Search for economically efficient options in creating research satellites are aimed at simultaneous satellites weight and size reduction and at their service life expansion. The experience of space mini-laboratories both active Kolibri-2000 , Mozhaets-4 , Universitetski-Tatyana and being created Kompas-2 , Chibis demonstrated thС trend to a sharp project budget reduction with the simultaneous information demand increase. It is possible only if nano-satellite technologies are applied. Application of high-efficiency photocells, new radio-engineering developments, digital signal processing technologies enables piggy-back launching 5-20-kg satellites. Launch cost reduction, use of ready-made optimum options and service bus cost enables creating one-experiment satellites selecting the required satellite configuration on construction-set principle. For example, now a research satellite with the following performance specifications is feasible: Weight 10 25 kg, including research equipment - 2 8 kg. (Depending on the actual objective). Average power-consumption 30 W. Peak power-consumption 60 W. Maximum solar battery generated power 60 W. Battery capacity 5.8 Ah, LiIon. On-board power voltage 10.0 14.3 V. Attitude determination three-axis, attitude determination accuracy - 0.5 degrees, stabilization accuracy 0.05 deg/s, rotations in three axes in inertial co-ordinate system. Service radio-link 145/435 MHz, 1200/9600 bps. Mission radio-link 8192 MHz, 32 Mbps. Maximum service equipment power 9 W. Average service equipment power-consumption 6 W. Hot ammonia on-board propulsion system may be installed for orbital correction. Therefore, it is appropriate to create a joint research programme for annual launches of Russian university community research and educational satellites based on nano-technologies and low-budget launches for holding on-going research.
