sendPacket had its own idea of what a server response means: any leading `#` counted as harmless chatter. The login parser had just been taught that `# Port full` and `# Login by user not allowed` are refusals - the server announcing it is about to drop us - so the two paths reached opposite conclusions about the same line, and the send path was the optimistic one. Probed across the responses captured from live servers, they disagreed on four of six. classifyAck now shares AprsLogin's judgement. A greeting or keepalive still counts as sent, because APRS-IS does not acknowledge position reports and silence is the normal outcome; anything the server says that is not harmless fails the report. A late login verdict arriving here also counts as sent, since it is not about this packet and the login state already carries it. Two socket tests cover both directions: a `# Port full` after the write fails the report, and a real captured keepalive after the write does not.
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.
