Earlier, a glitch in one of the electro-hydraulic control actuators in the second stage of PSLV-C22 had forced ISRO to postpone the launch of IRNSS-1A on June 12 by a fortnight.
As per the source, the satellite is intended to provide terrestrial, aerial and marine navigation services and help in disaster management. The system is similar to the global satellite positioning (GPS) of the US and other countries.
Isro official Deviprasad Karnik, said: “We have overcome the obstacle for launch of PSLV-C22, now the vehicle is assembled and global checks have been completed. The rehearsal is on to launch the 1380 kg IRNSS-1A satellite, the first navigational satellite on July 1. By launching seven satellites in the constellation of IRNSS, India can reduce its dependency on other countries such as the US and Russia for GPS based services.”
MC Dathan, Director, LPSC, said: “The launch authorisation board meeting and final mission rehearsal was completed on Thursday and propellant filling operation is on. Filling propellants will be completed and by July 1 afternoon it will be ready. This XL version of PSLV is slightly longer than the original vehicle with six extended solid strapons.”
As per the source, officials of the Isro establishments are equally anxious about the GSLV D-5 mission to launch the communication satellite GSAT -14 on August 6, from the second launch pad at Sriharikota where the vehicle integration is in progress.
