“…This radiation might be in the form of high energy particles (protons, neutrons, alpha and beta particles) or ionizing electromagnetic rays from ultraviolet to X-rays that leads to a Total Ionizing Dose (TID) of approximately 1 krad/year (data calculated using SPENVIS [12] with a 3 mm Al shielding). Due to the orbit, and the short assumed lifetime of the mission (3 months), total dose effects have not been considered (see, for instance, [13] for an analysis of the behavior of the Texas Instruments MSP430 microcontroller under radiation). However, single-event effects (SEE) such as latch-up occurring in CMOS devices, and state upsets in memories and/or registers of digital circuits, might indeed induce wrong behaviors or even permanent faults.…”

Many universities are now involved in projects related to design, assembly, and operation of small satellites. These projects, with participation of researchers and students, and support of external companies, do not aim to compete with commercial satellites; the main goal is to increase the experience level which contributes to make space applications affordable also to small organizations. For students, participation in the complete process of satellite design, assembly, and testing, offers a unique experience within an interdisciplinary complex project. External companies are involved in creating a community of researchers focused on space applications, thus creating new markets and opportunities. The paper describes the architecture and design solutions of a small satellite developed at Politecnico di Torino in the above mentioned context. The main design goal was to combine the usually conflicting cost and reliability constraints; cost has been limited by using properly selected COTS (Commercial Off The Shelf) devices. Reliability has been achieved through redundancy and design diversity. Focus of the paper is on overall satellite design and architecture, with details of solutions to enhance reliability down to the hardware level. The experience led to the development of a new course (Master level) and to several new projects currently under way.

“…To incorporate this scheme in the optimization problem, consider a subset of agents' indices that share the same trajectory (orbit o) {j 1 and choose the one that has the best resultant cost function. This method is impractical when dealing with a large-scale system, and to avoid this cumbersome process, an approximate approach should be taken into account.…”

“…Challenging problems in multi-sensor management systems arise when the sensors operate in a dynamic environment, and they should be repeatedly moved to perceive the desired physical quantities of non-stationary targets. In such a multi-agent system, in order to leverage resources more efficiently, a meticulous plan of action is required to distribute tasks among the agents [1].…”

This paper develops a robust optimization-based method to design orbits on which the sensory perception of the desired physical quantities are maximized. It also demonstrates how to incorporate various constraints imposed by many spacecraft missions, such as collision avoidance, co-orbital configuration, altitude and frozen orbit constraints along with Sun-synchronous orbit constraints. The paper specifically investigates designing orbits for constrained visual sensor planning applications as its case study. For this purpose, the key elements to form an image in such vision systems are considered and effective factors are taken into account to define a metric for perception quality. The method employs a max-min model to ensure robustness against possible perturbations and model uncertainties. While fulfilling the mission requirements, the algorithm devises orbits on which a higher level collective observation quality for the desired sides of the targets is available. The simulation results confirm the effectiveness of the proposed method for several scenarios involving low and medium Earth orbits as well as a challenging space-based space surveillance program application.

Abstract-NASA aeronautical programs require integrated vehicle health monitoring (IVHM) to ensure the safety of the crew and the vehicles. Future IVHM sensors need to be small, light weight, inexpensive, and wireless. Surface acoustic wave (SAW) technology meets all of these constraints. In addition it operates in harsh environments and over wide temperature ranges, and it is inherently radiation hardened. This paper presents a survey of research opportunities for universities and industry to develop new sensors that address anticipated IVHM needs for aerospace vehicles. Potential applications of passive wireless SAW sensors from ground testing to high altitude aircraft operations are presented, along with some of the challenges and issues of the technology.
