Typical aerospace embedded computers have many characters in common, especially in the aspect of the design of computer architecture. To evaluate this category of computers, 3 typical aerospace embedded computers were sampled and their characters of architecture and common technology were analyzed. Eight characters of architecture were concluded, and three evaluation dimensions were proposed. A basic guideline and a practical reference value or design were attached to each architecture character. The relationship was analyzed among the final assessment result, the evaluation dimensions and the architecture characters. Any aerospace embedded computer can be scored according to the assessment model for various estimate requirements. The evaluating method and progress were illustrated through one kind of advanced aerospace embedded computer's evaluation case. The case indicates that the assessment model is clear, effective and practical. It can provide some guidance for the design and performance analysis of aerospace embedded computers.

In a recent proof of concept demonstration, ManTech verified the ability to accurately quantify cyber effects within an operational scenario. In particular, we defined and then captured cyber/ net-centric metrics to assess the relative impact of non-kinetic influences within a maritime domain mission. To accomplish this, we utilized representative systems performance data and employed established Modeling and Simulation (M&S) tools to generate accurate physics-based data. The data were imported into a cyber range environment and the representative network modeled. Via constructive simulation, we established an analytic baseline and then conducted sensitivity analysis to compare relevant cyber/net-centric measures of effectiveness. Of note, our subject matter experts performed this analysis by adapting existing tools and produced meaningful results in a matter of days, rather than weeks or months. [ABSTRACT FROM AUTHOR]

Today, almost all command, control, communications, computer, intelligence, surveillance, and reconnaissance (C4ISR) systems are acquired via spiral development. In order for these systems to support warfighter missions, they must be networked together with various weapon systems. Current operational testing is generally dedicated but limited in scope and is conducted by stimulating the system under test with master scenario event lists. Such testing is not fully operational and does not focus on effectiveness in accomplishing the warfighter mission. This article proposes a strategy to improve the operational realism of testing net-centric C4ISR systems. The strategy is based on the United States Department of Defense's lessons learned from the Year 2000 operational assessments conducted in 1999 in all combatant commands. Developmental C4ISR systems can be deployed in the field but isolated from real world operations using different crypto for the networks. Thus, the systems can ride on operational networks and use real-world combatant command databases, but using different crypto and hence not mixing in real-world operations. In this strategy, the systems being tested with supporting networks and databases can be assessed to support the warfighter mission in a field training exercise. The feasibility of this strategy is now possible because of the improved net-centric environment in the field today. This strategy can also deal with interfacing coalition C4ISR systems, which are generally excluded during testing today. [ABSTRACT FROM AUTHOR]
