The Indian Space Research Organization’s (ISRO) Polar Satellite Launch Vehicle (PSLV) launched five satellites, for a United Kingdom-based company. These satellites are reported to be weighing 1,440 kg. PSLV C-28 launched 3 identical mini satellites for the Disaster Monitoring Constellation (DMC), and 2 technology demonstrators, i.e. CBNT-1 and De-OrbitSail.
ISRO chairman termed it as an extremely successful mission, as it was a challenge for the research organization to manage 3-metre high satellites into the payload structure of PSLV. Hence, the national space agency specially designed a triangular deck and a circular launch adapter. The DMC satellites will be fine-tuned into the Sun Synchronous Orbit of 647-km.
This launch for five satellites marked the 30th successful mission of PSLV. It is also reported that the national space agency used the XL version ninth time.
The mini DMC satellites have been designed in a way that it provides simultaneous high temporal resolution and spatial resolution for earth observation.
Besides monitoring disasters, all the three satellites are aimed at subjugating any target on the Earth’s surface and would help in surveying environment, resources and urban infrastructure.
Earlier, the PSLV had launched 40 satellites for 19 countries.
