Satelliittibusi

Satelliittibusi, or satellite bus, refers to the structural and functional framework of a satellite, excluding its payload. It serves as the backbone of the satellite, providing the necessary support and infrastructure for the payload to operate effectively. The bus typically includes subsystems such as power, thermal control, attitude and orbit control, and communication systems.

The design of a satellite bus is crucial for the overall performance and longevity of the satellite. It must be robust enough to withstand the harsh conditions of space, including extreme temperatures, radiation, and micro-meteoroid impacts. The bus also plays a vital role in managing the satellite's power requirements, ensuring that the payload receives the necessary energy to function.

There are various types of satellite buses, each designed to meet specific mission requirements. For instance, small satellite buses are optimized for cost-effective launches and are often used for educational or experimental missions. Conversely, large satellite buses are designed for high-power payloads and are used for communications, Earth observation, and scientific missions.

The satellite bus is a critical component of any space mission, as it directly impacts the satellite's operational capabilities and lifespan. Advances in satellite bus technology continue to drive innovation in space exploration and satellite-based services.
