In this article, design and analysis of an optimal orbit control for a communication satellite is investigated. It is the challenging task and critical importance to control the orbit of a communication satellite especially the one used for worldwide communication. The main objective of this work is to evolve a design based on modelling and simulation of an optimal orbit controller for a satell...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Multi-Attribute Tradespace Exploration (MATE) for Survivability is introduced as a general methodology for survivability analysis and demonstrated through an application to a satellite radar system. MATE for Survivability applies decision theory to the parametric modeling of th...

This paper gives an insight to some of the intrinsic issues related to the understanding and the computer support of conceptual design. On the one hand, the academic research and development have produced innumerable methods and techniques to support product conceptualization. Reasonable progress has been achieved in (a) the understanding of the fundamental reasoning mechanisms, (b) the develop...

This paper introduces new approaches to the conceptual design of electro-mechanical systems from qualitative specifications of behaviour and function. The power of these methods stems from the integration of techniques in qualitative physics, symbolic mathematics , computational geometry and constraint programming. This is illustrated with an effective kinematic synthesis method that integrates...

At the beginning of the space conquest the space-systems were composed of unique satellite. With the growth of the needs and the explosion of the technologies, the space-systems became more and more complex. Now they are composed of many satellites working together : we talk about constellation. The aim of the constellation design, is to optimize the satellite positions in order to obtain the b...
