%X Space mission implementation faces a very dynamic environment with 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 by the Brazilian Institute for Space Research (INPE).
