It is related to the rods. 5 Previous Technique Satellites are exposed to mild but constant disruptive torques and forces. These forces remain. These forces need to be constantly balanced. Located on the satellite... For many pieces of equipment in the field to perform their tasks, the satellite's orientation plays a crucial role. It plays a role. Therefore, attitude determination and control systems (ADCS) are used in satellites. It plays a significant role in the operational success and is a crucial subsystem of the satellite. These systems consist of sensors and components, each using different physical principles. It includes a combination of actuators. ADCS sensors, in particular horizon sensors, These can include a range of components such as star trackers, solar sensors, and magnetometers, and To ensure accuracy and redundancy, it is often necessary to use more than one sensor simultaneously. 15 is preferred. In contrast, ADCS actuators use reaction wheels and magnetic torque rods. It may include. Magnetic torque bars are designed to carry the current capable of generating the desired magnetic moment. It includes a coil that is regulated. Magnetic torque rods are mounted on the satellite. and the interaction between their own magnetic moments and the Earth's magnetic field, a 20 on the satellite It generates torque. Thus, by controlling the resultant magnetic moment of the torque rod system, The satellite's angular momentum and, in some applications, its orientation can also be controlled. The magnetic field created by the magnetic torque bar turns on the current passing through the coils. It is controlled by shutting it down. One of the applications included in the known state of the art is shown in Figure 1, and this 25 In practice, there are multiple torque rods, each located in a different region of the satellite. (T1, T2, T3) are driven by a single driver card (K). The driver card (K) controls the satellite. The orientation determination and control system (A) is located on or near the orientation It is connected to the identification and control system (A). The driver board (K) is an electrical component contained within the satellite. It is connected to the power system (E) and receives signals from the orientation and control system (A). evaluating the power signals coming from the electric power system (E) in line with this signal. converting them into supply signals for each torque bar (T1, T2, T3) and sending them to the torque bars (T1, The supply signal is transmitted between the driver board (K) and the torque rod (T1, T2, T3). 29FM / TR 2 This is provided by connecting cables located between them. The torque is transmitted to the torque rods (T1, T2, T3). The supply signals are analog, variable power signals; they have a square wave-like form and Therefore, this signal, especially its corner points, can emit at high frequencies. Torque Transmitting the feed signal over a long distance can lead to noise generation in the system, and this Therefore, it can also lead to various systemic errors. In addition, 5 The supply signal from the driver board (K) is transmitted through the connecting cables to the torque rod (T1, T2, T3) are lost during the transmission process. Therefore, in this system, the coil No clear data is available regarding the current passing through it. Another known application involves an independent drive. However, this drive provides torque. It is located near, not on, the rod. This means that the driver electronics are located near the satellite 10. This causes it to take up additional space and the connection between the torque rod and the driver. This requires the cable to be secured to the satellite. In this application, the driver Although the torque rod supply signal from the electronics is transmitted over a shorter distance. Solutions cannot be provided to the disadvantages mentioned above.
