ISRO successfully launches GSLV-F17 with EOS-05 satellite, from Satish Dhawan Space Centre: Highlights
ISRO successfully launched the GSLV-F17 at 2:55AM IST and reached the geosynchronous orbit with the EOS-0 Earth observation satellite, marking another important mission for India’s space programme. The launch took place from the Satish Dhawan Space Centre, and the mission took a total of 18 minutes.

ISRO pulled off another big win by launching the GSLV-F17 with the EOS-05 Earth observation satellite on board. The rocket lifted off from the Satish Dhawan Space Centre, Sriharikota (Andhra Pradesh), on September 4 at 2:55 AM IST. The goal of the mission was straight and simple-- to get the EOS-05 satellite into its planned orbit so it can start gathering data for Earth observation projects by taking pictures every 5 minutes. This indeed is another strong step towards the advancement of technology and India’s space ambitions.
Here are the highlights for the launch:

EOS-05 satellite to deliver high-frequency earth observation in every 5-minutes
The satellite has been designed to capture images of the Earth at 5-minute intervals from its high-altitude orbit, enabling more frequent monitoring of India's geographical territory. According to reports, it can capture and transmit images covering the country in around 30 minutes, which could significantly strengthen capabilities in earth observation, disaster management and strategic surveillance.

ISRO's GSLV-F17/EOS-05 to become India's new "Eye in the Sky"
ISRO’s GSLV-F17 is launching EOS-05, which is about to become India’s new “Eye in the Sky.” This satellite will be parked in geosynchronous orbit, roughly 36,000 kilometres above us.
What sets EOS-05 apart is not just its position but also its speed. This thing can snap high-frequency images, revisiting the same location every five minutes. In just half an hour, it will be able to scan most of India. When you need quick updates – like in the middle of floods, cyclones, or wildfires – that fast, wide coverage turns raw data into truly useful information.

EOS-05 is a cutting-edge Earth observation satellite from ISRO
EOS-05 is set to be India's first imaging satellite sitting in geosynchronous orbit. Most Earth observation satellites circle the planet in low orbits, snapping pictures of different areas as they swoop by.
EOS-05, on the other hand, stays fixed over one spot for a long time. That means it can keep a constant watch on the same region, which is a huge advantage for monitoring weather, tracking natural disasters, and handling all kinds of real-time applications.
