Two corrections to10c415faand0889a3bd, keeping what those got right and undoing what they cost. The transcript now follows new text through an explicit follow flag rather than comparing scroll position against maxValue. maxValue is written during layout, after the composition that would read it, so the comparison tested the previous frame's height: following fell progressively short of the true bottom and, once the gap passed the slack, latched the operator out of follow-mode until they hit the exact end. Scrolling away still stops it, which is the point. The AMSAT day cell goes back to 28 dp. Raising it to 48 dp for the minimum touch target measured a 71% increase in row pitch - 14 satellites per screen down to 8 on a 6.1" phone - and comparing many satellites at a glance is what that page is for. Compose cannot extend a touch target past the layout bounds, so this is a choice rather than a fix; 28 dp is also what shipped before, so the regression was mine. The contentDescription added alongside it stays, since it costs nothing.
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.
