Herring (born 17 July 1955 in Cooroy, Queensland, Australia) is a geophysicist, known for developing and applying systems of space geodesy to high-precision geophysical measurements and geodynamic research.
[4] His Ph.D. thesis entitled The precision and accuracy of intercontinental distance determinations using radio interferometry was supervised by Irwin I.
[2] As part of a four-member team, Herring used VLBI data to publish an empirical nutation model,[9][10] which was used by the International Earth Rotation Service for a considerable time.
[2][11][12] Herring was among the pioneers who used the global positioning system (GPS) for better understanding of geodynamics, including highly accurate measurements of variations of the rate of Earth's rotation.
[14] In earthquake research,[15] he has been a member of teams that used GPS and VLBI data to determine velocity fields for crustal deformations in southern and central California.
GAMIT accepts phase data and returns estimates of "three-dimensional relative positions of ground stations and satellite orbits, atmospheric zenith delays, and Earth orientation parameters."
