L-00:03 11:59:00 12:59:00 Beginning of irreversible launch sequence (last possibility to state NO-GO for spacecraft)
L-00:00:30 12:01:45 13:01:45 Switch off of launch vehicle payload air conditioning system
L-00:00 12:02:15 13:02:15 Launch (End of Gyros Setting). This is the start time of the Rockot mission.
L+00:00:14 12:02:29 13:02:29 L0 – LIFT OFF – Rockot launch vehicle lifts off from launch pad at Plesetsk Cosmodrome
L+00:00:50 12:03:19 13:03:19 At a speed of 567 m/sec and altitude of 10.7 km, the Rockot vehicle experiences the point of maximum dynamic pressure
L+00:02:16 12:04:31 13:04:31 1st/2nd Stage separation – about 68 km altitude
L+00:03:04 12:05:18 13:05:18 Payload Fairing Jettison – The fairing is discarded at an altitude of about 125 km, as the vehicle is now well into space. Speed is now 3.6 km/sec.
L+00:05:19 12:07:34 13:07:34 2nd/3rd Stage separation – At 235.7 km altitude, the second stage separates
L+00:05:25 12:07:40 13:07:40 First Ignition Upper Stage – Breeze-KM upper stage carrying Swarm starts first engine burn
L+00:14:41 12:16:56 13:16:56 End of Upper Stage first burn – Breeze-KM end of first burn. Altitude is now about 250 km at a speed of 7.8 km/sec. Begin 61 minute coast phase.
L+01:15:54 13:18:09 14:18:09 Second Ignition Upper Stage – Breeze-KM starts second engine burn lasting just 16 seconds
L+01:16:10 13:18:26 14:18:26 Cut-off Upper Stage – Breeze-KM shut down; injection into orbit at about 490 km
L+01:31:32 13:33:47 14:33:47 Spacecraft-Upper Stage separation – The Swarm trio separate from the breeze-KM upper stage; spacecraft start a 240-second automated sequence to switch on critical systems including transmitters and attitude control
L+01:31:36 13:33:51 14:33:51 First Acquisition of Signal (AOS) of Swarm A and B via Kiruna station, Sweden
L+01:35:28 13:37:43 14:37:43 First AOS of Swarm C via Svalbard station, Norway
L+01:43:05 13:45:20 14:45:20 Start of Upper Stage de-orbit Burn 1 – First Breeze deorbit burn
L+01:43:15 13:45:3 0 14:45:30 End of Upper Stage de-orbit Burn 1
L+02:30:00 14:32:15 15:32:15 Start of Upper Stage de-orbit Burn 2 – Second Breeze deorbit burn
