IRS-1D, both of which have far outlived their designed mission lives, but also vastly enhance the data quality. The 1360 kg IRS-P6 will be launched into an 817 km high polar Sun Synchronous Orbit by the eighth flight of India's
Polar Satellite Launch Vehicle (PSLV-C5).
IRS-P6
carries three cameras similar to those of IRS-1C and IRS-1D
but with vastly improved spatial resolutions _ a high resolution Linear
Imaging Self Scanner (LISS-4) operating in three spectral bands
in the Visible and
Near Infrared Region (VNIR) with 5.8 metre spatial resolution and
steerable
up to+_ 26 deg across track to obtain stereoscopic imagery and achieve
five day revisit capability; a medium resolution LISS-3 operating
in three spectral bands in VNIR and one in Short Wave Infrared
(SWIR) band with 23.5 metre spatial resolution; and an Advanced
Wide Field Sensor (AWiFS) operating in three spectral bands in
VNIR and one band in SWIR with 56 metre spatial resolution.
IRS-P6 also carries a Solid State Recorder with a capacity of 120 Giga Bits to store the images taken by its cameras which can be read out later to the ground stations.
