About
ABACUS is an OBC (On-Board Computer) subsystem with a general-purpose hardware platform, suited for a wide range of satellite and CubeSat missions. It is designed to be flexible and scalable in terms of processing power, with the goal of maintaining very low power consumption. The two cores (MCU MSP430 and FPGA Spartan-3E, interconnected via a 24-line bus) offer many operating modalities (e.g. Master/Slave or multi-Master), and the FPGA offers all the advantages of RTL coding for implementing specific tasks (e.g. attitude control) or generic systems, including third-party IP cores. With the FPGA, high reliability may be achieved using triple modular redundancy (TMR) configuration codes. Several embedded sensors provide health monitoring and attitude control data (3-axis magnetometer, accelerometer, gyroscope). The system design offers the possibility to reconfigure the FPGA code and MCU firmware in flight. ABACUS has reached more than six years of continuous flight heritage on UniSat-6, TigriSat and UniSat-7.
