The Indian Space Research Organisation (ISRO) has outlined a robust plan to launch a series of state-of-the-art satellites. These advanced satellites are designed to augment operational applications and accommodate the requirements of emerging applications. We will be looking into the details of these unique space tools that have been approved for launch till 2019-20.
Third Generation Cartosat Series Satellite
This is a system designed explicitly for very high resolution mapping. The intention behind the launch of the Cartosat satellites is to provide superior remote sensing services. The images transmitted by this series of satellites will play a significant role in coastal land use and regulation, road network monitoring, water distribution, and the creation of land use maps.
Stereo Imaging Satellite
Also known as stereoscopy or 3D imaging, stereo satellite imaging is a technique traditionally used to create depth illusion in images. In the context of remote sensing applications, it involves taking photographs of the earth, then generating 3D topographic maps and computer models using these stereo images.
Geostationary Imaging Satellite (GISAT)
This is a type of earth-observing satellite that operates from geostationary orbit. This strategic positioning facilitates continuous observation of the Indian sub-continent, along with prompt monitoring of natural hazards and disasters. Geosynchronous orbits are high Earth orbits that enable satellites to align with Earth’s rotation, making them ideal for weather monitoring, communications, and surveillance.
Ocean Imaging Satellite
This third generation satellite focuses primarily on ocean colour, sea surface temperature mapping, and ocean surface wind vector mapping. The resulting data can offer valuable insights into climate change, marine life, and ocean currents.
ResourceSat Series Satellite
Part of the third generation ResourceSat series, these satellites boast improved spatial resolution and swath. Their primary function is to provide data for integrated land and water resource management. The satellites operate in a sun-synchronous orbit at an altitude of 817 km, completing approximately 14 orbits daily.
High-resolution Imaging Satellites
This constellation of satellites allows for frequent re-visits, providing researchers with valuable, up-to-date information about various aspects of the Earth’s surface.
Nanosatellite for Aerosol Monitoring
A “nanosatellite” is a term usually associated with an artificial satellite that weighs between 1 and 10 kg. These compact devices often work in groups, sometimes referred to as “swarms.”
Satellite for Monitoring Chlorophyll Fluorescence and Radiation Environment
This satellite is specialized in monitoring chlorophyll fluorescence, a non-invasive measurement of photosystem II (PSII) activity, often used in plant physiology. The detection of PSII activity changes gives an indication of how plants respond to environmental changes. This data can be crucial in predicting and addressing issues related to climate change and agricultural productivity.
