Adequate Coordinate System for Space Navigation and Relativity — •Hans-Otto Carmesin — Univ. Bremen, FB 1, Postfach 330440, 28334 Bremen — Studienseminar Stade, Bahnhofstr. 5, 21682 Stade — Gymn. Athenaeum, Harsefelder Straße 40, 21680 Stade
The International Astronomical Union (IAU) realized, that the coordinate systems of relativity theory are insufficient for space navigation. Therefore, the IAU proclaimed the problem of finding an adequate coordinate system (ACS) for space navigation and relativity.
Here, that problem is solved:
(1) A measurement procedure is presented. (2) For each Point P in the universe, an ACS is derived, and its velocity vACS,CS→ relative to an arbitrary coordinate system (CS) is derived. (3) The ACS is confirmed by an observation at Earth, using two atomic clocks, one at the PTB and one at the MPQ (Max Planck Institute for Quantum Optics). (4) The universal zero of the fractional kinematic time difference δ tkin,fractional is derived. (5) For each Point P, δ tkin,fractional is derived. This is confirmed by observation data at Galileo satellites. As a consequence, the precision of clocks onboard spacecrafts can be improved. This can provide improvements in space navigation, remote sensing or geoinformatics.
