The SatBus 3C2 from Kongsberg NanoAvionics is a Satellite On-Board Computer (OBC) which is highly integrated nano-satellite main bus unit containing advanced functionality such as OBC, ADCS and redundant UHF communication system (COMM). It is designed for small-sized satellites and complies with the CubeSat standard. This low power OBC has a clock speed up to 400 MHz integrated with 1 MB RAM, 2 MB FLASH and NOR FLASH of 256 MB. The Main Bus Unit consist of ADCS, including necessary sensors and actuators such as Sunsensors, reaction wheel, GPS receivers, and SatCOM UHF. It has multiple CAN, SPI, I2C and UART/USART interfaces. It has a space heritage of low earth orbit missions.
