Ronald R. Hatch
Ron Hatch is an expert in the use of GPS for precision farming, as well as other applications. Currently a consultant to John Deere, he was formerly the Director of Navigation Systems Engineering and Principal and co-founder of NavCom Technology, Inc., a John Deere company. That company provides a commercially operated differential GPS augmentation service to the agriculture industry and other high accuracy users.
Throughout his 30-year career in satellite navigation systems with companies such as Boeing and Magnavox, Hatch has been noted for his innovative algorithm design for Satellite Navigation Systems. He has consulted for a number of companies and government agencies developing dual-frequency carrier-phase algorithms for landing aircraft, multipath mitigation techniques, carrier phase measurements for real time differential navigation at the centimeter level, algorithms and specifications for Local Area Augmentation System, high-performance GPS and communication receivers, and Kinematic DGPS. In addition to the Hatch-Filter Technique, Hatch has obtained numerous patents and written many technical papers involving innovative techniques for navigation and surveying using the TRANSIT and GPS navigation satellites, authored Escape From Einstein in which he challenges competing relativity and other theories, and contributed significantly to the advancement of satellite navigation.
In 1994, Hatch received the Johannes Kepler Award from the Institute of Navigation for sustained and significant contributions to satellite navigation.
