The Launch Authorisation Board (LAB) for Polar Satellite Launch Vehicle (PSLV-C19)/Radar Imaging Satellite (RISAT-1) mission, which met on April 21, 2012 at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota has cleared the launch of PSLV-C19/RISAT-1 mission at 05:47 hrs (IST) on Thursday, April 26, 2012.
The 71-hour countdown commenced at 06:47 hours today (April 23, 2012). During the Countdown, propellant-filling operations of the liquid propellant second stage (PS2) and fourth stage (PS4) of the launch vehicle will be carried out. Besides, mandatory checks on the launch vehicle and spacecraft will be carried out. Also, charging of batteries and pressurisation of propellant tanks onboard the satellite will be performed. Readiness of various ground systems such as tracking radar systems and communication networks will also be checked.
PSLV-C19 will inject RISAT-1 satellite into an orbit of 480 km altitude at an inclination of 97.552o. The satellite will be put in its final orbital configuration at 536 km altitude using thrusters onboard the satellite.
