Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Soft&hardware device for support and monitoring of small spacecraft rotational motion parameters A.V. SEDELNIKOV, A.S. FILIPPOV, Yu.Ya. PUZIN, K.E. VORONOV, A.V. PIYAKOV In paper the concept of development of the soft&hardware device intended for monitoring of parameters of its rotational motion is described. Experience of ground, flight tests and maintenance of flight is used for development of soft&hardware device and experimental “Aist” small spacecraft is sample. This experience allows to draw conclusions about feasibility of these or those decisions and approaches and also to develop algorithms of effective operation of soft&hardware device. Results of operation can be used in case of design of the small spacecraft which do not have full-fledged management system and exploited in nonoriented flight. They are partially implemented and tested in case of tests and maintenance of “Aist – 2D” small spacecraft. Keywords: small spacecraft, soft&hardware device, parameters of rotational motion, magnetic executive bodies, magnetic measuring instruments.
