L40H Strap-on Shutdown |
The GSLV's four strap-on boosters consume their propellant and shut down their Vikas engines at T+plus 2 minutes, 29 seconds. The booster shutdown comes shortly after the rocket's solid-fueled core stage burns out. |

T+16:55 |
Third Stage Shutdown |
The third stage engine shuts down after reaching an orbit with a low point of about 180 kilometers, or 111 miles, a high point of 35,975 kilometers, or 22,353 miles, and an inclination of 19.3 degrees. |
