Indian officials say images collected by the satellites will be used to track military activities in neighbouring countries Pakistan, China, Bangladesh, Sri Lanka and Nepal.
India launched its 100th satellite on Friday as Prime Minister Narendra Modi seeks to project the country as a global low-cost provider of services in space.
A total of 31 small satellites were launched into space. More than half of the micro and nano satellites were for the United States, and the remainder for India, Canada, Finland, France, South Korea and the United Kingdom.
"The launch of the 100th satellite by @isro signifies both its glorious achievements and also the bright future of India's space programme," Modi wrote on Twitter.

India's space programme has a budget of around $4 billion and Modi's government hopes the latest launches will improve its prospects of winning a larger share of the more than $300 billion global space industry.
Modi's government has been promoting a domestic space programme as a demonstration of low-cost technology and last February launched 104 satellites in a single mission, most of them for foreign customers.
Indian Space Research Organisation (ISRO) used its workhorse Polar Satellite Launch Vehicle (PSLV-C40), part of an advanced remote sensing satellite Cartosat-2 series or "eye in the sky," for the Friday launch from Sriharikota in southern Andhra Pradesh state at 0358 GMT.
The rocket weighs about 1,323 kg, said a senior official at state-run ISRO, who did not wish to be named.
India will use its latest satellites for better border surveillance and obtaining high-resolution images of the earth.
"PSLV-C40 is a highly sophisticated surveillance tool to keep an eye on Indian borders and will help the government track progress of infrastructure projects," said Pallava Bagla, a science writer and co-author of Reaching for the Stars: India's Journey to Mars.
Two scientists at ISRO said images collected by the satellites would be used by the Indian security agencies to track military activities in neighbouring Pakistan, China, Bangladesh, Sri Lanka and Nepal.
