Broad Reach Engineering C&DH Spacecraft Avionics

- - Command and data handling units


Broad Reach Engineering Advanced Avionics Systems are based on 3U boards designed specifically for spacecraft & payload applications. Systems are available for C&DH, EPS, integrated C&DH & EPS, or payload applications. Design options include single string and redundant systems.		All avionics are tailored to meet the mission requirements. Existing designs are drawn on where advantageous and new designs are created where significant benefits may result.		All BRE Avionics designs adhere to the highest standards in space flight hardware design. Space qualified parts are used throughout unless special requirements dictate otherwise and all design methods are tailored specifically with space flight environmental and functional requirements in mind.

Software Development Unit

Engineering unit versions with flight like commercial CPUs are available as software development units (SDU) for customers who would like to evaluate the architecture and/or would like an early start on software development tasks. SDU Boards are form, fit, and function compatible to the actual flight hardware but are not subjected to flight like testing and utilize some commercial part equivalents, such as FPGAs, memory, and commercial chassis. SDUs provide an effective development platform that is available at a reduced schedule compared to full engineering or flight units. SDUs are available with various CPU versions, ethernet support and various interface boards. Software support, including drivers is available for VxWorks and other operating systems.
