India: A glitch in one of the electro-hydraulic control actuators in the second stage of the launch vehicle has forced the Indian Space Research Organisation (ISRO) to postpone the launch of India’s maiden navigation satellite — IRNSS-1A — by a fortnight.
IRNSS-1A, the first in the series of Indian Regional Navigation Satellite System (IRNSS) constellation, was scheduled to be launched on June 12 aboard the PSLV-C22.
“The satellite has gone through all electrical checks and is ready for propellant-filling. However, during the electrical checks of the launch vehicle, an anomaly was discovered in one of the electro-hydraulic control actuators in the second stage. It has been decided to replace this actuator,” ISRO said in an official release.
Stating that it would take about two weeks for the replacement of the actuator, officials said that the launch has now been rescheduled to June 26 from Sriharikota, near Chennai.
