Microsat-R, an imaging satellite, is meant for military purposes, but the ISRO did not give any details about it.
Heralding a new era, India on Friday night launched its heaviest commercial space mission ever with its polar rocket successfully putting five British satellites into the intended orbit after a flawless takeoff.
INSAT-3D, developed by the Indian Space Research Organisation and its Space Applications Centre, is designed to provide meteorological observation and monitoring of land/ocean surfaces.
India scripted history by successfully launching EMISAT, a military satellite, and 28 foreign nano satellites on-board its polar rocket from Sriharikota on Monday, in a complex mission which marked many a first for Indian Space Research Organisation.
The mission life of the 2,250kg GSAT-7A, built by ISRO, is eight years. It will provide communication capability to users in Ku-band over the Indian region.
Indian Space Research Organisation's plan to soft land Chandrayaan-2's Vikram module on the Lunar surface did not go as per script in the early hours of Saturday, with the lander losing communication with ground stations during its final descent.
Just over 22 minutes into the flight, the rocket put Astrosat into orbit at an altitude of 650 km above the earth
The satellite would provide a thrust to mobile communication through multi-beam coverage facility, the ISRO said.
It also carries equipment for meteorological data relay and satellite based search and rescue services being provided by earlier INSAT satellites.
In a textbook mission, ISRO's PSLV-C32 lifted off from Sriharikota and later injected the IRNSS-IF in sub-Geosynchronous Transfer Orbit.
GSAT-18, which aims at providing telecommunications services for the country by strengthening ISRO's current fleet of 14 operational telecom satellites, was launched into a Geosynchronous Transfer Orbit about 32 minutes after the lift-off.
Other than the Cartosat-2 series satellite, the PSLV is carrying 29 nano satellites from 14 countries - Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, the United Kingdom and the United States of America besides a nano satellite from India.
PSLV C-29 blasted off from the Satish Dhawan Space Centre, about 110 km from Chennai, at 6 pm and released the six satellites one by one into a 550 km circular orbit.
Missile's range to cover China, West Asia, South East Asia and large parts of Africa
