The primary goal of the HysIS satellite is to study the Earth's surface in various electromagnetic regions. The HysIS satellite, also known as the Hyperspectral Imaging Satellite, is an Indian satellite that was launched in November 2018. It is designed to capture images of the Earth's surface using hyperspectral imaging technology.

Hyperspectral imaging is a technique that allows the capture of images in many different wavelengths of the electromagnetic spectrum. Unlike traditional satellite imaging, which captures images in a few broad bands of the spectrum, hyperspectral imaging captures images in hundreds of narrow and contiguous bands. This enables more detailed analysis and interpretation of the data collected.

The HysIS satellite carries a payload of a hyperspectral sensor that captures images in the visible, near-infrared, and shortwave infrared regions of the spectrum. This sensor is capable of capturing images with a resolution of 30 meters and a swath width of 30 kilometers.

By studying the Earth's surface in various electromagnetic regions, the HysIS satellite aims to gather data on various aspects such as land use, vegetation, mineralogy, coastal zones, and snow or ice cover. This data can be used for a wide range of applications including agriculture, forestry, urban planning, disaster management, and environmental monitoring.

The hyperspectral imaging data collected by the HysIS satellite can provide valuable insights into the composition and health of the Earth's surface. For example, it can help identify different types of crops, detect changes in vegetation cover, monitor the health of forests, identify mineral deposits, and track changes in coastal regions.

In addition to its primary goal of studying the Earth's surface, the HysIS satellite also serves as a technology demonstrator for future Indian remote sensing satellites. It provides valuable data and experience that can be used for the development of more advanced satellite systems in the future.

Overall, the primary goal of the HysIS satellite is to study the Earth's surface in various electromagnetic regions using hyperspectral imaging technology. This data can be used for a wide range of applications and contribute to our understanding and management of the Earth's resources and environment.
