Launch of IRNSS-1D Delayed Due to Technical Problem

The Indian Space Research Organization (ISRO) has postponed launch of the fourth Indian Regional Navigation Satellite System spacecraft (IRNSS-1D), originally scheduled for March 9, due to an anomaly. During integrated electrical checks of the  PSLV-C27 launch vehicle and IRNSS-1D after the closure of heat shield on March 3, an anomaly was observed in one of the telemetry transmitters of the satellite.

In order to resolve the technical problem through further test, simulation, and analysis, the launch of PSLV-C27 from Satish Dhawan Space Centre, Sriharikota, India, has been postponed. Seven satellites will comprise the full constellation, which is expected to be completed this year.
