Aalto University has recently started the design and construction of a small nanosatellite called Aalto-1. Aalto-1 will be the first complete and Finnish satellite in space. The plan is to base the satellite on the CubeSat standard, to launch it as piggy-pack on a larger satellite, and to use mainly students! for the design and construction of the satellite. Aalto-1 could thus be called also as StudentSat.

The task of the University of Turku in this project, coordinated by the Aalto, is to design and build a radiation detection instrument RADMON to Aalto-1. The work is done together with the University of Helsinki and with the Finnish Meteorological Institute. The team in University of Turku, Department of Information Technology and Space Research Laboratory, will design the logic and software for the RADMON data collection and processing, and will participate to the design of  the communication between the instrument and the spacecraft. In addition the team will design a prototype for the ground-support equipment, computers and software controlling RADMON operations and receiving data from the spacecraft. The development work will be integrated to the teaching as far as possible. The plan is also in Turku to use mainly students for the development of the RADMON.
