The previous commit listed the refusal wordings it knew - "invalid login" and "login
denied" - and skipped everything else as chatter. That list was incomplete. Probing the
parser against responses captured from live servers found three it missed:
# Login by user not allowed observed on rotate.aprs2.net
# Port full
# Server full
Each was skipped as a keepalive, so the login timed out into Unknown, Unknown is
deliberately read as "may be working", and every send afterwards reported success to an
operator the server had refused. Exactly the failure the previous commit fixed, reached
by a different wording.
Inverted: identification and keepalive comments are recognised positively, and anything
else the server says during login counts as an objection. The trade is that an unforeseen
harmless comment would read as a refusal - but that errs towards reporting failure rather
than claiming success, which is the direction this feature has been wrong in throughout.
The keepalive prefixes come from a live capture rather than guesswork. aprsc repeats its
own identification with a timestamp every twenty seconds:
# aprsc 2.1.21-gbfc2090 25 Aug 2026 16:41:07 GMT T2UK 195.201.15.71:14580
Two tests had invented a `# Tue Aug 25 ...` date line and a `# keepalive N`, neither of
which any server sends. Both now use the captured format.
Also here: the QRZ cookie test in settings goes through the repository instead of
scraping from the UI. It was the last caller of QrzGridClient, which is deleted, and it
built its result from hardcoded Chinese strings inside the composable - those move to
resources, and the four outcomes are now distinguished, where before an expired cookie
and a station with no grid on file produced the same message.
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.
