N-Star-A
1995-044A
The N-STAR a satellite is an FS-1300 class Space Systems/Loral satellite built for Nippon Telephone and Telegraph (NTT) of Japan.
N-STAR a was launched on the V77 flight of Ariane, using an Ariane 44P with an H-10 III third stage and the 01 fairing. The launch profile used a standard geostationary transfer orbit. N-STAR a is to replace the CS-3 satellite at 132E. The satellite was damaged during transportation from California to Guiane, and several weeks were needed for repairs.
The N-STAR a satellite has a launch mass of 3410 kg, a dry mass of 1617 kg, and a BOL mass of 2057 kg. The 3-axis stabilized satellite has a solar panel span of 27.3m, and a bus size of 2.4 x 2.2 x 2.2 m. Height is 6.3 m including the payload mast. The large composite antenna was 4.5 x 2.6 m in size. Mass of the third stage in orbit with the VEB is 2065 kg at orbit insertion, or 1770 kg after fuel depletion (1240 kg H-10-3, 530 kg VEB).

CBERS-3
2003-049A
The second China-Brazil Earth Resources Satellite, CBERS-2 was built at INPE in Brazil. It was launched from China in Oct 2003 on a CZ-4B and called ZY-1 No. 2 by the Chinese, although they also refer to it as
\uni{ 中巴地球资源卫星02星 }{ }
(Zhongba diqiu ziyuan weixing 02 xing, Brazil Earth Resources Satellite 02). Mass was 1550 kg.\imps{3.0}{images/03049A}
