During the final checks on INSAT-3A, which was scheduled for launch between 04.19 am and 05.00 am IST this morning (April 9, 2003), it was observed that the signal strength from one of the two telemetry transmitters was less than nominal. This anomaly could not be resolved before the close of launch window and hence the launch was called off for the day.

The revised date of launch will be announced soon.
