Sriharikota (AP), Jun 22: Setting a record in its space programme, India today successfully launched 20 satellites, including its earth observation Cartosat-2 series, in a single mission on board ISRO's workhorse PSLV-C34 from the spaceport here.

In a precision launch, PSLV-C34 took off from the second launch pad of Satish Dhawan Space Centre here, about 110 km from Chennai at 9.26 AM and placed the Cartosat-2 Series and 19 others in the designated polar Sun Synchronous Orbit (SSO) about 30 minutes later in clear skies.

The 727.5 kg Cartosat-2 series satellite will provide regular remote sensing services with its panchromatic and multispectral cameras and its imagery will be of multiple use.

Of the 19-satellites, 12 are earth imaging "Dove satellites" of USA and another American satellite. The rest are from Canada (two) and one each from Germany and Indonesia.

Two academic satellites are from Sathyabama University (Sathyabamasat) in Chennai and from College of Engineering (Swayam) at Pune.

Use of Cartosat 2 includes cartographic, urban and rural applications, coastal land use and regulation, utility management like road network monitoring and water distribution.

Also, creation of land use maps, precision study,change detection to bring out geographical and man-made features and various other Land Information System and Geographical Information System applications can be done. It is similar to the earlier Cartosat-2, 2A and 2B.

Prime Minister Narendra Modi congratulated ISRO and described today's launch as a "monumental" accomplishment.

"20 satellites in a go! @ isro continues to break new barriers. hearty congratulations to our scientists on the monumental accomplishment', he said on Twitter.

ISRO Chairman A S Kiran Kumar congratulated his team for the successful launch 'in a record time' and said "PSLV C-34 has done its job."

"We have the current generation of earth observation satellite of Cartosat 2 series," he said, adding ISRO had done a "wonderful job".

P Kunhikrishnan, Director, SDSC-SHAR, said that it was a major accomplishment by PSLV in its 35th consecutive successful mission.

"PSLV has become a success symbol for ISRO and India. ISRO is adopting more and more professionalism," he said.

D Jayakumar, Mission Director,described today's launch as a major landmark and said that the vehicle performance was "exceedingly well."

With today's launch of 20 satellites, PSLV beat its 2008 record when it placed in orbit 10 satellites in a single launch into various Low Earth Orbits.

This is the 14th flight of PSLV in "XL" configuration known for its capacity to carry more load which uses 'solid strap-on motors'.

The total weight of all the 20 satellites carried onboard PSLV-C34 is about 1288 kg.

India has 11 operational earth observation satellites, including RESOURCESAT-1 and 2, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2 are in orbit.

Beginning in 1988, ISRO had launched many remote sensing satellites (for earth observation) and the data are for varied use including agriculture, water and ocean resources besides disaster management.

The Kozhikode International Airport located at Karipur is not safe for the landing of flights in rainy season, according to an air-safety expert, who had warned the aviation ministry and the civil aviation regulator about this in 2011. 

The warning was particularly about the dangers of permitting passenger aircraft to land on runway 10 of the airport during rains and unfavourable wind conditions. 

Nine years later, on August 7, 2020, the warning became a reality when an Air India Express pilots landed in tailwind conditions and the aircraft overshot the tabletop runway to drop off the end and crash.

 “An aircraft landing on runway 10 in tailwind will experience poor braking action due to heavy rubber deposits … All such flights … are endangering the lives of all on board,’’ said Capt Mohan Ranganathan, in a letter sent on June 17, 2011 to then director general of civil aviation Bharat Bhushan and Nasim Zaidi, chairman of a civil aviation safety advisory committee, which was formed after the May 2010 Mangaluru air crash which killed 158 people.

“My warning issued after the Mangaluru crash was ignored. It is a table-top runway with a down slope. The buffer zone at the end of the runway is inadequate,” Capt Ranganathan said. Given the topography, he pointed out, the airport should have a buffer of 240m at the end of the runway, but it only has 90m (which the DGCA had approved). “Moreover, the space on either side of the runway is only 75m instead of the mandatory 100m,” he added.

Capt Ranganathan said there is no guideline for operations on a table-top runway when it is raining. “Runway 10 approach should not be permitted in view of the lack of runway end safety area (RESA) and the terrain beyond the end of the runway. RESA of 240m should be immediately introduced and runway length has to be reduced to make the operations safe,” his letter said.

If an aircraft is unable to stop within the runway, there is no RESA beyond the end. The ILS localiser antenna is housed on a concrete structure and the area beyond is a steep slope. “The Air India Express accident in Mangalore should have alerted AAI to make the runway conditions safe. We have brought up the issue of RESA during the initial Casac-sub group meetings. We had specifically mentioned that the declared distances for both runways have to be reduced in order to comply with ICAO Annex 14 requirement,” Capt Ranganathan said.

He said the condition of the runway strip was known to DGCA teams that have been conducting inspection and safety assessments. “Have they considered the danger involved? Did the DGCA or the airlines lay down any operational restrictions or special procedures?”

The letter also refers to Approach and Landing Accident Reduction (ALAR) training, which is supposed to be mandatory before every monsoon, but airlines don’t follow it, he said. “70% of accidents take place during approach and landing and that is why this training is essential,” he added.
