[FONT=Verdana, Arial, Helvetica, sans-serif]NGALORE: In a rare development, a power supply glitch on Indian Space Research Orgnisation's (Isro) INSAT-4B has resulted in partial disruption of the services of two direct-to-home (DTH) operators, a few regional television channels and telecom services.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Sun Direct and DD Direct Plus use the Ku-band transponders of Insat-4B.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]There was a power supply anomaly in one of the two solar panels that supply power to the satellite, said an Isro official.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]The INSAT-4B carries a total of 24 communication transponders (12 Ku-Band and 12 C-Band) and has been in operation since March 2007.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Isro admitted on the night of 7 July INSAT-4B experienced a power supply glitch which led to switching 'off' of 50 per cent of the transponder capacity (6 Ku and 6 C-Band transponders). [/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]An expert team is studying the possibilities of partial utilisation of some of the transponders that were switched off and restoring the services at the earliest. [/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif][/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]"We are looking at the problem and are trying to solve it over the next week. In case that does not happen, we will consider other arrangements," said a source at Isro.[/FONT]
