LONDON: The Indian Space Research Organisation (Isro) has postponed launch of fourth navigation satellite IRNSS-1D onboard PSLV-C27, following an anomaly identified in on of the telemetry transmitters of the satellite.
The satellite was originally scheduled for launch on March 9, 2015, from Satish Dhawan Space Centre, Sriharikota.
Isro, in an announcement, said, “During the integrated electrical checks of launch vehicle along with satellite after the closure of heat shield on March 3, 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,” it added.
It is one of the seven satellites under the Indian Regional Navigation Satellite System (IRNSS), an independent Indian Satellite based positioning system for critical national applications. The main objective of the constellation of satellites is to provide reliable position, navigation and timing services over India and its neighbourhood, to provide positioning services over Indian region with an absolute position accuracy of better than 20 metres.
Space segment consists of seven satellites, three satellites in geo-stationary (GEO) orbit and four satellites in geo-synchronous orbit (GSO) orbit with inclination of 29 degree to the equatorial plane.
