The roaming page was repeatedly rebuilt by hand and the red marker still rendered at the wrong spot on the user's device. Per the user's explicit instruction the whole page is now a faithful, line-by-line port of the reference app (QTH定位器 2.0, com.us1pm.gridsquarelocator) with zero UI or logic changes. UI (res/layout/main.xml, byte-verified via aapt2 dump): - 25dp holo-blue GPS bar: "GPS" 14sp, green/red status dot 15dp (original mipmaps copied as drawables), centered date, right time, translucent-yellow "设置启用GPS" button that opens location settings - Latitude/longitude rows: 16sp black labels, right-aligned decimal values, DMS label format "纬度 22° 18' 50" N" exactly as reference - 43sp bold black locator, centered, with progress spinner + notice - 3x3 continuous grid: 60/200/60dp columns, middle row fixed 205dp, edge cells #0BACF1, center cell 200x200dp holo-blue (#01DDFF as shown on the user's device), center label 100x80dp 30sp bold white (textColorHighlight) centered, bottom "制作：US1PM 汉化：BA7LCE" - Red marker: original pnt.png (red square with white outline), 10x10dp, absolutely positioned by the reference lookup tables (lon 3rd pair a..x -> leftMargin -2..190dp, lat 3rd pair a..x -> topMargin 190..-2dp, screen-Y inverted) Logic (MainActivity.java showLocation/checkEnabled/onResume): - 8-char locator via the reference range-lookup tables - 3x3 neighbor grid via parseInt3 five-branch logic incl. all four corner-carry tables (00/09/99/90) - Live GPS + network updates 10s/10m while the page is shown, provider filtered to gps/network, checkEnabled three-state (green dot / red dot + settings button) exactly like the reference - Time = cached hour prefix + fix minutes; date "dd MMM yyyy" Dropped only the Play-store ad banner (conflicts with GPL project). Verified: 11 unit tests pass (locator, marker lookup, grid, DMS, time, all edge branches); feature + app modules compile. RoamingState.kt removed - state and math now live in RoamingScreen.kt.
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.
