mckero 1e24673632 fix(network): close sockets on setup failure and on write failure
Two leaks in NetworkReporter, the same family as the Bluetooth/APRS/radio
socket leaks fixed earlier:

1. ensureRotatorConnected/ensureFrequencyConnected assigned the field directly,
   so a channel that opened but threw during the rest of setup was never
   closed and remained referenced. Use a local `opened` and close it in the
   catch, matching the pattern used in AprsIsClient/Ic705Controller/
   Ft817Controller/BluetoothReporter.

2. write() only flipped connected=false on failure. The broken channel stayed
   in the field, the next ensure* reconnected and overwrote it, and the old
   channel was never closed. Now a failed write closes the channel and nulls
   the field. The null check is identity-based (socket === field) so a stale
   reference from a concurrent report can never close a newer channel.

State-machine probe: normal write keeps the socket, failed write closes and
nulls, next report reconnects fresh, and passing a stale reference does not
close the newer socket.

Look4Sat: Satellite tracker

Look4Sat CI

Get it on Google Play Get it on F-Droid

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.
