mckero 8d88100b15 feat(settings): custom URL now overrides the online-update default source
The "Custom URL" dialog's two URL fields now control the default
source used by the online update, per the user's intent (one-time
setup, no extra steps per update):

- Defaults are real URLs now: TLE = Celestrak "All" (active group
  CSV), transceivers = SatNOGS API. The example.com placeholders are
  gone.
- updateFromRemote(): the "All" TLE entry and the "SatNOGS" entry are
  replaced by the user's URLs when the corresponding custom toggle is
  ON and the URL is non-blank; otherwise the real defaults are used.
  The old "Other" appended-source logic is removed - the toggle now
  means "use my URL for this source" instead of "download an extra
  source". Each source (TLE / transceivers) is independent.
- Each URL field gained a reset (loop) icon button on the right that
  restores the default URL text (new ic_reset drawable, Autorenew
  vector). Strings added in en/zh/tr.

Test updated: custom TLE URL data now lands under the "All" type
instead of "Other". Verified: core:data tests pass, settings + app
compile. Version stays 4.4.8 (覆盖 per user).

Look4Sat: Satellite tracker

Look4Sat CI

Get it on Google Play Get it on F-Droid

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.
