Cartosat - 2B

Cartosat-2B                                                                                             Launch Date : 12.07.2010

CARTOSAT - 2B is the seventeenth satellite in the Indian Remote Sensing Satellite series (IRS). CARTOSAT-2B carries a Panchromatic camera (PAN) similar to those of its predecessors - CARTOSAT-2 and 2A. It is capable of imaging a swath (geographical strip) of 9.6 km with a resolution of better than 1 metre. The scene specific spot imagery sent by CARTOSAT-2B's PAN will be useful for cartographic and a host of other applications. The highly agile CARTOSAT-2B is steerable up to ± 26^o along as well as across track to obtain stereoscopic imagery and achieve a four to five day revisit capability.

Oceansat - 2

 Oceansat - 2                                                                      Launch Date : 23.09.2009

Oceansat-2 satellite mainframe systems derive their heritage from previous IRS missions and launched by PSLV-C14 from Satish Dhawan Space Centre, Sriharikota on Sept. 23, 2009. It carries three payloads:

• Ocean Colour Monitor (OCM)
• Ku-band Pencil Beam scatterometer (SCAT) developed by ISRO
• Radio Occultation Sounder for Atmosphere (ROSA) developed by the Italian Space Agency.

Oceansat-2 is envisaged to provide continuity of operational services of Oceansat-1(IRS-P4) with enhanced application potential.
