SAFE-T SDR Design Micro-g (SEMAPHITES)

The SAFE-T SDR Design Micro-g model is an accepted design for the 2024-2025 NASA Micro-g Challenge, featuring an autonomous RF signal detection platform for Orion spacecraft recovery operations.

• Central Processor: Raspberry Pi 5 for data processing.
• SDR: PLUTO+ SDR monitoring 121.65 MHz and 406.025 MHz frequencies.
• Antennas: Two external antennas mounted on a lightweight 60-inch tripod.
• Enclosure: All components are housed in a Pelican 1400 case for reliable water-side operation.
• Display: 7-inch touchscreen for real-time data visualization.
• Software: Python3 for signal demodulation and analysis.

The system design emphasizes simplicity, portability, and durability for rapid deployment in remote or aquatic environments. Its modular layout allows for hardware replacement and software upgrades, enhancing scalability.
