Full interface in English, العربية, Español, Français, Deutsch, 日本語, 中文, Português, Русский, and Italiano. Arabic flips RTL on translatable pages; ham-radio terms (callsign, AOS, LOS, SSTV, ADIF, NORAD, APRS…) stay English so exports stay compatible.
Track ISS and 100+ amateur satellites with live icons on an interactive map. The May 2026 catalogue refresh added ten birds including MESAT-1 (MO-122), OOV-Cube, and the Russian Geoscan family (RS47S / RS60S / RS67S / RS81S / RS82S / RS39S / RS51S). Always know where they are.
Detailed AOS, LOS, duration, azimuth, and elevation data. Never miss a good pass again.
Visualize multiple passes in easy-to-read tables. Plan your satellite operations efficiently.
Get alerts for upcoming passes. Add to calendar and share with your team.
Save contacts to your local database. Filter, search, export, and email your QSO list. Pick a satellite from the dropdown and TX/RX band + frequency + mode auto-fill from a built-in catalogue of 100+ amateur sats. Tiangong (CSS) frequencies corrected in v4.5.0+45 — it's a V/u inverting SSB linear transponder per AMSAT-UK, not the FM repeater earlier catalogues showed.
Display saved QTH and current locations on interactive maps. Track your grid squares.
Decode Slow Scan Television images from audio recordings. Supports Robot 36/72, Scottie, Martin, and PD modes with manual Shift / Slant / Start controls.
Record audio directly from the AR tracking page during live passes — SSTV, SSDV, Digital, Weather, and Music. Short-name filename convention (callsign_mode_date_time_freq.wav) so files are self-documenting.
Augmented-reality satellite tracking with device sensors plus a dedicated compass dialog for pass visualization. Export the compass view as a themed image with watermark.
Track Meteor-M N2-3 and N2-4 on 137.900 MHz LRPT. “Purple mode” applies universal VHF Doppler and records session audio for post-processing with external SDR software.
Listen to short music tones broadcast by satellites that use a melody instead of CW Morse as their unique RF identifier — classical compositions, video-game themes, even Beethoven’s “Ode to Joy”. Brown-tinted RX-only mode on UHF 400–402 MHz, ideal for SDR listeners. Includes BALKAN-1, Flamingo-1, OTP-2, and T.MicroSat-1.
Read-only APRS-IS TCP layer for your own beacons + nearby APRS rigs. Age-fading track polylines behind moving stations, 40+ APRS-symbol → Material-icon mapping, SSID filter chips (-9 / -13 / -11 / Other) docked above the bottom nav, bulletins feed, smart YOU-hide when a tracked station overlaps your position, tap-to-select details panel with bearing & distance, heard-by iGate attribution via aprs.fi. Dedicated APRS callsign keeps SSIDs out of your QSO log. v4.5.0+45 hardened the lifecycle — toggle OFF then ON reloads stations immediately and tab-switching mid-connection no longer leaves zombie timers.
Schedule frequency-override windows for satellites that occasionally drift from their primary frequency — covers SSTV, SSDV, Digital (APRS / digipeater), and Weather (Meteor-M N2-3 / N2-4 137.900 ↔ 137.100 MHz rotation). Pick service type + satellite + date range + frequency; AR page auto-switches when an event is active and falls back to the default outside it. Music broadcasts are excluded — their frequency is the unique identifier.
Every prediction card and notification card carries a small dot showing real-world activity from the AMSAT Live OSCAR Satellite Status page over the last 24 hours UTC. The dot uses the AMSAT cell palette directly so it mirrors what you see on amsat.org: blue = Active (heard), purple = ISS Crew Voice, amber = Telemetry/Beacon only, orange = Conflicting reports (small “?” overlay), magenta = No-signal reported, grey = no reports. Hollow ring means AMSAT does not track the bird. Tap the dot for a themed popup: 48-hour strip, dates header on top, services stacked on the left, individual reports per cell (callsign + grid + 15-min UTC slot, with × dismiss), and a compact share-image button. AMSAT-tracked modes with no recent reports are listed as a footer (“No reports in last 6 days: SSDV, VHF Digi”), so the absence of a row is never silent. Same compact share is also available on the (i) Pass Info popup — what you see in the popup, including the cell-detail panel if open, is what you share. 15-minute refresh while a prediction page is open; silent background retry on errors. Read-only consumption with full attribution — we do not submit reports.
Per-QSO themed PNG QSL card, code-rendered (no bundled artwork), theme-aware. Includes your callsign, grid, and contact details. Share or save to Photos.
100 rotating contextual hints covering every feature — shuffle-deck delivery, ≤ 2 per week, 3-day gap. Toggle off anytime in Settings.
iOS, Android, macOS, Windows, Linux, Web. One app, one log, everywhere you go. Dark / light theme everywhere.
Yousuf AL Balushi (A46UNX) started his Ham Radio journey in November 2024 as an official member of The Royal Omani Amateur Radio Society (ROARS), and quickly became passionate about satellite hunting.
After experimenting with various tracking apps and finding them lacking, he decided to build something better. Ham Satting combines all the essential tools into one powerful, multi-platform application.
