BSAT-1a was a Japanese communications satellite operated by the Broadcasting Satellite System Corporation. Launched in 1997 it was operated in geostationary orbit at a longitude of 110° east until its decommissioning on 3 August 2010.[3] The spacecraft has the International Designator 1997-016B and the catalogue number 24769.[5]

Constructed by Hughes, BSAT-1a was built around the HS-376 satellite bus. It had a mass at launch of 723.0 kilograms (1,593.9 lb) and was designed for ten years of service.[6] The spacecraft's communications payload consisted of eight ku-band transponders; four primary and four backup; which were used for analogue television broadcasting.[6][1]

The spacecraft was launched by Arianespace, atop a Ariane 44LP, flight number V95, flying from ELA-2 at Kourou. The launch took place at 23:08:44 UTC on 16 April 1997, successfully placing BSAT-1a and Thaicom 3 into a geostationary transfer orbit.[2] The satellite subsequently manoeuvred into its operational geostationary orbit by means of its Star 30BP apogee motor.
