Correction data of a virtual reference station is produced through RAAS, a regional area augmentation system used by the DGNSS Central Office, and transmitted to the broadcasting stations. Four broadcasting stations (KBS, MBC, SBS and YTN) receive the correction data to be broadcast to users in DMB format. It is currently under pilot service operation in the Seoul National Capital Area at present.
