Risat1

The Resourcesat-1 satellite, also known as IRS-P6, was an Indian Remote Sensing satellite launched by the Indian Space Research Organisation (ISRO). It was launched on October 17, 2003, from the Satish Dhawan Space Centre in Sriharikota, India. Resourcesat-1 was part of ISRO's ongoing program to develop and deploy advanced remote sensing capabilities for Earth observation.

The primary mission of Resourcesat-1 was to provide data for various applications, including agriculture, forestry, water resources management, and land use planning. It carried a suite of sophisticated payloads designed to capture high-resolution imagery of the Earth's surface. These payloads included a Linear Imaging Self Scanner (LISS-III) camera, a Multispectral Optoelectronic Scanner (MOS-2), and a Advanced Wide Field Sensor (AWiFS). LISS-III provided multispectral data in visible and near-infrared bands with a spatial resolution of 23.5 meters. MOS-2 offered higher spectral resolution, while AWiFS provided wider coverage with a resolution of 56 meters.

Resourcesat-1 orbited the Earth in a sun-synchronous polar orbit, enabling it to revisit the same locations repeatedly and capture data under consistent lighting conditions. The satellite was designed for a mission life of five years, but it continued to operate and provide valuable data for a significantly longer period. The data from Resourcesat-1 played a crucial role in various national and international projects, contributing to scientific research and socio-economic development. It was succeeded by the Resourcesat-2 satellite, which carried on the legacy of advanced Earth observation.
