Executive Leadership at RASTRAC


Jeff Manning, President

Jeff Manning founded Manning NavComp, Inc. in 1993, with a vision to apply an elegant software layer over the technologies of the Global Positioning System and wireless data networks, giving people in many diverse environments the ability to remotely supervise their important assets. His background of eight years as a senior engineer with Raytheon E-Systems prepared him for the technological task that has evolved during the last fifteen years. Manning received the Bachelor of Science degree in Electrical Engineering from The University of Texas in 1987, and the Master of Science Degree in Electrical Engineering from The University of Texas at Arlington in 1990. Manning is convinced that the values of hard work, integrity, education, and humility are all very real, and actively applies those values to the philosophy of the company.

Robert W. (Bob) Thompson, Chief Executive Officer

Robert Thompson began his mapping and surveying career at the University of Wisconsin, then spent 2 ½ years in the Antarctic creating the first aeronautical charts in the early 1960s. He served in several positions at Sanborn Map Company, Pelham, NY where he managed several early geographic information systems. In early 1970, Bob was VP, Marketing for Utility Data Systems in Houston, with digital mapping projects like the Tennessee Gas Pipeline, oil wells in California and the earliest fully computerized appraisal mapping at Forsyth County, NC. Thompson became President of Williams Stackhouse, Inc. in San Antonio in 1975, where he developed a first order surveying and GPS survey/mapping capability that was used to create and maintain military master plans for more than 100 bases. Later he formed his own company, Conversion Resources Corporation. In the mid-1990’s he was a founder of ATX Research, a predecessor of OnStar that provides telematics services for Mercedes, BMW, Rolls Royce and other fine cars today. He is a published magazine author and has served on the Board of Directors of the American Society of Photogrammetry and Remote Sensing as well as other companies. He has also served as a committee chair on both the National Emergency Number Association and the Association of Public Safety Communications Officials and holds a patent in GPS-based 9-1-1 services.

Larry Durbin, Chief Operations Officer

Larry Durbin was Manning NavComp’s first full-time Sales Director, and has grown and developed the same independent domestic, international, and vertical market-specific sales channels that the company continues to use today. Prior to his term at Manning NavComp, he managed a customer service and technical support team for Power Computing, Inc. He has been instrumental in the success of the company since joining with the company in 1998, consistently increasing sales while simultaneously controlling costs. He designed and implemented the proprietary Manning NavComp company-wide database system for tracking customer service, technical support, and sales activity and has developed many of the procedures used by company personnel. Durbin has a college background in electrical engineering and over 25 years of experience in management and customer service.

Lee Simmonds, Chief Development Engineer

Lee Simmonds signed on with Jeff in 1996 as lead developer. It wouldn’t be until a year later that the first general purpose GPS/AVL device would be manufactured, but he drove the development of the first truly major upgrade of the RASTRAC software and has continued to outdo himself in the years since. Simmonds’ unique experience in real-time control of signal processing and analysis systems at Raytheon E-Systems gives him QRC development expertise shared by few engineers in this country. He has applied those skills to almost every product in the RASTRAC suite, leaving a legacy of software applications that optimally exploit the computing platform while running for months without a hitch. His efforts position the company uniquely in the AVL middleware server industry, as a company that delivers software that works and keeps working. Simmonds earned the Bachelor of Science degree in Computer Engineering, Mathematics and Computer Science in 1987 from the University of Minnesota.
