Electronics and Communication Engineering (ECE) in Satellite and Space Communication focuses on the development, deployment, and optimization of technologies that enable reliable communication in space and between Earth and space systems. It is a critical field for global connectivity, navigation, defense, scientific exploration, and monitoring of Earth's resources.
Satellite and Space Communication
- Satellite and space communication refers to the transmission of information using artificial satellites, spacecraft, and ground-based systems. This involves:
- Geostationary (GEO), Medium Earth Orbit (MEO), and Low Earth Orbit (LEO) satellites.
- Relays for data, voice, and video communication across vast distances.
- Communication between space probes, rovers, and mission control.
- Transmission of scientific data during deep space exploration.
- Communication between satellites for collaborative tasks, such as in satellite constellations.
- Ground stations that transmit, receive, and manage satellite signals.
