick turn around productization of the electronic system of satellites. The complexity of satellites has continued to increase, and the focus of satellite competition has shifted from the launch of success shifts to communication capacity, performance indicators, degree of flexibility, and continuous service capabilities. So, the importance of onboard avionics system is becoming increasingly prominent. In the future, the advanced avionics system integrates most of the platform’s electronic equipment. The design level of the system largely determines the performance of the satellite platform. This chapter focuses on the application requirements of the new generation of intelligent avionics system for future communication satellites and adopts an “open” architecture of “centralized management, distributed measurement and drive, and software and hardware ‘modular’ design” to build a universal, standardized, and scalable intelligent avionics system.

A practical and innovative solution to answer the need for power in freight cars is presented. The lack of available electric power in the vast majority of freight cars limits the use of electronic devices such as measuring (sensor) systems, GPS tracking devices or active RFID tags. An energy harvesting system has been developed to keep a battery charged and electric equipment running. The basic idea is to generate power using the relative motion of the car suspension as an input, scavenging energy that is normally wasted as heat in the damping system. Based on a promising first generation unit used as a proof of concept, the current prototype is designed to fit inside a typical suspension spring (D5) and so, can easily be implemented in virtually any rail car. During laboratory tests, the system is capable of efficiently generating up to 80W of power, on quasi-continuous basis, with a sinusoidal input of 3/8 inch at 2Hz. Durability tests have also been conducted to ensure that the system can withstand the harsh railroad environment. Additionally, actual suspension displacement measurements have been used to replicate real conditions and forge a more precise idea of the behavior that can be expected once implemented in a rail car. With encouraging laboratory tests, the next steps are to further validate the system and to confirm the obtained results with field testing.

It is a common practice in electronic packaging to deploy onboard temperature sensing ICs for thermal health monitoring and control. The IT equipment industry has seen exponential increase in power and power density growth on devices and PCBs. In turn, more and more IC temperature sensors are used in highly complex algorithms and are expected to be highly accurate in predicting the local thermal conditions. In many cases they are even used to correlate to air temperature. However, care must be taken in understanding the different factors that influence the temperature readings of these devices. Some of the factors that have direct impact on the quality of the temperature reading include parasitic heating due to adjacent components and placement location, airflow condition, circuit design in connecting these devices to the board, accuracy and tolerance of these devices. In addition, because of the increase in component power density, the temperature difference between the device temperature, for example junction temperature, and board sensor temperature can be very different and the range can vary a lot as well. In this paper, thermal numerical modeling, as well as empirical work at the system and board levels, was performed to understand the implications of the temperature readings from these devices. Several of the commercially available onboard temperature sensing ICs are compared as well. It is the intention of this work to point out these areas in order for thermal and system design practitioners to intelligently use these devices appropriately. Also, a high-level environmental monitoring and control system (EMCS) policy is illustrated for highly configurable multi-board equipment.

Abstract One challenge for mobile robotics is the limitation of onboard processing power and the size of equipment required to accomplish basic tasks. While hydraulic pistons can generate high force output for various types of manipulation tasks, they require large equipment including the pistons, compressors, and the power sources in order to operate properly. For hydraulics to be applied to small to medium scale robots, the scale of the system needs to be as minimalistic as possible. For this purpose, we designed a single stage valve actuated robotic arm. Since system’s dynamic behavior is complex and only piston distance data is observable, a heuristic method, a Fuzzy Logic controller, is investigated. The goal is to create and optimize a system using a single piston and small compressor while maintaining effective control of the arm. Fuzzy Logic Controller system details, experimental setup and results are discussed for various motion profiles and finally its effectiveness is compared with a traditional PID controller approach. Robotics is a field that is constantly evolving and looking for creative new ways to provide solutions to new and old obstacles. One challenge for mobile robotics is the limitation of onboard processing power and the size of equipment required to accomplish basic tasks. The issue especially with smaller scale mobile robots is the lack of power and space on the robot to fit equipment and any critical apparatus for said equipment. While hydraulic pistons can generate high force output for various types of manipulation tasks, they require large equipment including pistons, compressors, and power sources in order to operate properly. Typically, a motor is used to power a pump which pressurizes hydraulic fluid. This fluid is used by the machine via hydraulic tubes and then is sent back through a filter and returns to the pump. This method of using hydraulics requires a large amount of power and a large amount of space. For hydraulics to be applied to small to medium scale robots, the scale of the system needs to be as minimalistic as possible. For this purpose, we designed a single stage valve actuated robotic arm. These employed the use of small electronic control boards fitted to the compressor system used to drive the hydraulics. For types of systems that must operate with discrete impulses of data to reach a target or reference value predominantly use Proportional-Integral-Derivative (PID) Controllers. These would be programmed in the onboard computer driving the hydraulic system. These systems require careful tweaking of various gain values to set up appropriately. However, the choice of an accurate controller structure relies on the application. Since system’s dynamic behavior is complex and only piston distance data is observable, an alternative method of control is investigated. Fuzzy logic is a control method which takes inputs from sensors and determines the output in terms of logical statements that can be in degrees between 0 and 1 rather than strictly 0 and 1 as seen in traditional Boolean logic. The particular equipment of interest in this study is a pneumatic robotic arm and all associated hardware. The goal is to create and optimize a system using a single piston and small compressor while maintaining effective control of the arm. Both a PID controller and a Fuzzy Logic controller were used to control the same system for the same set of tests. After PID control design approach is briefly discussed, Fuzzy Logic Controller system details, experimental setup and results are discussed for various motion profiles. Finally, the effectiveness of a traditional PID controller is compared to the effectiveness of a fuzzy logic controller.
