Satellite Technology

Satellite technology is a crucial component of space technology. Satellites are used for a variety of purposes, including communication, weather monitoring, navigation, and Earth observation. They are launched into space using rockets and are placed in specific orbits depending on their intended function. The design and development of satellites involve a range of specialized fields, including astrodynamics, propulsion systems, and telecommunications.

Spacecraft Design and Development

The design and development of spacecraft involve numerous complex and interrelated processes. These include the design of the spacecraft's structure, propulsion system, power system, thermal control system, and payload. The spacecraft must be designed to withstand the harsh conditions of space, including extreme temperatures, vacuum conditions, and radiation.
