“…A fruitful landscape of academic studies has applied multi-atribute tradespace exploration methodologies [10] to find optimal design solutions and capture the values and weaknesses of space systems. The available works have not only been concerned with the design of traditional imaging constellations [7,8,11], but also opportunistic satellite federations [12], missions requiring formation flying and near-simultaneous measurements [13,14]. In general, early design decisions are encoded by computational tools to allow for the generation of a complete solution space.…”

“…These automatically-enumerated architectural candidates are then traded by modeling their functional traits in the context of a given target application and/or the requirements of the system. In multiple occasions, Model-Based System Engineering (MBSE) frameworks have been closely coupled with simulation tools [8,9,14] in order to feed the optimization process with system-level performance metrics such as revisit time, coverage, latency, capacity, or specific indicators related to the system's function. Integral tools tailored to the design and detailed simulation of satellite constellations have been proposed: for Earth observing systems [9,15]; as well as for space communication networks [7].…”

“…Considering qualitative attributes can also be done at different design levels, including the behavioral layer of a system. The work presented in [14], for instance, achieves resilient, risk-aware space architectures through the design of an activity planning executive, while trading-off multiple complementary qualities. In the context of distributed Earth observing systems, suitable system ilities for the assessment of DSS have been reviewed in [20], where the authors suggest their evaluation methods to be integrated into new DSS design tools.…”

Earth observation satellite programs are currently facing, for some applications, the need to deliver hourly revisit times, sub-kilometric spatial resolutions and near-real-time data access times. These stringent requirements, combined with the consolidation of small-satellite platforms and novel distributed architecture approaches, are stressing the need to study the design of new, heterogeneous and heavily networked satellite systems that can potentially replace or complement traditional space assets. In this context, this paper presents partial results from ONION, a research project devoted to studying distributed satellite systems and their architecting characteristics. A design-oriented framework that allows selecting optimal architectures for a given user needs is presented in this paper. The framework has been used in the study of a strategic use-case and its results are hereby presented. From an initial design space of 5586 potential architectures, the framework has been able to pre-select 28 candidate designs by an exhaustive analysis of their performance and by quantifying their quality attributes.

Technology development efforts in autonomy and cyber-defense have been evolving independently of each other, over the past decade. In this paper, we report our ongoing effort to integrate these two presently distinct areas into a single framework. To this end, we propose the two-player partially observable stochastic game formalism to capture both high-level autonomous mission planning under uncertainty and adversarial decision making subject to imperfect information. We show that synthesizing sub-optimal strategies for such games is possible under finite-memory assumptions for both the autonomous decision maker and the cyber-adversary. We then describe an experimental testbed to evaluate the efficacy of the proposed framework.

Towards Architecture-wide Analysis, Verification, and Validation for Total System Stability During Goal-Seeking Space Robotics Operations

In this paper we discuss the beginnings of an attempt to define and analyze the stability of an entire modular robotic system architecture -one which includes a three-tier (3T) layer breakdown of capabilities, with symbolic, deterministic planning at the highest level. We approach the problem from the standpoint of a control theory outlook, and try to formalize the issues that result from trying to quantitatively characterize the overall performance of a well-defined system without a need for exhaustive testing. We start by discussing the concept of bounded-input bounded-output stability, giving examples where the technique might not be sufficient to guarantee what we term "total system stability" due to complications associated with the levels of abstraction between the modules and components that are being chained together in the architecture. We then go on to discuss necessary conditions that may fall out of this naturally as a result. We further try to better-define the input and output constraints needed to guarantee total system stability, using an assumption-guarantee-like contractual framework that sits alongside the architecture; the requirements then may have influence across multiple modules, in order to keep consistency. We also discuss how the structure of the architectural modules may help or hinder the process of capability characterization and performance analysis of each module and a given architecture configuration as a whole. We then discuss two overlapping methods that, combined, should allow us to analyze the effectiveness of the architecture, and help towards verification and validation of both the components and the system as a whole. Demonstrative examples are given using a specific architectural implementation called the Resilient Spacecraft Executive. In future work, we hope to define both necessary and sufficient conditions for total system stability across such a system architecture for robotics use.
