AimSat

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, no ads, 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.

PRIVACY

Your location never leaves your device. No accounts, no analytics, no tracking. Orbital data is fetched from CelesTrak and Space-Track; everything else runs offline.
