Satellite and Space Communication Technology

Remote sensing is the science of collecting information about the Earth's surface without direct contact, typically using satellites, aircraft, or drones equipped with specialized sensors. These sensors detect and measure reflected or emitted energy—such as visible light, infrared, or radar signals—to analyze landscapes, monitor changes, and support decision-making. Remote sensing plays a vital role in various fields, including agriculture, environmental monitoring, disaster management, urban planning, and climate science. It allows for large-scale, timely, and repeated observations, making it essential for tracking natural resources, detecting changes over time, and responding to global challenges like deforestation, pollution, and climate change.
