The Indian Space Research Organisation (ISRO) successfully launched its advanced meteorological satellite, INSAT-3DS, this past Saturday. This satellite serves as the next-generation successor to the Third Generation Meteorological Satellite.
The mission, designated GSLV-F14/INSAT-3DS, is notable for being entirely financed by the Ministry of Earth Sciences. This launch marks a significant step forward in India’s weather monitoring and forecasting capabilities, with the new satellite expected to enhance the country’s meteorological services and disaster management efforts.
ISRO 16th Mission
In its 16th mission, the Geosynchronous Satellite Launch Vehicle (GSLV) is tasked with launching the INSAT-3DS meteorological satellite into the Geosynchronous Transfer Orbit (GTO). This initial orbit is a transitional phase that allows the satellite to reach a point where its orbit matches the rotation of the Earth.
Following the deployment into GTO, the satellite will undergo a series of orbit-raising manoeuvres. These manoeuvres involve firing its onboard propulsion system at specific times and angles to increase its altitude and adjust its orbit parameters gradually. Ultimately, these manoeuvres will ensure that the satellite reaches and maintains a Geostationary Orbit (GEO), where it appears to remain fixed relative to a specific point on Earth’s surface.
This GEO positioning is crucial for meteorological satellites like INSAT-3DS, as it allows them to continuously observe the same region of the Earth, enabling consistent and comprehensive monitoring of weather patterns and phenomena.
The INSAT-3DS Satellite of ISRO represents a continuation of India’s efforts in meteorological satellite technology, following the Third Generation Meteorological Satellite, operating from Geostationary Orbit.
Funded entirely by the Ministry of Earth Sciences (MoES), this mission is geared towards advancing meteorological observations and monitoring capabilities over both land and ocean surfaces. Its primary objectives include bolstering weather forecasting accuracy and facilitating disaster warnings.
Indian industries have played a significant role in the development and construction of the satellite, showcasing the nation’s growing prowess in space technology.
How will it be Helpful?
Upon completion, the satellite will complement the existing INSAT-3D and INSAT-3DR satellites of ISRO, further enhancing the capabilities of India’s meteorological services.
Multiple departments under the Ministry of Earth Sciences, including the India Meteorology Department (IMD), National Centre for Medium-Range Weather Forecasting (NCMRWF), Indian Institute of Tropical Meteorology (IITM), National Institute of Ocean Technology (NIOT), Indian National Center for Ocean Information Services (INCOIS), along with other agencies and institutes, will utilize data from INSAT-3DS to deliver improved weather forecasts and meteorological services to the nation.
