GStar-2, Brasilsat-A2

The GStar satellites form the Ku-band component of GTE's satellite fleet. The spacecraft were based on RCA's (later GE Astro's) AS-3000 three-axis stabilized bus. They featured a communication payload consisting of 16 active Ku-band transponders with 5 more as a reserve.

Embratel of Brazil in August 1982 contracted with Canada's Spar Aerospace, Ltd., teaming with Hughes, for its Brasilsat A series of HS-376 satellites. The satellites feature 24 C-band transmitters with an additional 6 spares.
