About Broadcasting Satellite "Yuri" (BS)

The BS (Yuri series), in response to future broadcasting needs, have been used in a variety of broadcasting experiments as experimental satellites for reception by individual.
The BS-2 (Yuri-2) were designed to solve problems with transmission in areas with poor reception and for developing the technology required for future broadcasting services of the BS-2, responding to growing broadcasting satellites.
The BS-3 were launched to replace the broadcasting serices of the BS-2, responding to growing broadcasting needs while developing technologies for more advanced broadcasting satellites. They are presently being used for broadcasting and test broadcasting with high-definition television.
BS-2a finished its programmed operation in April, 1989. BS-2b finished its programmed operation on October 24, 1991. BS-3a finished its programmed operation on April 20, 1998. Also, BS-3b finished its programmed operation on December 1, 1998.
