The marker's vertical position was hardcoded (10dp below the label) — markerY never participated, so the dot could only move horizontally and could not reflect where the GPS fix sits inside the 4-char square. Now the marker is positioned in both axes from the cell's top-left corner: - x = markerX * cellWidth, y = markerY * cellHeight (screen Y) - markerX/markerY come from the 3rd character pair via the reference lookup tables (lon a=-2..x=190 as leftMargin; lat a=190..x=-2 as topMargin, i.e. latitude inverted on screen) - Verified numerically against the decompiled tables: a=0/1.0, i=0.333/0.667, x=0.958/0.042 — matching within 3% (the reference table is slightly non-uniform) Label stays at upper-middle (28sp bold); marker is only drawn when a valid locator exists.
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.
