Prototype On-Board Computer Satelit NEI Badan Riset dan Inovasi Nasional Berbasis STM32H753VIT6

Abstract

Prototype On Board Computer (OBC) berbasis mikrokontroler STM32H753VIT6 dikembangkan sebagai solusi pusat kendali untuk satelit mikro Badan Riset dan Inovasi Nasional (BRIN). Kebutuhan sistem yang stabil, modular, dan efisien daya untuk Satelit Nusantara Equatorial IoT (NEI) menjadi landasan pengembangan OBC yang berfungsi melakukan pengelolaan subsistem untuk misi peringatan dini bencana dan pemantauan maritim. Penelitian ini bertujuan untuk merancang, mengimplementasikan, dan memvalidasi sistem yang mampu mengakuisisi data sensor kesehatan (housekeeping) serta menyimpannya ke media eksternal. Metode penelitian menggunakan pendekatan prototype yang mencakup perancangan skematik, layout Printed Circuit Board (PCB), dan pengembangan firmware untuk mengintegrasikan fungsi pengukuran suhu dan daya. Hasil pengujian menunjukkan bahwa prototype OBC mampu berfungsi dengan baik dalam mengakses data sensor secara konsisten, mencatat data ke media penyimpanan, dan mendukung operasional dasar satelit mikro BRIN

The microcontroller based On-Board Computer (OBC) prototype was developed STM32H753VIT6 as a control center solution for microsatellites of the National Research and Innovation Agency (BRIN). The need for a stable, modular, and power-efficient system for the Equatorial Archipelago IoT (NEI) Satellite is the foundation for the development of OBC which functions to manage subsystems for disaster early warning and maritime monitoring missions. This research aims to design, implement, and validate a system that is able to acquire health sensor data (housekeeping) and store it to external media. The research method uses a prototype approach that includes schematic design, Printed Circuit Board (PCB) layout, and firmware development to integrate temperature and power measurement functions. The test results showed that the OBC prototype was able to function well in accessing sensor data consistently, recording data to storage media, and supporting the basic operations of BRIN's micro satellites
