Ek Satellite Jo Kabhi 'Move' Nahi Karta

Zyada tar satellites Prithvi ke charon taraf ghoomte hue dikhte hain. Lekin geostationary orbit mein rakhe gaye satellites ek khaas trick karte hain — wo Prithvi ki hi rotation speed se ghoomte hain, jisse relative se wo hamesha ek hi jagah 'khade' rehte hain, jaise koi CCTV camera ek hi fixed cheez ko dekh raha ho, chahe Prithvi khud spin kar rahi ho. INSAT-3DS bhi isi tarah ka satellite hai.

INSAT-3DS Kya Hai

INSAT-3DS ko ISRO ne 17 February 2024 ko GSLV-F14 rocket se Sriharikota (Andhra Pradesh) se launch kiya tha. Ye 2,274 kg ka satellite ISRO aur Ministry of Earth Sciences (MoES) ka joint mission hai, aur ye INSAT series ke pehle se maujood INSAT-3D aur INSAT-3DR satellites ke saath milkar kaam karta hai.

Ye Kaise Dekhta Hai Mausam Ko

Satellite mein do main instruments hain — ek 6-channel Imager aur ek 19-channel Sounder. Ye milkar clouds, ocean surface temperature, aur atmosphere ke different layers ka data continuously collect karte hain. Kyunki satellite ek hi region (India aur aas-paas ka Indian Ocean) ke upar fixed rehta hai, ye us area ko lagatar, real-time mein monitor kar sakta hai — jo cyclone jaise fast-changing events ke liye bahut zaroori hai.

Disaster Warning Mein Iska Role

Satellite mein ek Data Relay Transponder (DRT) hai jo desh bhar mein lage automatic weather stations se data collect karta hai. Iske alawa ek Satellite-Aided Search & Rescue (SAS&R) transponder bhi hai — jab kisi ship, aircraft, ya trekker ka emergency beacon activate hota hai, ye transponder us distress signal ko turant relay karke rescue agencies tak pahuncha deta hai.

Cyclone Ke Time Ye Kaam Kaise Aata Hai

Kyunki satellite continuously ek hi region ko dekhta rehta hai, cyclone banne ki shuruaat se lekar uske path aur intensity tak — sab kuch real-time mein track hota rehta hai. Yahi data India Meteorological Department (IMD) ko milta hai, jo isse use karke advance warnings issue karta hai — jitna jaldi warning milegi, utna zyada time logon ko safe jagah move hone ke liye milega.

Aam Aadmi Ke Liye Iska Matlab

Jab bhi phone par cyclone alert ya IMD ka rainfall forecast aata hai, uske peeche aksar isi tarah ke geostationary satellites ka data hota hai. Ye technology kisi lab tak simit nahi hai — ye directly logon ki safety, kisano ki fasal planning, aur roz ke mausam ke poorvanuman se juda hai.
