Satellitplattformar
Satellitplattformar refer to the foundational structure and systems of a satellite. These platforms provide the essential support and services for the payload, which is the part of the satellite that performs its specific mission, such as communication, Earth observation, or scientific research. A typical satellite platform includes a power system, usually consisting of solar panels and batteries, to generate and store electricity. It also incorporates a communication system for transmitting data to and receiving commands from ground stations. A crucial component is the attitude determination and control system, which maintains the satellite's orientation in space. This system often uses sensors like star trackers and gyroscopes, along with actuators such as reaction wheels and thrusters. The thermal control system manages the satellite's temperature, ensuring it operates within acceptable limits in the extreme conditions of space. The platform also houses the command and data handling system, which processes instructions from Earth and manages the satellite's onboard systems and data. Finally, the structure itself provides the physical framework to integrate all these subsystems and the payload. Different types of missions may require specialized platforms, but the core functionality of providing power, control, communication, and structural integrity remains consistent.
