Brasilsat B1

 1994-049B


Brasilsat B1 was the first widebody HS-376 satellite. The HS-376W featured an R-4D-12 liquid apogee engine. It was launched in Aug 1994 on an Ariane together with Turksat 1B.

Size was 3.64m dia 3.7m high stowed, 8.4m deployed. Mass is 1765 kg launch, 1052 kg BOL, 942 kg dry.

After the creation of Star One in 2000, the satellite was renamed Star One B1.

GSAT-4

 2010-F01


Launch to 83E. Carries one experimental nav transponder, as well as comms payload of a Ka-band regenerative bent-pipe transponder.

GAGAN is a GPS augmentation system (and 'Gagan' is Hindi for 'sky').

Satellite was Box + 2 panels I-2K bus 2220 kg full 1063 kg dry. SIze 2.4 x 1.6 x 1.5m with ? span.

Launch by GSLV-D3 from SHAR using CUS upper stage with ISRO Cryogenic Engine. GSLV Mk II first flight, with enlarged 8.7m long 4m dia fairing. The CUS has the main ICE of 69.5 kN and two verniers of 2 kN each. Prop flow rate is 16.6 kg/s. The stage 3 turbopump failed after 1 second and the mission failed to reach an appreciable orbit.

Globalstar 1

 1998-008A


The first four satellites were launched by a new Delta configuration, the 7420 with only 4 strapon boosters. A dispenser on the second stage carried two satellites in its lower deck and two on its upper deck.

The Delta depletion burn placed the second stage in an orbit very close to that planned, with a perigee of only 244 km.

Palapa D

 2009-046A


PT Indosat Tbk satellite, Thales Alenia Space (TAS-F) Spacebus 4000B3 with 24 C-band, 11 extended C-band and 5 Ku-band. Launch mass 4100 kg. To replace Palapa C2. Launch by CZ-3B.

Satelindo was acquired by Indosat in 2003; Indosat became the Palapa operator.

The CZ-3B third stage failed during its second burn leaving Palapa D in a low transfer orbit. The second burn went its planned full duration but one of the two third stage engines delivered lower than expected thrust. The payload was able to achieve operational orbit.
