VirtualIORS: ARISS Emulator

VirtualIORS is an open-source Android application developed by the ARISS-EA team to emulate the ARISS IORS payload used aboard the International Space Station.

Prepare realistic ISS-style amateur radio demonstrations using SSTV images, optional voice announcements and APRS packets. The app is designed for educational activities, classroom demonstrations, outreach events and amateur radio experimentation.

MAIN FEATURES

• Create SSTV transmissions from audio files, image files or automatic camera captures.
• Generate Robot36 and PD120 SSTV audio directly on the device.
• Add an optional callsign, image counter or UTC timestamp to transmitted images.
• Play voice announcements using on-device text-to-speech or a custom audio file.
• Generate APRS beacon, GPS position, telemetry and short text packets using AX.25 and Bell 202 AFSK.
• Choose sequential or shuffled playback and configure intervals between transmissions.
• Enable a VOX preamble for compatible radio interfaces.
• Save and load named presets.
• Try built-in Robot36, PD120 and APRS demonstrations.
• View the current signal, the next item and the remaining transmission time.

PRIVACY

VirtualIORS works locally. Selected images and audio remain on the device. Camera access is requested only when the automatic camera feature is used, and location access is requested only when APRS GPS position is enabled.

IMPORTANT SAFETY INFORMATION

Very short intervals between SSTV images may overheat or damage some RF transmitters. VirtualIORS displays a warning when the configured cooldown may be unsafe. Use appropriate audio levels and always follow local amateur radio regulations.

VirtualIORS requires Android 9 or later.
