Astronomical relativistic reference systems with multipolar expansion: the global one

摘要: With rapid development of techniques for astronomical observations, the precision measurements has been significantly increasing. Theories relativistic reference systems, which are foundation processing and interpreting these data now in future, may require extensions to satisfy needs trends. Besides building a framework compatible with alternative theories gravity pursuit higher order post-Newtonian approximation, it will also be necessary make first multipole moments celestial bodies explicitly expressed systems. This bring some convenience into modeling observations experiments easier distinguish different contributions measurements. As step, global solar system is multipolarly expanded mass spin shown metric describes coordinates system. The full expression given.
