Amidst news of Tata(Sky adding new channels on their existing satellite Insat 4A at 83.0°E, they had a ray of hope with the launch of GSat12 in July 2011.
GSat12 is co-located with Insat 4A at 83.0°E. So it would have been a win-win situation without the need for re-aligning millions of dish antennas.
However much to the disappointment of Tata(Sky, this GSat12 has only Extended C-band transponders and not a single Ku-band transponder.
Over-utilization of Insat 4A by increasing beams may lead to its decreased service life or irreversible failure.
