Cartosat-2B is an Indian mapping satellite launched on PSLV-C15 in July 2010. Like Cartosat-2 and 2A, it carries a camera that sees details smaller than one metre.
ISRO calls it the seventeenth satellite of the Indian Remote Sensing series. Its panchromatic camera covers a strip 9.6 km wide at a resolution better than one metre.
The satellite can tilt up to 26 degrees forward, backward or sideways. Tilting lets it photograph the same place from two angles to make 3D (stereo) images, and to come back to a place every four to five days.
Cartosat-2B weighed 694 kg at launch and its solar panels give 930 W. Star sensors and gyros measure which way it points; reaction wheels, magnetic torquers and hydrazine thrusters turn it.
PSLV-C15 launched it from Sriharikota on 12 July 2010. This was PSLV's seventeenth flight and its sixth in the "core alone" form, without strap-on boosters.
The satellite went into a polar sun-synchronous orbit about 630 km high. The student satellite STUDSAT and three foreign satellites (AlSat-2A, AISSat-1 and TIsat-1) flew on the same rocket.
The public satellite catalogue still carries Cartosat-2B with an operational flag. That flag is not confirmation from ISRO that the satellite is still working, so treat its current status as unconfirmed.
