This was ISRO's maiden launch of 2018, while also being the first launch after the unsuccessful launch of the IRNSS-1H satellite in August 2017, when the PSLV rocket's heat shield separation failed to take place.
The weather observation PSLV-C40 / Cartosat-2 Series Satellite and 29 others will be inserted into a 505-kilometer sun-synchronous orbit following seventeen and a half minutes since its takeoff. The opening mission of 2018 was considered crucial for ISRO as the previous PSLV launch came as a setback to scientists as the backup navigation satellite IRNSS-1H could not be placed in orbit following a snag in the final leg of the PSLV-C39 mission in August a year ago.
India on Friday deployed a remote sensing Cartosat and 30 other satellites, including 28 from six nations into the earth's orbit after a copybook launch from its spaceport here.
The co-passenger satellites comprise one microsatellite and one nanosatellite from India as well as three microsatellites and 25 nanosatellites from Canada, Finland, France, Republic of Korea, the United Kingdom and the United States. It will also mark the PSLV's 42nd flight that will lift off from the Satish Dhawan Space Centre. "Out of the 31 Satellites, 28 belonging to 6 other countries are carried by today's launch", the Prime Minister said. It should be noted that this is the longest missile launch that ISRO has handled, as it will take 2 hours 21 minutes to to reach the space and the two orbits.
The satellite will be launched shortly.
The satellites would be placed in their intended different orbits finally after manoeuvres from the space agency's Master Control Facility (MCF) at Hassan in Karnataka, about 180 km from Bengaluru.
India will use its latest satellites for better border surveillance and obtaining high resolution images of the earth. "We are coming to the launch pad after four months".
