WaveLog v1 truncated every grid to four characters with gridsquare.take(4), while v2 sent the same grid at full precision. QRZ backfill provides six-character locators (e.g. OM89ab / FN31pr), so the v1 path - the one used by the user's server in practice - degraded position precision from roughly 4.6 km to around 100 km and stored different data depending on which API version answered. Send the complete grid through v1 as well. The ADIF length field is already computed from the actual value, so six/eight-character locators need no special handling.

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.
