Wallops Electrical Engineering Branch, Code 569
Points of Contact
The Wallops Electrical Engineering Branch is responsible for conception,
analysis, design, development, validation, and implementation of
electrical/electronic, RF, microwave, and millimeter wave components
and systems in support of the Wallops Flight Facility missions,
projects, and technology initiatives.
Primary customers include
- Wallops Suborbital and Special Orbital Projects Directorate’s
- Sounding Rocket Program
- Balloon Program
- Aircraft Program
- Range and Mission Management Program
- University Class Satellite Project
- Shuttle Small Payloads Project
- Wallops Ground Network Project
- Earth Sciences Directorate’s Observational Science Branch at
The Wallops Electrical Engineering Branch provides world-class
expertise for development of both flight and ground instrumentation,
communication, and radar components and systems for Wallops ELV’s,
sounding rockets, aircraft, balloons, satellites, shuttle payloads,
ocean-borne payloads and support systems.
Design and development is provided for products and systems involving
- command and data handling systems
- power generation and distributions systems
- RF, microwave and millimeter wave telemetry, radar, and command
- antenna systems
- communications systems
- control systems
- data acquisition and storage systems
- pyrotechnic/ mechanism deployment electronics
Branch personnel work closely with the flight projects, the Mission
Services Ground Network Program(Code 452) and the Wallops Test
Range to develop these components/systems and their associated
infrastructure. They conduct theoretical studies, develop simulations
and models, and provide contractor oversight as required.
The branch partners with other Wallops and Greenbelt AETD branches
as well as other Centers and Government agencies on these development
efforts. The Branch also works with industry to develop next generation
space, airborne and ground electrical, communication and radar
components and systems.
Integration and Test capabilities are provided for technology
development efforts, project, and end-to-end mission system support
with skills in flight harness development; flight component electronic
packaging; airborne and ground telecommunication, radar, and instrumentation
systems, antennas, electromagnetic compatibility and RF interference
analysis; and ground system implementation.
Mission Engineering capabilities include
- spectrum management
- RF link budget analysis
- mission planning analysis
- consultation for evaluation of mission readiness, and systems
operation and maintenance performance
Representation is provided for membership to NASA Committees,
Range Commanders Committees, and the USAF Instrumentation Radar
Support Program involving spectrum management and range instrumentation.
Engineering expertise contributes to the conceptual planning of
future missions, experiments, and advancements in technology associated
with flight systems and supporting systems enabling experimentation
and science activities.
Facilities and Labs
Branch Laboratory Facilities include
Electronics, Microwave, and Telemetry Laboratories, a shielded
Dual-Mode Far Field/Compact Range Antenna Pattern Measurement Facility,
a shielded EMI/EMC Measurement Facility, and a 5.3 Meter Ka/S-Band
Technology Demonstrator Tracking Antenna System and Ground station.

Code 569 has led the development of several Mobile Range Instrumentation
Systems in recent years. Developed systems include telemetry data
acquisition and those providing command and control to ELV class
vehicles in the application of range safety. In addition, failsafe
power systems for mobile range power have been developed to help
ensure safe and successful mission conduct at remote launch ranges.
Mobile Command System 1A, Mobile Telemetry 7-Meter S-Band System,
and Mobile Power System #2 as deployed for support.
