INSAT-4B hit by power problem, affects some TV, telecom services

Bangalore, Jul 9 (PTI) The INSAT-4B communication
satellite has been hit by a "power supply anomaly" in one of
its two solar panels, partially affecting some television and
telecom services in India.
The snag in the dedicated TV and telecommunications
satellite launched by Ariane5 rocket from French Guyana in
March 2007 with an estimated mission life of 12 years has led
to switching off 50 per cent of the transponder capacity.
The three-tonne INSAT-4B carries a total of 24
communication transponders (12 Ku-Band and 12 C-Band).
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, Indian Space
Research Organisation(ISRO) said in a release here on Friday.
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
release said.
An expert team is studying the possibilities of partial
utilisation of some of the transponders that were switched
‘off ’and restoring services at the earliest, itsaid. PTI JD
