ISRO GSLV Mission to Launch INSAT-3DS

ISRO GSLV Mission to Launch INSAT-3DS Weather Satellite

The Indian Space Research Organization (ISRO) is set to launch the advanced INSAT-3DS meteorological observation satellite on 17th February 2023 from Satish Dhawan Space Centre, Sriharikota using a Geosynchronous Satellite Launch Vehicle (GSLV) rocket. The mission aims to place INSAT 3DS at into a geo synchronous transfer orbit.

 




About INSAT-3DS

INSAT-3Ds satellite is a follow-on mission of Third Generation Meteorological satellite from Geo stationary orbit. It is the latest satellite in India’s advanced INSAT-3D series designed for weather monitoring, forecasting and disaster warnings from geostationary orbit. It carries optical imaging and atmospheric sounding payloads providing meteorological data to aid weather predictions.

 

GSLV Rocket Launch Vehicle

The rocket chosen to carry the 2,268 kg INSAT-3DS to geosynchronous transfer orbit is ISRO’s heavy-lift GSLV Mk II variant that has Cryogenic Upper Stage with indigenous high thrust cryogenic engine providing higher payload capacity. The rocket has been dubbed as the “Naughty boy”. It will be the rocket’s 16th mission overall and its 10th flight using the indigenously developed cryogenic engine.

 

GSLV Mk II Capability

Having previously launched advanced communications satellites like GSAT-7A (2018) and geo imaging satellite GISAT-1 (2021), the GSLV is capable of placing 2.5-ton class spacecraft in intended orbits. Out of 5 prior launches in Mk II configuration, 4 have been successful highlights its reliability.

 

Significance of GSLV Rockets

The GSLVs play crucial role in self-reliant launch capability for deploying advanced Indian satellites without dependence on overseas launchers, saving time and cost overheads. SUCCESS designates indigenous cryogenic engine prototypes over earlier Russian sourced stages.

 

Naughty Boy Rocket

The spacecraft has been dubbed the “naughty boy” of the Indian space programmer by a former chairman of the ISRO. The GSLV holds a failure rate of 40 per cent. Out of its total 15 space missions till date, GSLV F14 has faced problems in six of them. The last mission involving this spacecraft was in May 2023, which was a success, but the one before that had failed.

 

Objectives of the Mission

The INSAT-3DS aims to supplement data from operational satellites INSAT-3D and INSAT-3DR already monitoring weather patterns and enabling accurate cyclone predictions as part of Indian National Satellite System. Its imagery helps in disaster management. The objective of the mission is to monitor the earth’s surface and carry out Oceanic observations and the environment in various spectral channels of meteorological significance.

 

The mission will figure out various meteorological parameters of the atmosphere and provide data on important aspects related to weather and satellite aided search and rescue services.

Banking Norms

 What is IFSC ? IFSC stands for Indian Financial System Code. It is a 11-digit alpha-numeric code that uniquely identifies a bank branch participating in any RBI regulated funds transfer system. The IFSC code helps to transfer money using RTGS, NEFT or IMPS method. The first 4 digits of the IFSC represent the bank and last 6 characters represent the branch. The 5th character is zero.   What is MICR ? MICR is an acronym for Magnetic Ink Character Recognition which is a technology used in the banking industry in printing the MICR codes. A MICR code is a 9-digit code that uniquely identifies a bank and a branch participating in an Electronic Clearing System (ECS). The first 3 digit of the code represents the city code, the middle ones represent the bank code and last 3 represents the branch code. One can locate the MICR code at the bottom of a cheque leaf, next to the cheque number. It is also normally printed on the first page of a bank savings account passbook.   What is t...

What is KYC - Meaning, Types, and Importance

Since 2004, the Reserve Bank of India made it compulsory for all Indian financial institutions to verify both the identity and address of all customers carrying out financial transactions with them. Thus, the KYC process was introduced by the RBI as the only mode of verification.   What is KYC? KYC means to ‘know your customer’ which is an effective way for an institution to confirm and thereby verify the authenticity of a customer. For this, the customer is required to submit all KYC documentation before investing in various instruments. All financial institutions are mandated by the RBI to do the KYC process for all customers before giving them the right to carry out any financial transactions. Whether the customer uses KYC online verification or opts for offline KYC, this is a simple one-time process.   The significance of KYC KYC is an important tool as it looks after the financial bodies and keeps illegal activities in check. Many non-individual customers use financial se...
