Flight Data Systems & Radiation Effects Branch, Code 561

Solar Dynamics Observatory Mission Operations Center


The Flight Data Systems and Radiation Effects Branch is responsible for providing technical expertise that meet program requirements in the areas of flight data systems engineering; radiation hardness assurance engineering; discipline engineering expertise; and technology development.

Flight data system products include spacecraft and instrument Command and Data Handling (C&DH) subsystem electronics and carrier electronics for experiment payload systems that perform command, control, and data handling functions. Flight data system development activities and services encompass requirements definition, design, analysis, verification, integration, test, and qualification of flight data system or subsystem hardware. Design activities include digital electronics design and verification involving extensive use of programmable logic devices such as field programmable gate arrays (FPGAs).

Radiation effects engineering products and services encompasses the use of space radiation models to predict mission radiation environments and assess extent of radiation exposure on shielded spacecraft components; radiation requirements definition; test of flight components for tolerance/hardness against total dose, displacement damage, and single event radiation exposure effects; analysis of the effects of radiation exposure on performance and reliability; and development of mitigation strategies.

Flight data systems and radiation effects discipline engineering expertise provides support to both in-house and out-of-house spaceflight projects, proposal efforts, anomaly/failure review boards and design reviews.

The Branch also spearheads development and research in the areas of advanced radiation-hardened component technologies (including microprocessors, mission unique data processing electronics, data interface devices, memories, and active devices); engineering processes and guidelines; architectures and data buses; and models and tools for radiation prediction and characterization.

The Branch also supports these efforts through partnering with industry, other government organizations, and academia. For more information on the Flight Data Systems and Radiation Effects Branch, visit the Flight Data Systems and Radiation Effects Branch Website.
