SPROUT is a nanosatellite demonstration mission of Nihon University, Tokyo, Japan. The prime objective is to test the deployment of a combined membrane structure (1.5m-sided triangular membrane supported with two space-inflatable tubes) and 3-axes attitude control technology. A further goal of the mission is to perform the demonstration experiment of the ADCS (Attitude Determination and Control Subsystem) of a nanosatellite with a large membrane structure by using in-house manufactured magnetic torquers and COTS sensors.
