1. Enter Name and Grid Square (Callsign optional).
2. Check When can I receive the ISS? to see the next passes over your station and listen on the downlink frequency.
3. Add the SSTV frames you receive: click a slot, use Add images to select several at once, drag & drop them, or paste them. Drag a frame onto another slot to swap them.
4. Click a frame to see it larger, adjust its reception time, move it or make an SWL card.
5. Upload the official Diploma (optional) and pick a Background.
6. Click Save Mosaic as JPG, or Story format for social media.

Certificate: this tool does not send your images to ARISS. To get the official certificate, upload your images to the ARISS SSTV Gallery. When you receive it, you can add it to your mosaic as the Diploma.

Frames are kept at the native resolution of the SSTV mode (Robot36 320×240, PD120 640×496), so the Decomposer can extract them again. The mode and the number of images are set per event by the ARISS-EA Team and can be overridden in Settings.

Local saving is on by default so your data persists across visits. Use Settings to disable it and Clear all to remove saved data.

Reset to event defaults

This removes locally saved fields, images, reception times, background and diploma for all modes. It won’t delete any files you already downloaded.
