Abstract
Nanosatellite on-board software is a real-time system that schedules and executes control actions over the platform and the payload subsystems during the mission stages. Its development is a complex task that can be better approached using advanced software engineering techniques as graphical component based modelling and automatic code generation.Nanosat1B is a scientific nanosatellite developed by the Spanish National Institute of Aerospace Technology (INTA) that was launched on July 09. This paper introduces the component base modelling and automatic code generation of Nanosat1B on-board software using a CASE tool named EDROOM. It shows the UML2 diagrams used for specifying the system components, their interfaces and behaviour, emphasizing on their reuse possibilities on the same domain.The paper describes also the main characteristics of the EDROOM tool and analyses the feasibility of its adaptation for automatic Java code generation. The benefits of using the EDROOM automatic Java code generation for nanosatellites on-board software development are also enumerated.
