The ‘sharpest eye in the sky’, India’s Cartosat-3, and 13 other nano satellites belonging to two companies in the U.S. lifted off successfully from the Satish Dhawan Space Centre SHAR, Sriharikota, at 9.28 a.m, offering only a very brief glimpse of the PSLV C-47 before vanishing into the low-hanging clouds.


The Cartosat-3 is a high resolution imaging satellite that will be used for addressing uses for largescale urban planning, infrastructure development, coastal land use, land cover among others. The satellite is also likely to have a military use since it provides highest-ever spatial resolution of about a foot.

The Cartosat-3 was separated about 18 minutes after lift-off and the customer satellites were injected into their planned orbits one by one and the mission was completed 27 minutes after launch.

9th satellite

The Cartosat-3 is the 9th satellite of the Cartosat series and ISRO’s fifth launch this year. One of its cameras offer a ground resolution of 25 cm, while the best ground resolution till now was 31 cm offered by WorldView-3, a satellite owned by U.S. company Maxar.

The commercial satellites (belonging to US companies) carried on board in the mission were launched under a commercial arrangement with NewSpace India Ltd. (NSIL), the commercial arm of the ISRO.
