ISRO is all set to launch its heaviest commercial payload weighing in at 1,440 kg on board the PSLV-C28 from Sriharikota spaceport today at 9:58 pm.
The 44.4 meter tall PSLV-XL space vehicle will carry five British satellites, putting three of the larger ones into a 647 km Sun-Synchronous Orbit (SSO).
PSLV, on its 30th mission, is carrying three identical DMC3 optical earth observation satellites weighing 447kg each and built by UK-based Surrey Satellite Technology Limited (SSTL).
The three DCM3 satellites are designed for simultaneous high spatial resolution and high temporal resolution optical Earth Observation.
They will be used for surveying the resources on earth and its environment, managing urban infrastructure and monitoring disasters.
The mission will also put two technology demonstrator auxiliary satellites into space – the CBNT-1 and De-OrbitSail.
