The FERMI on-board computer is a rad-hard avionics unit for deep space and mission-critical applications, featuring a dual-core CPU, an FPGA chipset and embedded mass memory. lt works in synergy with the customizable on-board software to previde full spacecraft and payloads control, all inside a compact 0.4U case.
With a wide variety of external interfaces and a low typical power consumption of 5W, FERMI OBC is particularly suitable for small satellite platforms where volume and power constraints are design drivers.
The powerful FPGA allows for built-in hardware acceleration when computational performance is a must-have. AII criticai components feature a TID rating of at least 100 krad (Si), SEL immunity up to 80 MeV-cm2/mg and SEU protection.

CPU Board
The CPU board provides the required interfaces and devices lo offer complete satellite control capability. lt features a Dual-Core LEON3FT SPARC V8 Processor with fault-tolerant memory controller, 20 Mbit EEPROM + 5 Mbit EEPROM, 256 Mbyte SDRAM, all EDAC-protected from SEU. The available interfaces include RS422, SPI, UART and GPIOs.
FPGA Board
The high-speed rad-hard FPGA acts as an extension of the CPU and can act as chipset for additional interfaces, hardware accelerator and mass memory controller, and can be used lo implement advanced payload management. lt features a 16 GB ECCcorrected mass memory, as well as SpaceWire, RS422, LVDS, SPI, I2C and GPIO interfaces.
The presence of this board is up lo the user.
On-Board Software
Specifically designed for Argotec’s on-board computers, the on-board software offers a ready-to-use environment based on RTEMS operating system. lt features built-in task manager, command and telemetry management as per ECSS.E-ST-70-41 C, data handling functions and suppor! for FDIR service. The custom BSP allows the user to develop its own application software lo meet mission-specific requirements.
