Paul Lego

Paul Lego

Paul is an entrepreneur and CEO with over 25 years of senior executive experience in Silicon Valley. Prior to joining Coherent Navigation, Paul was most recently CEO of Bespoke Innovations, a medical devices company using 3D scanning, 3D CAD and 3D printing technologies to design custom orthopedic devices. Bespoke was acquired by 3D Systems, Inc. (NYSE:DDD) in May 2012. Prior to Bespoke, Paul was CEO of Dash Navigation, a venture-backed start-up in the automotive GPS navigation market that was sold to RIM (now Blackberry) in the spring of 2009. From 1996 to 2003, Paul was chairman and CEO of Virage, a provider of video and rich media communications software and services. Virage went public in 2000, was bought by Autonomy in 2003 and is now part of Hewlett Packard. Prior to Virage, Paul was COO at Digidesign, a manufacturer of digital audio recording systems. Digidesign went public in 1993 and was bought by Avid Technology in 1994. Paul has also held positions at Pyramid Technology, General Electric, and Digital Equipment, and worked as an EIR at Sutter Hill Ventures and Trinity Ventures.

Paul received his MBA from the Harvard Business School in 1984, and a BSEE degree from Cornell University in 1980. He was a member of the board of trustees of the San Francisco Ballet from 1996 to 2009 and a member of the Young Presidents Organization (YPO) from 2001 to 2010.

Bill Bencze

Bill Bencze

Bill received his B.S. in Electrical Engineering from Stanford University in 1989, followed by a Ph.D. in 1996 with specializations in precision instrumentation and automatic control systems. Following graduation, he served a number of roles on the NASA/Stanford Gravity Probe B Relativity Mission (GP-B), a fundamental physics experiment in orbit designed to test Einstein’s theory of General Relativity to unprecedented precision. As part of GP-B he developed the flight electrostatic suspension systems for the mission’s electrostatically-suspended ultra-precise gyroscope sensors, served as the overall electronics systems manager for the GP-B spacecraft prior to launch, and Program Manager following launch during the mission operations data analysis phases of the mission. He is a co-inventor of the HIGPS technology and left Stanford University in 2008 to co-found Coherent Navigation to explore the technical potential and applications of HIGPS. Bill’s technical expertise includes hybrid control systems, gravitational and inertial reference systems/inertial sensors, radio navigation and timing systems, and precision instrumentation systems for space borne and terrestrial high reliability applications.

Rob Brumley

Rob Brumley

Rob has been leading teams in developing transformational cutting-edge precision systems for nearly 20 years. He received his B.S. in Physics, M.S. in Electrical Engineering, and Ph.D. in Electrical Engineering degrees from Stanford University. While at Stanford, he served in various positions at NASA’s Gravity Probe B program, a space-based physics experiment that used cryogenic superconducting gyroscopes to test several key aspects of Einstein’s Theory of General Relativity. While at Gravity Probe B, he led the Gyroscope group, delivering a flight gyroscope with a drift rate 10 million times smaller than the best Earth-based gyroscopes. Later, he became Payload Manager, responsible for the integration and test of the science payload. Finally, he served as Deputy Program Manager, Technical, responsible for all operational and technical aspects of the program from spacecraft integration and test, launch, and initial on-orbit checkout.

In 2005, Rob became interested in the potential of augmenting the Global Positioning System with signals from low-earth orbiting (LEO) communication satellites, and moved to Boeing to help found the HIGPS program there. While there, he founded the HIGPS Integration and Tests group. He was also, along with other Coherent Navigation principals, an inventor on 8 GPS augmentation patents. In 2010 he jointed the team at Coherent Navigation dedicated to creating the next generation of navigation technology.

Brent Ledvina

Brent received a B.S. in Electrical and Computer Engineering from the University of Wisconsin at Madison in 1999 and a Ph.D. in Electrical and Computer Engineering from Cornell University in 2003. He also holds an adjunct faculty position at Virginia Tech in the Bradley Department of Electrical and Computer Engineering. As an academic, he developed the first publicly-acknowledged civil GPS spoofer. His research interests are in the areas of ionospheric physics, space weather, estimation and filtering, software-defined radios, and GNSS security. He has authored or co-authored 36 technical publications. He is listed as inventor or co-inventor on 16 pending and issued U.S. patents.

Brent spends his time leading internal and external technical programs at Coherent Navigation and carrying out business development activities.

Isaac Miller

Isaac Miller

Isaac is a problem solver, system architect, and technologist with more than a decade of experience designing GNSS and high-precision navigation algorithms for real-time field applications.  He has worked at Coherent Navigation since 2009, where he currently serves as CTO and also program manager and system architect for Coherent Navigation’s Iridium-based high-precision navigation service.  In the past, he’s led Coherent Navigation’s High-Integrity GPS (HIGPS) user equipment group and also acted as lead system architect and algorithm developer for HIGPS user equipment, where he designed and implemented ultra-tightly-coupled GPS / Iridium / INS jamming-resistant positioning algorithms that have since been independently tested in a wide variety of operational environments.

Prior to joining Coherent Navigation, Isaac was a visiting faculty member at Cornell University in 2009 and a team principal for Cornell University’s 2007 DARPA Urban Challenge team and 2005 DARPA Grand Challenge team.  On those teams, Isaac designed and implemented localization, environment perception, estimation, and control algorithms for two full-size, fully-autonomous robotic vehicles: one that operated on-road in live traffic, and another that operated off-road in a harsh desert environment.

Isaac received his Ph.D. from Cornell University in 2009, his M.S. from Cornell University in 2006, and his B.S. from the California Institute of Technology in 2003, all in Mechanical Engineering.  His technical expertise includes artificial intelligence, Bayesian estimation and Kalman filtering, computer vision, machine learning, probabilistic robotics, attitude and position estimation, GPS/GNSS, target tracking, celestial mechanics, controls and dynamics, mechanical vibrations, and dynamic modeling and simulation.
