Bangalore: The INSAT-4B communication

its two solar panels which has led to switching off 50 per
cent of the transponder capacity.
Due to a power supply anomaly in one of its two solar
panels, there has been a partial non-availability of services
on India`s INSAT-4B communication satellite, ISRO said in a
release here today.
On the night of July 7, the satellite experienced a
power supply glitch which led to switching off 50 per cent of
the transponder capacity (6 Ku and 6 C-Band transponders), the

partial utilisation of some of the transponders that were
switched off and restoring services at the earliest, it said.
