Our mission is to deliver secure time and location solutions to complement and enhance existing solutions - including GPS.

Satelles provides unique timing and location solutions delivered over the Iridium® constellation of 66 low-earth-orbiting satellites. These timing and location signals are available anywhere on Earth, without the need for local infrastructure, making the system perfect for complementing GPS and other location-based technologies. Unlike standard GPS, these high power signals can reach into many building structures. Most importantly, Satelles has customized the Iridium signal-in-space to provide a location-specific signature that can reliably prove (or authenticate) the location of a mobile device or other equipment, while being virtually impervious to spoofing and other attacks.

Our Name

Satelles: in Latin means 'attendant' or 'guard' in the singular. In the plural, the word additionally means 'escort', 'suite', or 'train'.

Additional core competencies include: autonomous vehicle control; high-precision measurement and control; ultra low-noise electronic design; satellite-system design and prototyping; embedded system design and analysis; algorithm prototyping, development and implementation; agile embedded software development.



Michael O’Connor

Dr. Michael O’Connor is the CEO of Satelles, and was a founding member of the Board of Directors of iKare Corporation (from which Satelles has spun out).

Michael is a recognized pioneer in the booming field of precision agriculture. While a graduate student at Stanford University in 1994, Michael led the team that invented the world’s first farm tractor steering control system using GPS. Upon graduation in 1997, Dr. O’Connor co-founded IntegriNautics (now Novariant, Inc), where he and Greg established the AutoFarm business and brought the first products based on this technology to market. This work formed the basis for what is now a $500M+ global market. As Novariant grew to 150+ employees and successfully raised over $70M in venture capital, Michael served in a variety of executive roles at the company, including CTO, Vice President of Business Development, and CEO.

In recognition of his visionary work, Michael has been honored by Technology Review Magazine as one of the world’s Top Young Innovators, and was included in GPS World Magazine’s inaugural list of 50 Faces to Watch in GPS. Dr. O’Connor has also been inducted into the Space Technology Hall of Fame.

Michael received his Bachelor’s degree in Avionics from M.I.T., and his Master’s and Ph.D. in Aeronautics and Astronautics from Stanford University. In addition to his role at Satelles, Michael is currently a Technical Advisor to Peloton, Inc.

President & CTO

Greg Gutt

Gregory Gutt (pronounced gūt) is the President and Chief Technology Officer of Satelles.  Satelles is focused on delivering Satellite Time and Location (STL) a resilient PNT capability delivered via the Iridium Satellite Network (the largest satellite network in the world).

Greg received his Ph.D. from Stanford University in the field of electrical engineering (1997). His advisors were Prof. Gene Franklin and Prof. Brad Parkinson.

After Stanford, Greg became a founder and VP of Engineering at IntegriNautics Corporation (later renamed Novariant). Greg led a team to develop precision GPS guidance systems for farm tractors. The success of that endeavor transformed the company. Greg was the first President of the Autofarm focused company. Later, Novariant became the market leader in high accuracy GPS guidance systems for farming and later merged with AgJunction.

In 2001 Greg accepted a position with The Boeing Company and soon became a Technical Fellow. At Boeing, he was the principle creator of the ‘Boeing Time and Location’ technology.  Satelles now holds an exclusive commercial license for this technology.

Greg holds over 40 patents in the areas of: satellite navigation, guidance and integrated circuits. Numerous other patent applications are pending. His awards include: Boeing Breakthrough Achievement Award 2008; Boeing Technical Fellow 2006; Space Foundation – Space Technology Hall of Fame, Certificate of Commendation for AutoFarm System, 2006; Boeing Innovation Award for Technical Leadership 2005.

Chief Navigation Architect

David Lawrence

Dr. David Lawrence is the Chief Navigation Architect for Satelles. He joined Satelles in 2010 and has focused on signal processing and navigation algorithms. Before joining Satelles, David worked for 15 years at Novariant Corporation (previously IntegriNautics) where he was one of the founding engineers. His first role at Novariant was to adapt the IBLS aircraft landing system for TUAV applications. Subsequently, David worked on GNSS navigation processing including SPS, RTK, SBAS, Omnistar integration, attitude, ground-based augmentation systems, and inertial integration.

He was the primary navigation algorithm and software developer for GNSS phase processing used in all aviation and agricultural products at Novariant and prototyped the positioning software for mining products. He spearheaded the development of the first Novariant GPS receiver designs which were the basis for all subsequent Novariant navigation products. He was the technical manager and primary software developer for the X-31 landing navigation system.

David received a B.S. with distinction from Cornell University, a M.S. and Ph.D. from Stanford University’s department of Aeronautics and Astronautics where he won the Hoff Award for outstanding masters degree student. He has been an author on over 20 technical publications and an inventor on 30 patents.

At Stanford, David developed the real-time positioning architecture and software for a successful demonstration of 737 automatic landings using GPS and provided the capability to perform in-flight accuracy assessment for WAAS.

Before Stanford, David worked for IBM where he created physical models and control systems for computer animation applications. While at Cornell, David worked for General Electric Astro Division doing thermal analysis for the EOS program and requirements traceability for the APAE element of Space Station Freedom.

Chief User Equipment Architect

Stewart Cobb

Dr. Stewart Cobb is the Chief User Equipment Architect for Satelles. Stu joined Satelles in 2011 and brings a wealth of expertise and hands-on experience in designing, building, and testing GNSS and other RF hardware receivers.

After earning his undergraduate degree from MIT in Aero/Astro Engineering (Avionics), Stu served six years as an Air Force officer, working with the Space Shuttle at NASA and with experimental spacecraft in Los Angeles. During his military service, he earned an M.S. in Systems Management from USC. He then returned to school full-time, earning M.S. and Ph.D. degrees in Aeronautics and Astronautics at Stanford University. His dissertation demonstrated that inexpensive ground-based GPS transmitters (“pseudolites”) could be used to navigate aircraft with centimeter-level accuracy and “nine nines” integrity (less than one chance in a billion of an undetected failure).

Stu helped found IntegriNautics (now Novariant) to commercialize this technology. He led the design team for four generations of pseudolites and five generations of GPS and GNSS receivers, intended for precision guidance of aerospace and ground vehicles. One pseudolite system he developed was sold to Trimble Navigation and is now part of their Mining Solutions product line.

Stu holds a private pilot license and an Extra-class amateur radio license. He is named on at least 18 patents in the fields of satellite navigation and precision guidance and is a co-author of the textbook GNSS for Vehicle Control.
