Software

Members of our Future Technologies group are actively involved in software development. Over the years, we have developed or made sizable contributions to the following software packages:

Programming Models, System Software

¹⁾ Roth was part of the Autopilot development team when it was a product sold by Chen Systems, Inc. Autopilot is now sold and maintained by KBS Software, LLC.

²⁾ Olaf developed GPS while at NASA Langley Research Center, Hampton, VA assisted by NASA contractor Majdi Baddourah, now at ARAMCO in Saudi Arabia.
