Abstract

Space systems are similar to their terrestrial counterparts in many respects but the main distinction that makes space system unique are due to the harsh and low gravity environment that space systems needs to survive, requirements of system redundancy due to lack of on orbit maintenance or parts replacement and costs associated with those. These put extra emphasis on systems and requirement engineering from the very early stage of systems development lifecycle. Typical space missions comprise of many interconnected systems and systems of systems. Each of these systems need to be satisfied or adhered to thousands of requirements. Traditional System Engineering (SE) approaches require updating and tracking requirements against their functional or behavioural components manually. On top of that, during early design review stages, mission system engineers may also needs to carefully modify or delete requirements without compromising effects of that on other interconnected or sub systems. This is a very time consuming and complex procedure especially when multiple stakeholders and teams of engineers involved locally or globally. This paper introduces the implementation of Systems Modelling Language (SysML) for modelling complex space robotic systems in context of On-orbit Serving (OOS) missions. In this paper, the benefits of applying Object Management Group (OMG) System Modeling language (SysMLTM) to support the specification, analysis, design and verification to space robotic systems is being proposed
