August 2015 Meeting Summary

The Southern California Section of the Institute of Navigation hosted a meeting on August 18, 2015 at the John Deere facility in Torrance, CA.  About 30 people were in attendance.  The speaker was Ron Hatch, and in a departure from our usual navigation topics, the topic was Einstein’s Theory of Relativity.

Abstract of Ron’s Talk

Ron has developed a further description of the basis for his challenge to the generally accepted Theories of Relativity (special and general).  In this description, he challenges a fundamental assumption underlying the use of the Lorentz Transformation in Einstein’s special theory, i.e. that all inertial frames are symmetrical.  He finds, by invoking the conservation of momentum between inertial frames, that Special Relativity as formulated by Einstein is wrong and by invoking the conservation of energy between inertial frames, that Einstein’s General Theory of Relativity is wrong.  Ron argues that an apparent mathematical symmetry masks a real physical asymmetry and concludes that Space-Time is an invalid physical concept and that the curvature of space is not the source of gravitational force but that it is due to a gradient in the density of the local ether.  He explains why the argument of some prominent physicists that the effects of solar gravitational potential upon GPS clocks is cancelled out by the acceleration of the earth toward the sun is incorrect, i.e. that the equivalence principle is incorrectly applied.  Ron will link his theories of gravitation and critiques of relativity to GNSS and explain the genesis of this latest analysis in the light of earlier work.

Biography of Ron Hatch 

Ron Hatch graduated from Seattle-Pacific University in 1962 with a degree in physics.  Ron worked at Boeing in Washington State during most of his time at Seattle Pacific.  After graduation he joined the Johns Hopkins Applied Physics Laboratory and worked on the original Transit navigation satellite system. He later joined several other members of that group at Magnavox, where he resumed his work on Transit, developing much of the theoretical literature for navigation satellites generally, as well as Transit, and going on to basic contributions to GNSS theory and practice. This included a very basic contribution, the Hatch Filter, which underlies the high precision applications of GNSS.  He has been awarded over 30 patents as inventor or co-inventor.  He was an early winner of the Kepler Award from the Institute of Navigation and has received many honors since, including service as the Chair of the Satellite Division and President of the Institute.  After a period as an independent consultant to Leica and other companies and government laboratories, Ron was a joint founder of NavCom Technology, later acquired by John Deere, from which he has recently retired, but for which he continues to consult on occasion. He is currently a member of the US Space Based PNT Advisory Board. Ron continues his basic research and publication in cosmology and is a prominent contributor to journals of physics which are generally outside the mainstream of academic publications.
