Taking India’s massively successful program to new highs, ISRO today successfully launched the fourth satellite under the IRNSS Navigational system, called the IRNSS 1D. And as has already been attributed to previous iSRO launches, this launch too was categorised by ISRO’s clinical precision.

IRNSS-1D, which is the fourth satellite among the seven of the IRNSS constellation of satellites. IRNSS is slated to be launched to provide navigational services to the subcontinent region, along with portions of China and South Asia. The satellite will be placed in geosynchronous orbit.


ISRO had successfully launched the third series of IRNSS satellites, the IRNSS-1C in October last year. It was launched aboard India’s massively successful PSLV rocket. The previous launch marked the twenty seventh consecutively successful mission of PSLV. The ‘XL’ configuration of PSLV was used for this mission. Previously, the same configuration of the vehicle was successfully used six times.

IRNSS, being developed indigenously by ISRO, when complete, will put India into a selet club of nations, with their own satellite navigation satellites in space. If you do not know what a navigation satellite system is, it is the technical term of your very popular GPS and GLONASS. IRNSS is India’s own, 7-satellite strong regional navigation satellite system, deployed specially to keep a close watch on the Asian region, and counter China’s growing influence over the region.
