SupremeSAT has said the comsat will be placed in a geostationary orbit at 87.5East longitude, after being taken to space by a Long March 3B/E launch vehicle.
It will have a footprint covering parts of the Middle East, South & Central Asia and also Australia.
The 5,100 kilogram 'SB 4000' series satellite with 36 transponders was built by Thales Alenia Space of France.
"SB 4000 series has a successful flight heritage, hence it's a very stable and reliable space platform," SupremeSAT says in its website.
The satellite is a joint venture between Sri Lanka's Supreme group and China's state-run Greatwall Industry Corporation and is backed by Rohitha Rajapaksa, a son of President Mahinda Rajapaksa.
