First commercial Chinese launch; Stationed at 105 deg E; formerly Westar 6 (retrieved by STS-51A and refurbished). Fixed-satellite telecommunication services and transmission of television signals. Operational life about 10 years. Orbital position 105.5E. Owner/operator: Asia Satellite Telecommunications Co, Ltd. 23-24/F, East Exchange Tower, 38-40 Leighton Rd, Hong K ong. Telex 68345 ASAT HX Fax 852 576 4111.

TV; 24 C-band and 9 Ku-band transponders. Stationed at 100.5 deg E.

The spacecraft was left in a high inclination useless orbit by a failure of the DM-3 stage and became an insurance writeoff. Two trips around the Moon to remove the inclination under its new owner (Hughes) saw it back into very limited service (as HGS-1) by August 1998 over the Indian Ocean and available for sale at bargain rates.

A replacement for Asiasat 3, placed in the wrong orbit by a Proton launch in 1997, Asiasat 3S carried C and Ku band transponders. The Blok DM3 upper stage placed it a 9,677 km x 35,967 km x 13.1 deg geosynchronous transfer orbit. Asiasat's on-board R4D apogee engine was to be used to raise perigee to geostationary altitude. Mass in transfer orbit was 3,463 kg, down to 2,500 kg after insertion in geostationary orbit. Stationed at 105 deg E.
