Description
IridiScope

A native Windows application for receiving, decoding and visualising Iridium satellite signals. Load an IQ recording or plug in an SDR, and IridiScope shows a live spectrum and waterfall, demodulates Iridium bursts, parses the messages, decodes voice calls, reassembles ACARS/SBD traffic, and plots the satellites on a world map.


Features

Live spectrum + scrolling waterfall with configurable FFT size and averaging.
Full Iridium burst detection, DQPSK demodulation and native message parser (IRA, IBC, IDA, IMS, ITL, SY, IP, VO).
Satellite tracking and ring-alert positions on an equirectangular world map.
Voice call capture with in-app playback, plus ACARS/SBD message decoding.
Sources: IQ file, SDRplay, HackRF and Airspy (all locked to the Iridium band at 1623.326935 MHz), with gain and bias-tee controls.
Automatic update notifications.
