there are the asian sattelite, vietnam sattelite, .... can anybody explain me, what that mean? Thanks!
AFAIK, they're basically lower-tier tournaments as opposed to IBF star-ranked tournaments (e.g., World Championship, All England, China/Denmark/Malaysia/US/Indonesia Open, etc.).
Satellite tournaments are 'A grade' IBF events. A victory in an A grade event is worth 1800 world ranking points. In Grand Prix events, victories are worth : 2400 points for 1* 3000 points for 2* 3600 points for 3* 4200 points for 4* 4800 points for 5* 5400 points for 6* 6000 points for 7* Hope this helps...
Very unlikely. But Korea, Malaysia, Singapore, Indonesia, and Thailand do sometimes send its second or even third team to a satelitte tournament. It's an experience for youngsters before they eventually move up the ranks to compete in the 1 to 3* events.
