Eric Stromswold

Eric Stromswold, President and Chief Engineer

Eric has a B.S. in Mechanical Engineering, an M.S. in Aerospace Engineering, a Ph.D. in Materials Science, and 15 years experience developing spaceflight hardware. He played a key role in the development of the following attitude control systems:

• the very powerful, extremely low jitter 2 Nm reaction wheels currently controlling various large satellites, including the GeoEye 1 spacecraft that when launched was the highest resolution commerical Earth-imaging satellite ever to fly.
• the very small 0.006 Nm reaction wheels used to control various small spacecraft including the two Grail spacecraft that completed a precise gravity map of the moon.
• the tiny 0.31 Nms CMG used to control the attitude of the agile Violet Spacecraft.
• the huge 2300 Nms Next Generation Control Moment Gyro used by Naval Research Labs.

Robert Sullivan

Bob Sullivan, Senior Electrical Engineer

Bob has a bachelor's in Computer Science and trained at the US Navy at the Damneck Guided Missile School and at over a dozen other Navy electronics schools specializing in radio communication. He has a First Class FCC Repair License and over 30 years of experience in aerospace digital electronic design. Bob is a great design engineer and also has a unique ability to troubleshoot complex electronics problems. Many of Bob’s designs have flown in space, including:

• An ASIC controlled Communications Synchronization Unit that passes data between multiple satellites and corrects the timing between satellites to within 1.56 nanoseconds.
• A US government satellite’s “On Board Processor", which when launched was the fastest reprogrammable computer in space.
• An FPGA-based control system for the Reaction Wheels on the Grail Spacecraft.
• An FPGA control system for the Control Moment Gyros on the Violet Spacecraft.

Andy Irwin

Andy Irwin, Senior Mechanical and Systems Engineer

Andy earned his Bachelor of Science degree from the University of California, Berkeley. He has worked in a University Highway Research Lab and done nano-particle research. He played a key role in the design of ultra precision extreme pressure pumps, special material processing furnaces, thermal vacuum test chambers, reaction wheels for spacecraft attitude control, pressure vessels, industrial automation equipment, and even a special commercial cooking appliance. He brings to the table a remarkable breadth and depth of knowledge in Mechanical Engineering Specialties, Test Engineering, and Mathematics. His vast experience in a range of different industries and his commitment to keeping up with all of the latest engineering technology and manufacturing methods make him an invaluable contributor to any project and a great project lead.

Chris Murphy

Chris Murphy, Mechanical and Quality Engineer

Chris has a BS in Mechanical and Aerospace Engineering from Cornell University. He brings to the table nearly 30 years of experience with spacecraft attitude control components and critical aircraft systems. He has worked in Quality Engineering, Mechanical Design, Electronic Packaging Design, and Manufacturing Engineering to improve performance, lower costs, and ensure all designs survive years of operation under extreme vibration, shock, and thermal environments.

Steve Fox

Steve Fox, Business Development

Steve has been an aerospace systems engineer for over 40 years, and has extensive experience designing, testing, and providing operational support for space satellite Attitude Determination and Control Systems and related hardware. He played a key role in the development of space satellite hardware and systems for RCA Astro Electronics (Hightstown, NJ), INMARSAT (London, England), ITHACO Space Systems (Ithaca, NY), Teledesic (Kirkland, WA), OSC Space Systems (Dulles, VA), ITT Space Systems (Rochester, NY), Goodrich ISR Systems (Ithaca, NY, and Danbury, CT), among others. While at ITHACO, Steve was also responsible for business development, and was the primary contact for all domestic and international space related marketing issues, from casual customer telecons through the submittal of formal proposals. Steve has also authored / co-authored numerous formal publications in journals and conference proceedings in the areas of spacecraft attitude determination and control systems, attitude determination and control hardware, and satellite pointing and control performance.

Jim Krebs

Jim Krebs, Senior Electrical Engineer

Jim is an electrical engineer with 26 years experience building Space Flight Hardware. Hundreds of MTBs that Jim designed have flown in space. Jim has a B.S. and M.S. in physics and has also worked as an Electrical Engineer on Magnetometers, Reaction Wheels, and Conical Earth Sensors.


Terry Clark

Terry Clark, Quality Engineer

Terry has 36 years experience building Space Flight Hardware. Terry worked on some of the very first low residual moment MTBs to fly in space, including the huge 3000Am2 MTBs currently provided attitude control to the Hubble Space Telescope.



Earl Hotchkin

Earl Hotchkin, Assembler

Earl has 16 years experience building Space Flight Hardware, and has wound hundreds of MTBs that have flown in space.
