The ISRO will launch the IRNSS 1-D satellite through the PSLV C-27 (XL) vehicle from the Satish Dhawan Space Centre at Sriharikota on Saturday, helping India begin the operation of an indigenous regional navigation satellite system.
“With the functioning of IRNSS 1-D in orbit, proof-of-concept of an independent regional navigation satellite system over India can be established,” the ISRO said.
The 1,425-kg IRNSS 1-D is the fourth in a series of seven satellites that, along with ground stations, form the Indian Regional Navigation Satellite System (IRNSS).
The IRNSS 1-D launch, scheduled for 5.19 p.m., will help the country begin operations partially, and the system will become efficient once all seven satellites are positioned in space, an ISRO official said. A common service and restricted service will be provided after the seventh satellite is launched. Though the navigation system is indigenous, it cannot be compared with the U.S. Global Positioning System (GPS), since the IRNSS will cover areas only in South Asia.
“The countdown is proceeding smoothly, and the vehicle is ready at the second launch pad,” the official said.
