This paper shows the design concept and the preliminary report for the low-accuracy three-axis stabilization results of the newly developed standard micro satellite system. The standard bus system is developed by the University of Tokyo and NESTRA (next generation space system technology research association) supported by the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST Program). The satellite system tries to be straightforward to achieve cost-effective and short development period. The standard satellite systems are used as the bus system of three satellites launched in 2014, which are UNIFORM-1, HODOYOSHI-3, and HODOYOSHI-4. All of them have been achieved the low-accuracy three-axis stabilization, by dealing with the unexpected problems with the use of the modified operational plans. This paper also performs the comparison of the on-orbit results of three satellites and discusses the design feasibilities of the proposed bus system.
