India Launched All-Weather Accessory RISAT-1

India's aboriginal aboriginal all-weather alarm imaging accessory (RISAT-1), whose images will facilitate agronomics and adversity management, was today launched auspiciously on lath the PSLV-C19 from here.

The 1,858 kg spacecraft, the country's aboriginal bake alien analysis satellite, was injected into apogee by the Polar Accessory Barrage Agent about 19 account afterwards a absolute lift off at 5.47 am at the end of the 71-hour admission from the Satish Dhawan Amplitude Centre here, about 90 km from Chennai.

Indian Amplitude Research Organisation's crammer barrage agent PSLV yet afresh accepted its believability
commutual its 20th acknowledged flight in a row ablution RISAT-1, the heaviest accessory anytime aeriform by it.

RISAT-1, acme of about ten years of accomplishment by ISRO, has the adequacy to booty images of the apple during day and night as able-bodied as in blurred conditions. Till now, India depended on images from a Canadian accessory as absolute calm alien analysis aircraft cannot booty pictures of apple during billow cover.

Lifting off in the accomplishments of blood-soaked East from the aboriginal barrage pad, the 44-metre alpine rocket soared majestically into the sky in a mission declared as 'a admirable success' by ISRO Chairman K Radhakrishnan.

It was a arbiter barrage with anniversary of the four stages of the rocket assuming as programmed and the scientists at the mission ascendancy centre bankrupt into acclaim back the accessory was injected into orbit.

"I am acutely blessed to advertise that the PSLV C-19 mission is a admirable success. This is the 20th alternating acknowledged flight of our PSLV. It injected absolutely India's aboriginal alarm imaging accessory into the adapted orbit," a bright Radhakrishnan said.

India had in April 2009 launched a Alarm Imaging Accessory (RISAT-2) with all acclimate adequacy but it was bought from Israel for USD 110 actor abundantly for

surveillance purposes.

RISAT-1 was launched application the advanced new Mission Ascendancy Centre for the aboriginal time afterwards its commencement by President Pratibha Patil in January, Mission Director P Kunhikrishnan said.

The barrage of RISAT-1 was originally slated for March but the ISRO row, the fall-out of the castigating activity adjoin four above amplitude scientists for their role in the Antrix-Devas deal, casting a adumbration allegedly dabbling the preparations.

ISRO acclimated PSLV-XL, high-end version, alone third such instance, for today's launch. The XL adaptation was beforehand acclimated for Chandrayaan-1 and GSAT-12 missions.

The accustomed amount of RISAT-1, including its development, is Rs 378 crore, while Rs 120 crore has been spent to body the rocket (PSLV-C19), authoritative it a Rs 498-crore mission.

The spacecraft, which would be anchored at its final apogee of 536 km altitude, has a mission activity of bristles years and would accomplish 14 orbits per day.

Besides use in the agronomics sector, RISAT-1 could additionally be acclimated to accumulate ceaseless acuity on the country's borders, but ISRO admiral had said this accessory would not be acclimated for defence applications. RISAT-2, primarily a spy spacecraft, is already accomplishing that job.

RISAT-1's adequacy to booty images in all acclimate distance including fog and brume would be a benefaction for regions perennially beneath billow cover.

The accessory carries a C-band Synthetic Aperture Alarm (SAR) payload, operating in a multi-polarisation and multi-resolution approach to accommodate images with coarse, accomplished and aeriform spatial resolutions respectively.

The different characteristics of SAR accredit applications in agriculture, decidedly paddy ecology in kharif division and administration of accustomed disasters like flood and cyclone.

The accessory would be decidedly advantageous in Kharif division back cloud-covered atmosphere is frequent. Images taken from the aircraft of agronomical crops would accredit planners with attention to assembly admiration and forecast.

During floods, aeriform pictures would accord a bright abstraction on the afflicted arena and baptize level.
