ISRO Soars High with INSAT-3DS: Boosting Weather Forecasting and Disaster Management


On February 17, 2024, the Indian Space Research Organisation (ISRO) successfully launched the INSAT-3DS mission, marking a significant milestone in India’s space journey. This state-of-the-art weather satellite promises to revolutionize the country’s weather forecasting capabilities, disaster management preparedness, and environmental monitoring.

Unveiling the Purpose:

The primary objective of INSAT-3DS is to enhance India’s meteorological observations and analysis. With advanced imaging instruments, it will provide crucial data on various atmospheric parameters like cloud cover, rainfall, temperature, and humidity. This improved data will empower weather agencies to deliver more accurate and timely forecasts, crucial for mitigating the impact of extreme weather events.

Cost-Effective Innovation:

Developed completely indigenously, the INSAT-3DS mission embodies ISRO’s commitment to cost-effective space exploration. The total project cost is estimated at approximately ₹14,000 crores, showcasing India’s ability to achieve cutting-edge technology within reasonable budgetary constraints.

Reaching the Right Orbit:

INSAT-3DS is now placed in a geostationary orbit at an altitude of approximately 36,000 kilometers above the equator. This vantage point allows it to continuously monitor a specific region, providing vital data over a large geographical area.

Lifting Off with Power:

The powerful Geosynchronous Satellite Launch Vehicle Mk-II (GSLV-MkII), designated GSLV-F14 also called ‘NAUGHTY BOY’, carried the INSAT-3DS satellite into orbit. This launch vehicle represents the pinnacle of ISRO’s rocket technology, capable of propelling heavy payloads into designated orbits.

Eyes on the Sky:

INSAT-3DS boasts a sophisticated payload consisting of four imaging instruments:

  • Improved Imaging Infra-Red Sounder (ImagIR): Provides detailed information on atmospheric temperature, moisture, and cloud top heights.
  • Advanced Very High-Resolution Radiometer (AVHRR): Delivers visible, infrared, and near-infrared imagery for monitoring cloud cover, land surface features, and sea surface temperatures.
  • Data Relay Transponder (DRT): Enables real-time data transmission from smaller meteorological stations and platforms.
  • Search and Rescue Transponder (SART): Assists in locating ships and aircraft in distress situations.

Beyond Weather:

While weather forecasting remains the core objective, INSAT-3DS offers additional benefits:

  • Ocean Monitoring: Enables continuous monitoring of sea surface temperature and wind speeds, aiding in maritime weather forecasting and understanding oceanographic phenomena.
  • Climate Change Studies: Provides valuable data for analyzing climate patterns and trends, crucial for climate change mitigation strategies.
  • Disaster Management: Improved weather forecasts and insights into extreme weather events empower authorities to take timely preventive measures and minimize disaster impact.

The successful launch of INSAT-3DS marks a significant leap forward for India’s space program. This advanced satellite promises to enhance weather forecasting accuracy, strengthen disaster preparedness, and provide valuable data for environmental monitoring, solidifying India’s position as a leader in space technology and contributing to the betterment of lives on Earth.
