Two defects in how the data source settings were read. The switch reported a state nobody had chosen. `useCustomTLE` was ANDed with `tleUrl != Sources.defaultTleUrl`, so an operator who enabled custom sources and then typed the default URL by hand saw the switch flip itself off. It now reports what they set. The example.com placeholder rewrite ran on every read. A 4.4.7-era build could persist `https://example.com/tle.txt`, and the fix for that rewrote the value each time it was read - so the stored value and the returned value disagreed indefinitely and nothing ever settled it. It is now a one-time migration following migrateRCFormats, which writes the correction back and records that it has run. Not addressed here, and the reason the settings screen still misleads: a custom TLE URL replaces only the source keyed "All" and the other 27 hardcoded sources are still fetched unconditionally, so "use custom sources" actually means "my source plus 27 others". Which way that should go is a decision about intent rather than a defect to patch, and upstream fetches all of its sources unconditionally, which is where the behaviour came from.
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.
