Sensor Specifications: IRS-P6



Indian Remote Sensing (IRS) P6 (RESOURCESAT-1) was launched in October 2003. This satellite carries three different imaging sensors: Linear Imaging Self Scanner (LISS) 3 and 4 and an advanced Wide Field Scanner (AWiFS). The LISS 3 instrument is multispectral in the visible to mid-infrared region with a spatial resolution of 24m and swath width of 140km. The LISS 4 instrument has two modes that both operate at a spatial resolution of 6m. The multispectral (visible to near-infrared) instrument has a swath width of 24km and 70km for the panchromatic (monochrome) mode. The AWiFS has a spatial resolution of 60m and a 740km swath width. Both LISSs have 7-bit radiometric resolution, while the AWiFS has 10-bit.

This satellite has a polar, circular, sun-synchronous 800-km orbit with a 24-day repeat cycle for the LISS 3 sensor and a 5-day repeat cycle for the steerable LISS 4.
