The team was seen beaming and congratulating each other after the range controller announced the successful separation of different stages, especially the heat shield, two minutes and 31 seconds after take-off and deployment of all the satellites except India's Microsat, which was injected into a lower obit an hour later.
The Indian Space Research Organisation (ISRO) had suffered a setback after the failure of the earlier PSLV-C39 mission in August a year ago.
After the successful launch of PSLV-C40 on Friday, scientists and directors of Isro units here, including Vikram Sarabhai Space Centre (VSSC) and Liquid Propulsion Systems Centre (LPSC), are back.
ISRO's launch vehicle Polar Satellite Launch Vehicle (PSLV) C-40 will carry the satellites from Satish Dhawan Space Center (SDSC) in Sriharikota on January 12.
Isro's Cartosat constellation consists of a series of satellites in sun-synchronous orbit making panchromatic and multispectral images of the Earth's surface.
Pakistan has protested the launch of Cartosat-2.
Microsatellite (India): This is a 100 kg class satellite meant for technology demonstration and the fore runner for future satellites of this series.
The 31 satellites were placed in two different orbits in one mission, in one of the keenly watched missions that comes after a failed launch in August previous year.
The performance of the deployed Cartosat-2 was satisfactory as monitored by the mission control facility, Kumar added. Cartosat will be used for capturing high-quality images for rural-urban applications and also for utility managements like road network monitoring. Sivan is set to take charge as the new Isro chairman by next week.
After that 30 other smaller satellites are placed one by one.
Among the 28 worldwide co-passenger satellites that were deployed into multiple orbits, 19 belong to the U.S., five to South Korea and one each to Canada, France, the United Kingdom and Finland. The first stage of GSLV-MII is already assembled and the preparations are on for its launch.
