The Indian earth observation satellite IRS-P3 (Indian Remote Sensing) was launched into low earth orbit in March 1996. Besides the WiFS (Wide Field Sensor) instrument it carried MOS (Modular Optoelectronic Scanner), an imaging spectrometer for the visible and near-infrared range developed and provided by DLR. It is being used to investigate and monitor the ocean-atmosphere system, particularly in coastal regions.
