MissionCommercial: Communication
Geostationary orbit on:
Perigee / Apogee 35767 x 35806km
Eccentricity 4.63E-04
Inclination 3.32 deg
Period 1436.12 min

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

A power regulator failed resulting in only 80% of eclipse power available.
