The API caps at 500 records regardless of the hours requested. With 88 catalog satellites, eight of them more active than 50 reports per 72 hours, quieter satellites get crowded out. Measured live: the global pull returned 500 reports covering 36 satellites, while the summary endpoint reported 743 reports across 38 satellites. 26 of 38 satellites had incomplete data, and two (PO-101_[FM] and TEVEL2-6_[FM]) had zero reports in the global pull despite having reports in the summary. The summary endpoint (api/v1/summary.php) returns per-satellite report counts in one request, so the fix adds one extra call rather than the 88-request alternative of per-satellite pulls. A satellite whose global pull is incomplete gets a subdued "68 / 116" marker next to its name, telling the operator the page knows there is more data it could not fetch. The marker is silent when the summary is unavailable or the counts match, so the feature degrades gracefully. The earlier no-data grey (0xFFE8E8E8) already prevented the worst case: slots crowded out of the global pull were marked as "we never looked" rather than claiming "nobody reported". The marker now closes the remaining gap: the page can honestly say "we know there are 116 reports for this satellite but we could only show you 68 of them". Also fixed a subagent mutation-testing residue: the coverage floor had been moved from global (reports.minOfOrNull) to per-satellite (satReports.minOfOrNull) and left in the tree. One test caught it (coverage is judged from all reports, not one satellite's), proving the test has teeth. Adds getAmSatSummary to IRemoteSource and RemoteSource, parseSummary to AmSatRepository, and summaryCount to SatStatus. All eight test-file implementations of IRemoteSource were updated for the new method.
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.
