Indian Remote Sensing Satellites Applications

Indian Remote Sensing (IRS) satellites are primarily used for Earth observation and resource management applications. Statements 1, 2, and 3 are correct: IRS satellites are extensively used for crop productivity assessment (agricultural monitoring), groundwater resource location (hydrogeological surveys), and mineral exploration (geological mapping). Statement 4 (telecommunications) is incorrect as IRS satellites are not designed for telecommunications—dedicated communication satellites like INSAT serve that purpose. Statement 5 (traffic studies) is partially possible but not a primary application of IRS satellites. Therefore, only 1, 2, and 3 represent the main uses of IRS satellites. > IRS Satellites Remember: IRS = Assessment, Locating, Minerals (Earth observation focus, not communications) Answer: (a).
