India Successfully Launched Advanced Weather Satellite INSAT 3D

INSAT 3D, the advanced meteorological satellite of India was launched successfully by the European rocket, Arianespace’s Ariane 5 rocket, from the spaceport of Kourou in French Guiana on 26th July, 2013. The satellite will give a push to the weather forecasting as well as help in facilitating disaster warning services.

Arianespace’s Ariane 5 rocket of European space consortium launched the Alphasat satellites as well as INSAT 3D. Alphasat is the largest – ever telecommunication satellite of Europe. This satellite is the result of large – scale public – private partnership between Inmarsat as well as European Space Agency.

INSAT 3D Weather Satellite Features

i. The new satellite, INSAT 3D will be operational for next seven years, i.e., up to 2020.

ii. The aim of the satellite is to make a crucial difference to the disaster warning systems as well as weather forecasting of India.

iii. INSAT 3D will also provide monitoring of the ocean as well as land areas, apart from providing meteorological observation.

iv. INSAT 3D will facilitate new dimension to the weather monitoring because of its atmospheric sounding system.

v. The atmospheric sounding system provides the vertical profiles of integrated ozone, humidity as well as temperature, from top of the atmosphere.

vi. It is important to note that the imaging system and mechanism of INSAT 3D has a lot of improvement in comparison to INSAT 3A as well as Kalpana.

vii. The satellite has the lift – off mass of 2060 kg. It will facilitate continuity to the previous missions as well as also help in increasing the capability of providing meteorological and search and rescue services.

viii. INSAT 3D carries the newly developed 19 channel sounder, which is the first payload of this kind to be flown to the ISRO satellite mission.

ix. INSAT 3D has the facility of Search and Rescue payload which catches as well as relays the alert signals that originate from distress signal of maritime, aviation and land based users to the Indian Mission Control Centre located at ISRO Telemetry, Tracking and Command Network in Bangalore.

Users of INSAT 3D Satellite Signals

The primary users of the Satellite Aided Search and Rescue service in India include Directorate General of Shipping, Defence Services, fishermen, Indian Coast Guard as well as Airports Authority of India.

The alert services include a wide area of Indian Ocean region, as well as covers Sri Lanka, Tanzania, India, Bangladesh, Nepal, Seychelles, Bhutan and Maldives.

The information of oceanographic, hydrological as well as meteorological data from the uninhabited locations over the coverage area from Data Collection Platforms ( DCPs ) such as Agro Met Stations, Automatic Rain Gauge and Automatic Weather Station, as well as remote locations will be collected by the Data Relay Transponder ( DRT ).

The ISRO as well as India Meteorological Department have already established over 1800 DCPs.
