Recently small satellite development activities became popular throughout the world and the number of satellites being developed and launched a year is becoming larger. The Space Robotics Laboratory of Tohoku University has been developing multiples of micro-satellites for years and has gathered experiences in their development, verification, integration, and operation. SRL has recently started development of model-based simulation, verification and integration environment to realize rapid and cost-effective development of reliable micro-satellites. The conceptual design and its functionality have been verified through the real-life 50kg class micro-satellite projects. The developed environment can be utilized in different configurations depending on requirements in each satellite development phase. This environment is designed to be modular and very flexible and can be utilized for other micro-satellites and possibly even much smaller space system projects in the future. The forth micro-satellite of SRL, which is named RISESAT (Rapid International Scientific Experiment Satellite), introduces Space Plug-and- Play Avionics standard for payload instruments' electrical architecture. By applying a virtual system integration technology, remote integration of satellite components spread all over the world via internet becomes possible without getting together at a certain place. In this way the integration of a variety of scientific instruments becomes simple and the effort required can be dramatically reduced. According to this background, SRL started investigation of extending above mentioned model-based simulation environment for SPA compatible instruments. This environment shall enable software-based simulation and early functional verification of the SPA devices together with the satellite's bus system. This will improve the rapid and cost-effective development performance of small satellites which introduces SPA technology. Copyright
