Adequate Coordinate System for Space Navigation — •Hans-Otto Carmesin — Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen — Studienseminar Stade, Bahnhofstr. 5, 21682 Stade — Gymnasium 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).
Here, that problem is solved:
(1) A measurement procedure is presented.
(2) For each Point P, an ACS and its velocity vACS,CS→ relative to an arbitrary coordinate system (CS) are deduced.
(3) The ACS is confirmed by an observation at Earth and at space.
(4) The universal zero of the fractional kinematic time difference δ tkin,fractional is derived.
(5) For each Point P, the fractional kinematic time difference δ tkin,fractional is derived and predicted.
