About Cosmovisor

Point your phone at the sky and Cosmovisor overlays the satellites

passing over you right now on the camera image, in augmented reality.

Plus pass predictions, ham-radio tools and a star map.

All the orbital math runs on your device. Works fully offline once the

public orbital data has been downloaded.

FEATURES

* AR view: camera preview with satellites drawn at their real sky

position, refreshed every second. Tap one for its data.

* "Only visible" filter: hides everything you could not actually see

right now, using the satellite's brightness and how dark your sky

is at this hour.

* Satellite list: search by name or NORAD id; filter by category

(ISS, Starlink, GPS, weather, science...), object type

(payload / rocket body / debris), country/operator, orbit regime

(LEO/MEO/GEO/HEO), radio band and "above the horizon now".

* Passes: 24-hour pass predictions grouped by day, with opt-in

alerts before a pass.

* Sky and astronomy: Sun, Moon and planets, Moon calendar, eclipses,

a pannable planetarium, Starlink train finder, and bright comets

and asteroids from JPL's Small-Body Database.

* Ham radio: live full-duplex Doppler (including inverted

transponders), rig and rotor control over TCP (rigctld/rotctld),

ISS SSTV and APRS decoded from the phone mic, RTL-SDR reception

over rtl_tcp (NBFM, SSTV, NOAA APT weather imagery), and a QSO log

with ADIF export. All opt-in.

What's new in 1.0.6

Starlink are no longer treated as spheres: they shine brightest backlit, in twilight, and the "Only visible" filter no longer hides them. New: tell the app how dark your sky is. From the AR legend it shows a star and asks if you see it, and remembers the answer for that place. The sky keeps its shape when you rotate the phone. "Only visible" now has its own row. Optional: brightness from ESA DISCOS object sizes, with brightness updates on.
