Onboard Computer

Onboard computer is the central processing unit (CPU) and associated hardware that control and manage a satellite’s operations. It serves as the brain of the satellite, performing essential tasks to ensure proper functioning and efficient operation. It is designed to handle various functions, including data processing, system control, communication, navigation, and payload operations.

At the heart of the onboard computer is the central processing unit (CPU), which is responsible for executing instructions and performing calculations. The CPU is supported by other hardware components, such as memory modules (RAM and ROM), input/output interfaces, sensors, and actuators.

The onboard computer plays a critical role in managing the satellite’s subsystems and coordinating their interactions. It handles data acquisition from onboard sensors, processes the collected data, and makes decisions based on predefined algorithms and commands stored in the onboard software.
