Instruments
Resourcesat-1 carries three cameras similar to those of IRS-1C and IRS-1D but with vastly improved spatial resolutions - a high resolution Linear Imaging Self-Scanning Sensor-4 (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° across track to obtain stereoscopic imagery and achieve five-day revisit capability; a medium resolution Linear Imaging Self-Scanning Sensor-3 (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.
Resourcesat-1 also carries a solid state recorder with a capacity of 120 Gigabits to store the images taken by its cameras which can be read out later to the ground stations.
