Research presents the development of a telecontrolled antenna rotator system capable of controlling both azimuth and elevation angles through an Android-based application. The system was designed to enhance the effectiveness and efficiency of antenna practicum activities at the State Polytechnic of Malang. The research employed the Research and Development (R&D) methodology, involving several stages: literature study, system design, hardware and software implementation, and performance testing. The rotator mechanism was driven by a Nema 17 stepper motor and controlled by a Raspberry Pi 4 with a DRV8825 driver. The angular position was detected using an AS5600 magnetic sensor, while the Android application communicated with the controller via Firebase Realtime Database for real-time synchronization. Experimental results showed that the rotator achieved 360° rotation with an accuracy of 98.26% for the azimuth axis and 99.16% for the elevation axis. The system remained stable under loads of 500 g and 1 kg, with a maximum deviation of only 2°. These results indicate that the developed system is reliable and suitable for educational use, providing precise control, real-time monitoring, and improved practicality compared to conventional manual methods
