The Indian Space Research Organisation is to build a remote sensing satellite, Cartosat-3, capable of taking images of the earth with a resolution of 0.25 metres.
Currently, GeoEye-1 produces the highest resolution earth images taken by a commercial satellite. The American spacecraft, launched in September 2008, is capable of taking panchromatic images with 0.41 metre resolution. WorldView-2, another satellite operated by the same company, DigitalGlobe, offers a best resolution of 0.46 metres. However, in accordance with U.S. regulations, commercially released images from these satellites are degraded to 0.5 metre resolution.
DigitalGlobe plans to launch WorldView-3 next year, which will supply images with a resolution of 0.31 metres. Cartosat-3’s camera would better that performance. In the words of one expert, this satellite's images could allow a scooter to be distinguished from a car.
In the ‘Notes on Demands for Grants, 2013-2014’ from the Department of Space, which forms part of the budget documents presented to Parliament recently, Cartosat-3 figures as a separate item with an allocation of Rs. 10 crores. “Cartosat-3 is an advanced remote sensing satellite with enhanced resolution of 0.25 metre for cartographic applications and high-resolution mapping,” the document said.
IN 1988, ISRO launched India’s first operational remote-sensing satellite, IRS-1A. The best resolution its cameras could provide was about 36 metres. Seven years later, IRS-1C went into space, with a panchromatic camera that had a resolution of 5.8 metres. It supplied the highest resolution images available from any civilian satellite in the world till Ikonos, an American satellite launched in 1999, began taking images with better than one-metre resolution. India launched the Technology Experiment Satellite in 2001, followed some years later by the Cartosat-2 series of satellites that could take images with 0.8 metre resolution.

Thats good news

From ISRO facebook page.
Three big missions this year...
PSLV C22 with IRNSS 1 - the first navigation satellite in the Indian Regional Navigation Satellite System (IRNSS) scheduled to lift in May, 2013.
GSLV D5 with the India make cryogenic stage, lift off from the second launchpad in Sriharikota the same month.
And another PSLV will lift off with the Mars mission in October, 2013.

On March 17, 2013, India will attain the milestone of 25 years of successful operations of Earth Observation services by the Indian Remote Sensing Satellites, ever since the launch of IRS 1A on March 17, 1988.

Model of ISRO’s launch vehicle handed over
Speaker G Karthikeyan on Wednesday handed over an ‘executive’ model of the GSLV Mk III launch vehicle of the Indian Space Research Organisation (ISRO) to GSLV Mk III project director S Somanathan of the Vikram Sarabhai Centre (VSSC) at a function here.
The model has been constructed by Intimate Machines Pvt Ltd, a Micro, Small and Medium Enterprises (MSME) unit which manufactures aerospace components.
According to a statement issued by Intimate Machines, the launch vehicle model was so precisely made that it can be used for conducting wind tunnel tests for determining aerodynamic characterisation. The company had won its first order for building aerospace components for PSLV and GSLV launch vehicles in 2006.

ISRO said they launched risat-2 for disaster and crop management and it will help indian gov to astimate argriculture output. But in this poster they given pics of karachi airport i think they are more interested in Pakistani crops.
risat-2 is for only indian gov use not for commercial use

Some pictures of GSAT-10 launched in September 2012
The shipping container that protected GSAT-10 during its travels from India to French Guiana is removed inside the Spaceport's S5 payload preparation facility.
GSAT-10 “spreads its wings” in preparation for Arianespace’s next Ariane 5 launch on 21st Sept.

Can someone explain me?
What's the difference between GSLV markII and GSLV markIII? both will be using Indian made cryogenic engine so what are differences?
What is GSLV D5 as it mentioned on ISRO facebook page will lift of on May.
GSLV MarkII
GSLV MarkIII
GSLV D5
how these 3 differ?

GSLV mk2 uses CE-7.5 engine that produces around 75kn of thrust while,GSLV mk3 uses CE-20 engine .It works on Gas generator cycle,and produces thrust of 200KN.
Its GSLV mk2.
GSLV is technological successor of GSLV mk2 however is not derived from its predecessors.GSLV mk3 is different from GSLV starting form booster stage to cryogenic stage.
Booster 1st stage 2nd stage 3rd stage
GSLV mk2 4*vikas 2 S-139 Vikas 4 CE-7.5
GSLV mk3 2*S-200 L-110 CE-20 None
Payload of GSLV mk3 is 4-5 tonnes to GTO,compared to 2.2 GTO of GSLV mk2

Actually, ISRO names each of it's rockets acc. to technological leap it has taken.
GSLV Mk-2 is the general name given to GSLV rocket whose payload capacity 5 tonne to LEO (2-3 tonne to GTO) & uses an Indian cryogenic engine, this is the difference from GSLV mk-1 where the payload capacity was same but the cry. engine was that of Russia.
GSLV Mk-3 on the other hand is completely different rocket than GSLV, just like the difference b/w PSLV & GSLV, but ISRO has kept the name as it is. While it uses an Indian cry engine, but it's payload capacity will be much more than mk-1 & mk-2 as it will be able to carry 5 tonne sats to GTO & 10 tonne sats to LEO. It has completely different design than GSLV with reduced height & increased weight.
GSLV D-5 is nothing but a specific flight name given to a Mk-2 rocket by ISRO that will launch GSAT 14 into the orbit.
