IridiumRF-MR: A Multi-Receiver One-Dimensional I/Q Dataset for Specific Emitter Identification of LEO Satellites

IridiumRF-MR is a multi-receiver one-dimensional I/Q dataset collected from Iridium downlink signals using six ADALM-PLUTO software-defined radio receivers. The dataset contains 367,658 valid samples from 66 Iridium satellites. Each sample contains unmodulated-tone, BPSK, and QPSK I/Q segments together with satellite identity, measured Doppler shift, signal-to-noise ratio,acquisition timestamp, receiving-site coordinates, and environmental metadata. The dataset is intended to support individual satellite identification, radio-frequency fingerprinting, receiver-related evaluation, SNR analysis, and input-sequence-length studies.
