What new type of satellite is proposed to be inducted for bolstering surveillance on India’s border?

The new proposed satellite in CARTOSAT. It is proposed to because the existing IRS Satellites were not able to defect the army in Kargil recently. Due to failure, India had to rely on the figures of soldiers given by foreign satellites.

The meters of size while the new CARTOSAT will be able to detect up to 2.5 meters size objects with 3-D picture.

However, CARTOSAT is basically not a satellite for military surveillance but it is for mapping technology yet, it can be used by military for those purposes also to some extent.
