Satellite Attitude Control Block Diagram

Satellite Attitude Control Internal Structure

This internal block diagram shows the main parts inside a small imaging satellite and the connectors that matter at system level. Solar power reaches the power subsystem, which feeds the spacecraft data bus. The bus connects the attitude-control computer, imaging payload, radio and thermal control. The attitude-control loop is explicit: sun and star sensors plus the gyroscope provide measurements to the ADCS computer, and the computer commands the reaction wheels. Ground commands arrive through the radio, while the payload has both data-bus and thermal interfaces. Use it to discuss allocation of functions to parts before specifying detailed electrical connectors or software messages.

“A satellite attitude-control internal block diagram with a power subsystem and spacecraft data bus feeding an ADCS computer, imaging payload, radio transceiver and thermal control; sun and star sensors and a gyroscope feed the ADCS computer, which drives reaction wheels; ground commands enter through the radio and solar power feeds the power subsystem.”

接著試試Add a GPS receiver to the data busConnect the payload to the radio for image downlink

這張圖裡有什麼

看懂背後的決策。

01Central bus

Shows the shared connection between spacecraft subsystems.

02Closed attitude loop

Links sensors, ADCS computer and reaction wheels.

03Payload interfaces

Makes power, command and downlink dependencies visible.

Use this as an internal block view when defining spacecraft parts and the interfaces between them.

常見問題

What does the ADCS computer do?

It estimates attitude from sensor data and commands actuators such as reaction wheels.

Why show a data bus?

It identifies the shared interface through which onboard subsystems exchange commands and data.

Is this a wiring diagram?

No. It shows system parts and interfaces, not pin-level wiring or cable routing.
