Cakrawarta 1
On September 1997, the Indonesian President renamed the satellite. It
was previously called Indostar 1
Up to 4 small satellites have been ordered: Indostar 2 at 115°E and
Indostar 3 at 106°E (or all four satellite colocated at 107.5 and
119°E) The full project (satellite, launch, ground station, etc) is worth
$175 million
Originally designed for TV and DAB, the satellite was modified to provide only
TV capacity in S-band (this band was selected to face high attenuation caused
by the rain).
A power regulator failed resulting in only 80% of eclipse power available.
Insurance paid $25 million.
