CS 2a (Sakura 2a) [NASDA]

CS 2a and 2b (Communications Satellite 2a and 2b), renamed Sakura 2A and 2B were the second generation of japanese communications satellites. They were used for public communications operations and for cooperative operations such as emergency transmissions during disasters and communications with distant Japanese islands. They were also instrumental in developing new communications technology.

CS-2a or Sakura 2A was launched by the National Space Development Agency of Japan (NASDA) on a N-2 Star-37E from the Tanegashima Space Center. It was a business communications satellite, placed in a geostationary orbit at 132 East. It was part of the establishment of domestic satellite telecommunications network mainly for natural disasters, emergencies and for remote islands submillimeter wavelength and microwavelength signals.

CS-2b or Sakura 2B was launched on a N-2 Star-37E by Japan. It provided a reserve satellite on the orbit of CS-2A.
