Two things about the mode on the logging surface. It was held in `remember` with no key, so switching transponder mid-session kept the mode from the transponder before it. The operator saw the old value in the field and it went out with the upload - a wrong mode nobody chose. It is now keyed on the transponder uuid. It was also a text field the operator had to look at on every contact, when the value comes from the transponder record anyway. A pass lasts eight minutes; the study on satellite logging is blunt that the fast surface should carry one typed field, not two. The mode is now shown as a row and the field appears when the row is tapped, because a transponder record can be wrong and the operator still has to be able to say so. The row is 48dp tall, which is the Material Design minimum for anything tappable. Vertical padding alone had left it around 20dp - visually fine, awkward to hit, and a real problem for anyone with reduced dexterity.
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.
