EOS-05 (GISAT-1A) Earth Observation Satellite: GSLV-F17
Why in the news
ISRO scheduled the launch of EOS-05 on a GSLV rocket from Sriharikota; it is an operational follow-up to the GISAT-1 mission that was lost.
Key facts
- Satellite: EOS-05, earlier named GISAT-1A.
- Platform: I-2K.
- Launcher: GSLV-F17 (GSLV Mk II) from the Second Launch Pad, SDSC-SHAR, Sriharikota.
- Orbit: geosynchronous, around 35,786 km.
About the mission
- It provides near-real-time monitoring of India, nearby oceans and border regions.
- The high orbit follows Earth’s rotation, which avoids the multi-day revisit gaps seen with Low Earth Orbit satellites.
- Main aim: continuous spatial, spectral and thermal observation for disaster mitigation, agriculture and strategic defence.
Exam angle
- Rocket: GSLV-F17; launch site: Sriharikota.
- Earlier name: GISAT-1A; bus: I-2K.
- Advantage of geosynchronous orbit: persistent coverage without long revisit gaps.
