T-00:00 PS1 Ignition
The PSLV's solid-fueled first stage motor ignites when the countdown clock reaches zero.
T+01:51 First Stage Separation/Second Stage Ignition
Flying at an altitude of nearly 53 kilometers, or about 33 miles, the PSLV's solid-fueled first stage burns out and separates after consuming more than 300,000 pounds of propellant. The PSLV's Vikas second stage engine ignites less than a second later.
T+01:57 Closed-loop Guidance
The PSLV initiates closed-loop guidance.
T+03:07 Payload Fairing Jettison
The 3.2-meter, or 10.5-foot, diameter aluminum payload fairing jettisons once the PSLV flys above the dense lower atmosphere, exposing the Spot 7 satellite to space.
T+04:22 Second Stage Separation
The PSLV's Vikas engine shuts down and the second stage separates at the conclusion of its burn at an altitude of 219 kilometers, or about 136 miles.
T+04:23 Third Stage Ignition
The PSLV's third stage solid-fueled motor begins a 112-second burn.
T+08:41 Third Stage Separation
The PSLV's third stage separates from the fourth stage, beginning a 10-second coast period before the fourth stage fires to complete the powered phase of the launch.
T+08:51 Fourth Stage Ignition
The PSLV's fourth stage, powered by two hydrazine-fueled engines, ignites to propel the Spot 7 payload into a near-circular 656-kilometer (407-mile) orbit. The burn will last about 8 minutes, 25 seconds.
T+17:17 Fourth Stage Shutdown
The fourth stage shuts down after achieving a near-circular orbit with a perigee of 655.1 kilometers (407.1 miles), an apogee of 657.7 kilometers (408.7 miles) and an inclination of 98.23 degrees.
T+17:54 Spot 7 Separation
The PSLV fourth stage deploys the 714-kilogram (1,574-pound) Spot 7 spacecraft for Airbus Defence and Space.
T+18:34 AISat Separation
The PSLV fourth stage deploys the 14-kilogram (30.8-pound) ship-tracking AISat satellite for DLR, the German Aerospace Centre.
T+19:04 CanX-4 Separation
The PSLV fourth stage deploys the 15-kilogram (33.1-pound) CanX-4 technology demonstration satellite for the University of Toronto Institute for Aerospace Studies Space Flight Laboratory.
T+19:34 CanX-5 Separation
The PSLV fourth stage deploys the 15-kilogram (33.1-pound) CanX-5 technology demonstration satellite for the University of Toronto Institute for Aerospace Studies Space Flight Laboratory.
T+19:59 VELOX 1 Separation
The PSLV fourth stage deploys the 4.5 kilogram (9.9-pound) VELOX 1 satellite for Nanyang Technical University of Singapore.
