The status grid always drew six day columns, but the AMSAT reports endpoint cannot supply six days for the full catalogue. Measured against the live API: limit=500 -> meta.count=500, covers 4 days (Aug 11..Aug 14) limit=1000 -> meta.count=500, same 4 days (server clamps the limit) hours=336 -> meta.count=500, same 4 days (window size does not help) before/offset/page -> ignored, same 500 newest rows With ~90 catalogued satellites the 500 newest rows only reach about four days back, so the two oldest columns were guaranteed to be uniformly gray. Gray means "no report" in this UI, so the screen asserted nobody reported those days when the truth was that the data was never fetched. Derive the column count from the oldest report actually received, capped at six. On live data that yields four columns labelled Aug 14..Aug 11 instead of six with Aug 10 and Aug 9 blank. The UI already renders whatever days it is given, so no UI change is needed. Also name the request constants and record what was measured about the endpoint, so the 500 is not mistaken for an arbitrary choice that can simply be raised. Note for a future change: the per-satellite form of the endpoint (reports.php?name=...) is not affected by the cap - sampling eight satellites returned 926 rows spanning eight days, i.e. full six-day coverage - but it needs one request per satellite (~0.8 s each, ~68 s for the whole catalogue), so switching to it is a deliberate trade-off rather than a bug fix. :core:data:compileReleaseKotlin, :core:data:testDebugUnitTest and :core:domain:test all BUILD SUCCESSFUL.
Look4Sat: Satellite tracker
Radio satellite tracker and pass predictor for Android, inspired by Gpredict
Track satellite passes with ease!
Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.
Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.
The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.
Main features:
- Predicting satellite positions and passes for up to 10 days
- Showing the list of currently active and upcoming satellite passes
- Showing the active pass progress, polar trajectory and transceivers info
- Showing the satellite positional data, footprint and ground track on the map
- Custom TLE satellite data import is available via Three Line Element .txt files
- Offline first: calculations are made offline. Weekly TLE data update is recommended.
