The latest launch comes almost five months after the launch of ISRO's IRNSS-1H satellite, its eighth regional navigation satellite, was unsuccessful.
After a lull following a rare failure in August 2017, the Indian Space Research Organization (Isro) has a packed schedule this year, with the first launch scheduled for Friday, also taking the 100th indigenous satellite into orbit.
The total weight of all the 31 satellites carried on-board the PSLV-C40 is about 1323 kg.
In yet another display of its growing prowess in space exploration, India on Friday successfully launched 31 satellites in a Polar Satellite Launch Vehicle (PSLV) from its spaceport in Sriharikota, Andhra Pradesh.
"When the last satellite is ejected out it will become the hundredth satellite.the first century we have done", ISRO Satellite Centre (ISAC) director M Annadurai had told PTI.
This will be ISRO's first launch in 2018 and also the first after the unsuccessful mission of IRNSS-1H in August a year ago.
Chances of U.S. leaving NAFTA must be taken seriously: Canada
Trade officials from Mexico, Canada and the United States have put a March deadline on completing negotiations on NAFTA. Discussions to redraft the 23-year old trade pact between Mexico, Canada and the USA have been thorny.
The Cartosat-2 remote-sensing satellite is the main payload aboard the PSLV C-40.
The launch is estimated to take 7 minutes and 15 seconds, and the telecast will be both in Hindi and English.
Isro's trusted workhorse PSLV will carry the weather observation "Cartosat-2" series satellite and 30 co-passengers at lift-off.
About 17 minutes 18 seconds after the lift off, the Cartosat-2 series will be separated and injected into its 505 km sun synchronous orbit. It will boost data services for urban and rural applications, coastal land use and regulation, monitoring of road networks, water distribution, and land-use mapping, said an HT report.
The mission will be 42nd flight that will lift off from the Satish Dhawan Space Centre. The surveillance satellite from the "Cartosat 2" series will keep watch on India's hostile neighbours.
