ISRO is probably the best translation to a modern, fast developing India. And ISRO’s continued successful and clinical precision launches are a testimony to the talent Indian Space scientists possess. Duplicating its ongoing success stint so far, ISRO today successfully put to orbit, 5 UK satellites in its heaviest commercial space launch till date.
The Polar Satellite Launch Vehicle (PSLV), in its thirtieth flight (PSLV-C28), launched three identical DMC3 optical earth observation satellites built by Surrey Satellite Technology Limited (SSTL), United Kingdom (UK).
The three DMC3 satellites, each weighing 447 kg, launched into a 647 km Sun-Synchronous Orbit (SSO) using the high-end version of PSLV (PSLV-XL) from Satish Dhawan Space Centre, Sriharikota (SDSC-SHAR), the spaceport of India. PSLV-C28 will be the ninth flight of PSLV in ‘XL’ configuration.
The PSLV-C28, in addition to the three DMC3 satellites, also carried two auxiliary satellites from UK, viz., CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Centre.
With the overall lift-off mass of the five satellites amounting to about 1440 kg, this mission becomes the heaviest commercial mission undertaken by Antrix/ISRO till date.
These international customer satellites have been launched as part of the arrangement entered into between DMC International Imaging (DMCii), a wholly owned subsidiary of SSTL, UK; and Antrix Corporation Limited (Antrix), the commercial arm of Indian Space Research Organisation (ISRO), a Government of India Company under Department of Space.
