BSAT Satellite Details
The BSAT fleet has an extensive history, with the first satellite launched in 1994. The current fleet of Broadcasting Satellite System Corporation as of August 2020 is composed of five spacecraft.
BSAT-1a was an HS-376 based satellite with 4 active plus 4 spares Ku-band transponders, launched on 16 April 1997 aboard an Ariane 44LP. It was successfully launched along Thaicom 3.
The current satellites in the BSAT fleet are BSAT-3a, BSAT-3b, BSAT-3c, BSAT-4a, and BSAT-4b. Here's a brief overview of each:
BSAT-4b
BSAT-4b is the second satellite of the fourth generation BSAT, built by Maxar Technologies on its SSL 1300 platform. It has 24 Ku-band transponders and a mass of around 3,530 kilograms (7,780 lb).
BSAT-4b was launched aboard an Ariane 5 ECA on 15 August 2020. This satellite is part of a long history of broadcasting satellites operated by B-SAT, a unique operator of broadcasting satellites in the 12GHz BSS band in Japan.
The B-SAT fleet has an extensive history, with satellites like BSAT-3a, BSAT-3b, and BSAT-3c serving as part of the company's current operations. These satellites, along with BSAT-4a and BSAT-4b, provide high-quality, reliable direct-to-home services throughout Japan.
Here's a brief overview of the BSAT-4 series:
