Point your phone - or your antenna - at any satellite in real time. AimSat gives you live azimuth and elevation for over 50 satellites: the International Space Station, MUOS military UHF birds, WGS broadband relays, amateur AMSAT passes, weather satellites, and more. WHAT IT DOES - Live sky position (azimuth + elevation) updated every second from your GPS - SGP4/SDP4 orbital propagation - the same math NASA uses, running on-device - Antenna alignment mode: hold your phone like a tray, tilt it up, and the crosshair tells you exactly where to point - Pass notifications: get alerted before a satellite rises over your horizon - Garmin watch support: az/el values mirror to your wrist hands-free - Filter by category: ISS, Amateur, Weather, GEO, MUOS, WGS - Pin, hide, and sort satellites to match your workflow - Full ground-track map with sub-satellite point AIMSAT PRO Upgrade once ($2.99) and unlock the 7-day pass planner - see every satellite window for the full week ahead, export passes to your calendar, and plan before you're in the field. No subscription, ever. BUILT FOR OPERATORS Whether you're a ham radio operator chasing FM satellites, a SATCOM technician aligning a terminal, or just someone who wants to wave at the ISS - AimSat has the precision you need without the bloat you don't.
