1991-060A
The Broadcasting Satellite 3b (BS-3b) was launched in Aug 1991 by NASDA. After on-orbit checkout it was delivered to TCSJ.
The H-I second stage ended up in an elliptical orbit with perigee over the equator; although the press kit does not mention a second stage restart, it seems likely that this occurred.
The GE 3000 bus was 1.3 x 1.6 x 1.6 m in size, 3.2 m high once the antennae were deployed with a 15 m solar panel span. Launch mass was 1115 kg, 550 kg BOL.
