Overview

The flight computer (OBC), developed jointly by CONAE and VENG S.A., is a complex electronic unit, developed to manage satellite mission instruments, with data transfer rates of up to 100 Mbps, in addition to providing general-purpose RS-422 bi-level interfaces, analog channels for the acquisition of voltages and temperatures (housekeeping information, both internal to the unit and external) and the ability to command up to 24 heaters, through opto-coupled outputs. It has a power module, a module based on the 32-bit UT699 LEON3-FT processor and 6 additional functional modules, all linked through the cPCI 2.2 standard using a Backplane. In addition, it has an additional slot, designed to adapt to the needs of different missions/projects.
