Fundamental Geodetic Parameters 1999

Abstract

AbstractThe present (2000) set of primary “constants” and “current best estimates” is being reviewed. The emphasis within IUGG is on the consideration and numerical evaluation of temporal changes of relevant parameters. The accuracy of many parameters has been substantially improved, but many numerical values did not change significantly. Therefore, to avoid confusion IUGG/IAG are reluctant in introducing new official parameter sets but keep “current best estimates” up-to-date.
