Overview
The EOS Orbit SDR Transceiver pairs a Linux command and data handling unit with an LMS7002M wideband front end. It tunes continuously from 100 kHz to 3.8 GHz, transmits up to 2 W through the integrated power amplifier, and moves data at up to 1 Mbps with optional LDPC and BCH coding and DVB-S2 framing.
The radio is defined in software. The same hardware ships configured for telemetry and telecommand, high-rate file downlink, or receive-only missions. On LOGSATS-2 the design flew configured as a 1090 MHz ADS-B receiver, collecting aircraft position broadcasts from orbit.
Features
- Continuous tuning, 100 kHz to 3.8 GHz
- BPSK, QPSK, FSK, and GFSK modulation
- Transmit up to 33 dBm (2 W) with PA control
- Receive sensitivity to -95 dBm
- Optional FEC (LDPC + BCH) and DVB-S2 framing
- Quad-core Arm Cortex-A53 CDH running Linux, programmable in C, C++, and Python
- Watchdog, over/under-voltage, ESD, and EMI protection
- Optional PPS input for precise time-tagging
