The launch of India’s fourth Navigation Satellite IRNSS-1D onboard PSLV-C27 was originally scheduled for March 09, 2015 from Satish Dhawan Space Centre, Sriharikota. During the integrated electrical checks of Launch Vehicle along with Satellite after the closure of heat shield on March 03, 2015, an anomaly was observed in one of the telemetry transmitters of the Satellite. In order to resolve the technical anomaly through further test, simulation and analysis, the launch of PSLV-C27 with IRNSS-1D has been postponed.
