I know that the answer to the question "What was the earliest that the system could provide data for the Asia-Pacific region?" is in "The BeiDou-2 system began offering services for the Asia-Pacific region in December 2012. At this time, the system could provide positioning data between longitude 55°E to 180°E and from latitude 55°S to 55°N.". Can you tell me what it is?
December 2012
