Cosmovisor アプリ 向け Android 説明
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.
- 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 JPLs 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.
- Night mode: a red theme to preserve your dark adaptation.
PRIVACY
Privacy comes first. No accounts, no ads, no tracking, no telemetry.
- Your GPS location is processed only on the device. It is never sent or stored off-device.
- The only network requests fetch public orbital data (CelesTrak, and optionally the SatNOGS transponder catalog and JPL small-body data). They are anonymous and carry no personal data or location.
- Works offline with the last downloaded data.
Cosmovisor is fully de-Googled: no Google Play Services, no Firebase, no trackers. Location uses the AOSP LocationManager and the fonts are bundled, so it runs on degoogled devices.
