ISRO Satellite Launch Process

Preparation

ISRO engineers prepare the satellite and launch vehicle at the Satish Dhawan Space Centre in Sriharikota, carefully integrating the payload and checking all systems.

Launch Vehicle Assembly

The satellite is mounted atop the PSLV (Polar Satellite Launch Vehicle) or GSLV (Geosynchronous Satellite Launch Vehicle), precisely aligned and secured.

Lift-off

The rocket ignites its powerful engines, generating massive thrust to overcome Earth's gravity. The launch vehicle follows a carefully calculated trajectory.

Space Deployment

Once in the correct orbit, the satellite separates from the launch vehicle and begins its mission, deploying solar panels and communication systems.

Remote Sensing and Geo-informatics

What is Remote Sensing?

Remote sensing is the process of detecting and monitoring physical characteristics of an area by measuring its reflected and emitted radiation at a distance, typically using satellites or aircraft. It enables comprehensive environmental and geographical data collection without direct physical contact.

Key Technologies

Optical Sensors

Capture visible and infrared wavelengths for surface imaging

Radar Imaging

Uses radio waves to create detailed terrain maps

GIS Integration

Combines spatial data for comprehensive analysis

Applications

Environmental monitoring and climate change research
Urban planning and infrastructure development
Agricultural yield prediction
Disaster management and response
Natural resource exploration
