We developed an integrated attitude and orbit control system (AOCS) module for advanced CubeSat missions. The module is 1U and 1kg and is installed with all sensors and actuators required for accurate three-axis control. The target attitude control accuracy is 10 arcsec, which is the same as for other existing integrated AOCS modules, such as XACT and iADCS. In addition, we strongly focused on the transparency and expandability of the software from the user's viewpoint, and we decided to use open-source software for flight software and ground testing tools. This study shows an overview of the hardware and software design of the module. The development of the engineering and flight models was completed, and the hardware tests were successfully executed. The flight algorithms were developed based on the open-source software C2A and tested with the open-source simulator S2E and ground station software WINGS. These design and development results show the effectiveness of the open-source strategy in improving the transparency and expandability of the AOCS module.
