India’s ISRO will launch five British satellites on July 10, 2015

The Indian Space Research Organisation (ISRO) has undertaken the heaviest ever commercial mission, accompanied by commercial arm Antrix.

Polar Satellite Launch Vehicle (PSLV) handles putting five foreign satellites. The launch will be made from the spaceport of Sriharikota in Andhra Pradesh.

The average mass of the five satellites is roughly estimated to be around 1,440 kg, which could be the heaviest commercial mission that ISRO and Antrix have undertaken yet.

PSLV-C28, on its 13th flight, will launch DMC3, three identical satellites for optical Earth observation satellites have been believed by SSTL, Surrey Satellite Technology Limited from United Kingdom (UK).

Three of the DMC3 satellites weigh 447 kg. They will be launched into the SSO (Sun-Synchronous Orbit), at a distance of 647 km. The launch will be performed by the PSLV, designed at the higher end, as stated by ISRO.

In the ‘XL’ configuration, PSLV-C28 will be the ninth flight of PSLV.

The rocket is also said to carry, also, two auxiliary satellites like UK- CBNT-1.

This is a microsatellite built by SSL, as a technology demonstrator earth observer. The other satellite includes De-OrbitSail, which was built by Surrey Space Centre. This is another technology demonstrator that is available in the size of a nanosatellite.

ISRO has stated that accommodating three 3-metre high DMC3 in the PSLV was challenging.

A circular launcher adapter called L-adaptor as well as a Multiple Satellite Adapter-Version 2, which is a triangular deck, had been designed newly as well as realized by ISRO.
