Remote Sensing Satellites

Remote Sensing Satellites

Remote Sensing Satellites are satellites designed to observe, monitor, and collect data about the Earth’s surface and atmosphere from space. Instead of direct contact, they use sensors and imaging technologies to capture information in different wavelengths (visible, infrared, microwave, etc.).

These satellites are vital for studying land, oceans, weather, climate, and natural resources, and they provide data for scientific, environmental, agricultural, and defense applications.
