Reality - governed by six invariant fundamental constants

The Global Positioning System GPS has shown that the results of general relativity must be taken into account in today's practical metrology. Therefore, it is here proposed that on the one hand the nomenclature of general relativistic physics should be adapted to the usual metrological „language“, which on the other hand should be adapted to the requirements of general relativity. For this purpose, the primary elements to be used for the treatment of physical problems shall be physical units (instead of coordinates), which will be defined in accordance with the requirements of general relativistic, quantum and classic physics.
