BRIN Emphasizes the Importance of Precision Control Systems for the Success of Satellite Missions

JAKARTA - The National Research and Innovation Agency (BRIN) emphasizes that a precise and stable satellite control system is needed to support the success of missions in low Earth orbit (LEO).

This stable control system is a determining factor that can make satellites carry out their tasks without obstacles. Communication can also run smoothly without technical interference.

Mohammad Mukhayadi, Assistant Expert Engineer of the BRIN Satellite Technology Research Center, explained that the design of this control system must be carried out from the beginning. That way, the satellite that is launched can remain safe from the extreme space environment.

"Precision control design from the beginning is important to maintain the stability of the satellite in carrying out missions, such as image acquisition and communication," said Mukhayadi, quoted from the BRIN website on Saturday, February 21.

This system is considered superior because it is able to create natural stability through special wheel rotation inside the satellite. This method is proven to be more resistant to external disturbances such as Earth's gravity, magnetic field, to atmospheric obstacles in low orbit.

Another advantage of this system is its ability to overcome internal sensor errors, including drift problems in gyro components. In addition, satellites using this system will be easier to recover if there is a major disturbance due to shocks.

In terms of power efficiency, this system is considered more economical because the star sensor does not need to be active to perform calibration continuously. The angle-based approach also provides higher accuracy compared to methods that only rely on angular velocity alone.

By developing precision control technology, BRIN hopes to increase the reliability of small satellite constellations in the future. This is very important in ensuring communication services work stably, both between satellites and satellite communications to ground stations.
