Indian remote sensing
The Indian Remote Sensing Satellites ( IRS ) are a series of Indian Earth observation satellites in Low Earth Orbit (LEO). Built by the Indian Space Research Organization , they are typically launched with the Indian PSLV launcher from the Satish Dhawan Space Center on Sriharikota. They are an essential part of the Indian space program and are used for weather forecasting, but especially for scientific and agriculturally oriented earth observation. Since 1999 the satellites have also had proper names that reflect their intended use and start with so-called secondary payloads or piggyback payloads, for example 1999 DLR-TUBSAT and KITSAT-3.
India participates with the IRS in the International Charter for Space and Natural Disasters .
