Opinion split on the stripes, so Settings > Other now has a switch. On by default, since the flat tile it replaced hid intra-day outages, which is the problem the stripes were introduced to solve. Flat mode is deliberately not the old behaviour. The old cell took its colour from the first slot with a report and its count from that same slot, so a day that worked in the morning and failed all afternoon read as "worked" - measured across eight representative day shapes, two of them had their failure hidden outright, and the count reported 1 where the day held 24 reports. Flat mode now takes the day's worst status and the day's total count, so the summary can understate detail but not hide bad news. The help text says so, in case someone turns the switch off expecting the tile they remember. The count is drawn in black or white by relative luminance rather than always white: on the telemetry amber, white measured 1.83:1 against WCAG's 3:1 for large text, and that cell does carry a count whenever a day held nothing but telemetry reports. All six status colours now clear 3:1, the worst being 3.03. SatStatusViewModel collects the setting rather than reading it once - the switch is on another screen, so the operator is always elsewhere when they change it and would otherwise return to the old style. Strings in all nine locales.
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.
