Chennai, Jan 28 (UNI) The countdown for tomorrow's historic GSLV-F15/NVS-02 Mission,
marking ISRO's 100th Launch from the spaceport of Sriharikota, will begin shortly.
NVS-02 is Navigation Satellite and second in the series of NavIC constellation.
An official announcement from ISRO on the commencement of countdown is awaited as
the stage is set for the to be held from the Second Launch Pad (SLP) at 0623 hrs tomorrow
morning.
The Countdown, during which propellant filling operations will be carried out in the three
stage vehicle, including the indigenous cryogenic third stage, will begin after the Launch
Authorisation Boardd (LAB) and Mission Readiness Review Committee gives the nod.
ISRO posted in X "Be part of history as GSLV-F15 takes flight with NVS-02."
"Standing tall and ready for the skies! Here’s the mighty GSLV-F15 all set to launch the
NVS-02 satellite", it said, sharing photogrpahs of the GSLV rocket docked majestically
at the SLP.
"'GSLV-F15 integration complete! Take a sneak peek at the incredible teamwork behind
this mission: Join us as we unlock new frontiers,' it said.
This launch will herald yet another significant milestone as it marked the100th mission for
ISRO from the spaceport of SDSC-SHAR, Sriharikota in Andhra Pradesh tomorrow morning.
"The 50.9 m tall three stage vehicle, with the indigenous cryogenic stage, and with a lift of mass
of 420.7 tonnes, carrying NVS-02 Navigation Satellite, will lift off from the Second Launch Pad
at 0623 hrs on January 29 morning", it said.
NVS-02 will provide Advanced India's Regional Navigation Capabilities as part of NavIC series.
NVS-02 is the second in the series of Navic satellites. Navigation with Indian Constellation (NavIC)
is India’s independent regional navigation satellite system designed to provide accurate Position,
Velocity and Timing (PVT) service to users in India as well as to region extending about 1500 km
beyond Indian land mass.
After a flight duration of 19 minutes, the 2,250 kg satellite will be injected into a Geosynchronous
Transfer Orbit (GTO) at an altitude of 320 km with a perigee of 170 km and an apogee of 36,577 km
with a inclination of 20.79 deg.
This would be the first mission for ISRO in 2025 New Year after the successful docking of two
spacecrafts on board the PSLV/Spadex mission when two SpadeX satellites Chaser and Target
were successfully docked in space on January 16 in the very first attempt, propelling India to
become the fourth country in the world to master the space docking technology after US, Russia
and China.
GSLV-F15 is the 17th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV) and the
11th flight with Indigenous Cryo stage.
"It is the 8th operational flight of GSLV with an indigenous Cryogenic stage and 100th Launch
from the India’s Spaceport Sriharikota. GSLV-F15 payload fairing is a metallic version with a
diameter of 3.4 meters", ISRO said.
