System international reference precipitation with the acronym IC audio (ICRS) is a way to create frame of reference for coordinates in space. that for the same storage among the international organizations proposed by the International Astronomical accepted fact. This method is based on the location of the equator and Equinox at the year 2000 is created. Now to determine the coordinates to this method, view, radio, season, Galaxy, distant used. This system coordinates space fixed and the coordinates of the center of mass. Due to the fact that this system fixed in space. it can be used to display the location and displacement of celestial bodies to good use. This system is naked.

your CD audio set of the rules is that a system of coordinates with high precision with use of the Tensor metric, etc. to find a solution and keep the axis moving using a list of celestial objects and the exact coordinates of the model, and the standard algorithms which convert the coordinates to other coordinates makes it easy to. defines. The difference between system reference and frame of reference in this case must be considered to be exposed. Video from a local that the utility space in the move is the preparation. then the image with the use of tools, find pattern are examined and the stars available in the image based on the shine with the source of the stars are compared. Then the location of the utility space with very high accuracy comes to hand. Source, used in the system of the two bases is different. One 608 Manie radio, he, El, is that periodically the location, by the international service of rotation of the Earth and the system, reference to be updated. Another map is a satellite developed. Error created by the year 2010 in the source about 20 H is that for the brightest stars have been measured. The European Space Agency and other organizations space to use for the public from this system of algorithms to programming languages, have created. Those errors and optimize the required resources, both in software terms.
