A microsatellite for solar wind monitoring

Solar wind monitoring at the upstream L1 location is an essential part of the space weather observation system. Such modern spacecraft are relatively large and carry diverse science instruments. We suggest the concept of the microsatellite-scale monitor, having onboard only the essential instrument set. Such a spacecraft may solve a task of multipoint measurement in order to capture slanted or spatially localized structures. We discuss an optimal instrument set, radio-communication and attitude control systems as well as economical ways of launch and transfer trajectory.
