Regional ATOVS Retransmission Services (RARS)

RARS implementation status

The evolution of the RARS coverage is shown in the following Network Implementation diagrams (click thumbnails to view the full size images):

	The global RARS network at the beginning of 2009
	The anticipated global RARS network by the end of 2009
	The anticipated global RARS network by the end of 2010
It should be noted that the maps showing the "anticipated" networks reflect only what is firmly planned. Further expansions are under active consideration (to achieve the goal of near global coverage). The maps will be updated to reflect these as soon as firm plans are in place.
