About
The BusCORE Satellite RF Terminal is a dual cold-redundant radiocommunication infrastructure with 2 MB MRAM data buffer storage each, 2x UART accessible over 2 combined ports. It achieves excellent data throughput using dedicated hardware radio implementation optimized for long-range, high-data-rate communication links, exceeding legacy amateur radio link systems by 6-10 dB better link margins and micro-delay RX/TX switching times. Data frames are protected using CRC checks, with telemetry messaging, uptime, packet counters, and RSSI/noise floor measurements at the antenna port. Time-of-flight ranging with 65,000 addresses allows multinode operations aboard a swarm of satellites, each accessible individually. The unit provides variable data rates from 1200 bps up to 38,400 bps depending on link quality, with automatic bitrate fallback to a nominal 4800 bps setting optimized for LEO operations.
