Here is a list of ISRO’s biggest launches over the last 2 years that showcase India’s space prowess

​The first experimental flight of heavy-lift next generation launch vehicle, GSLV-Mk III, was successfully conducted on December 18, 2014 from Sriharikota. This flight has validated the complex atmospheric regime of flight and demonstrated the Integrity of design of GSLV Mk III.

ASTROSAT satellite, India’s first dedicated astronomy satellite was successfully launched by PSLV-C30 on September 28, 2015. ASTROSAT enables simultaneous Ultraviolet to X-Ray observations to study Stars and Galaxies. It will also provide opportunity to task observations for the scientific community.

GSAT-15, India’s latest Communication Satellite is a high power satellite being inducted into the INSAT/GSAT system. It carries a total of 24 communication transponders in Ku-band as well as a GPS Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands. GSAT-15 was launched by Ariane-5 VA-227 launch vehicle from Kourou, French Guiana on early morning of November 11, 2015.

This was the seventh consecutive successful launch of the navigation satellite-IRNSS-1G in April 2016. With this, India became self-sufficient with indigenous navigation system. This was quite important and historic for India as the US had denied GPS assistance to India during the Kargil war with Pakistan.

ISRO showcased its commercial launch capability after it successfully launched five satellites for the UK in July 2015. In less than 20 minutes after the launch, the rocket placed in the designated orbits three identical DMC3 optical earth observation satellites, an auxiliary earth observation micro satellite (CBNT-1) and one technology demonstrator nanosatellite (De-OrbitSail), built by SSTL.
