                         fast-paced information technology advancement and shrinking space 
                         budgets. A more focused use of decreasing public investments in 
                         space requires a cost reduction over their entire life cycle, up 
                         to the end of the useful life of a spacecraft. The anticipation of 
                         cost, schedule, risk and performance requirements from all over 
                         the product life cycle to the early stages of product development 
                         is generally recognised as a necessary condition to reduce life 
                         cycle cost. In order to cope with the intrinsic functional 
                         complexity of space products, such requirements engineering 
                         activity must be performed in a structured way within a systems 
                         engineering approach. This paper aims to describe how Cradle, a 
                         commercial systems engineering environment software package, can 
                         be used for integrated satellite development, taking into 
                         consideration functional and life cycle process requirements. 
                         Cradle has requirements management, system modelling, performance 
                         modelling, configuration management and document generation 
                         capabilities integrated in the same environment. Also, the paper 
                         provides some examples of application and highlights how Cradle 
                         can enhance the satellite development related activities performed
