Add a full-screen update checker accessible from a button at the
bottom of the settings page. It queries the fork's GitHub latest
release and can download + install the APK in place.
- UpdateRepository (core/data): fetch releases/latest via GitHub API,
parse tag/description/APK asset, stream APK download to cacheDir
- VersionComparator (core/domain): compare 4.4.6-ba7opf.N style tags
(base version first, then build number; v-prefix tolerant) + tests
- IMainContainer/MainContainer: inject updateRepo
- UpdateCheckerScreen (feature/settings): shows current version,
checks for updates, displays latest version + release notes, and a
Download & install button; FileProvider hands the APK to the
system installer
- SettingsScreen: bottom entry button, full-screen page toggle
- AndroidManifest: REQUEST_INSTALL_PACKAGES permission + FileProvider
- i18n strings (en/zh)
Port the upstream drag-reorder pattern (dragHandle/draggedVisual/
autoScroll/DragRowState) so custom data source rows can be reordered
by long-pressing the handle icon, replacing the old move-up button.
- Add 40dp drag-handle box at row start with long-press gesture
- Live reorder while dragging (neighbour squeeze + spring settle)
- Edge auto-scroll during drag
- Keep per-source enabled checkbox + HTTP status label
This file also carries the #242 data-source dialog UI (enabled
checkbox, status code label, restore-default button) which shares
the same sourceSection function and cannot be cleanly split.
- Point the built-in SatNOGS source at db.satnogs.org/api/tle/?format=3le
(the CelesTrak satnogs group is a separate, slower subset); rename the
old CelesTrak source to 'CelesTrak SatNOGS'.
- Add a one-time migration in SettingsRepo: installed apps that already
persisted a satelliteUrls list containing the old CelesTrak SatNOGS URL
get the real SatNOGS TLE URL inserted right after it.
- Dedupe imported satellites by catnum and radios by uuid in
DatabaseRepo.updateFromRemote so multiple sources don't insert the
same primary key twice.
- Test: importing JAMX-0825b (NORAD 98248) from the real SatNOGS source.
Start AMSAT status prefetch when the app enters foreground and share the in-flight request with the status page fetch path to avoid duplicate network requests.
When adjusting RX in passband mode (via +/- buttons or slider), the old
code used TransponderMapper.mapDownlinkToUplink (pure passband mapping
without Doppler compensation), producing ~10kHz error at LEO velocities.
Fix: use DopplerFrequencyCalculator.computeUplinkFromDownlinkWithOffset
for the full TX-from-RX round-trip, matching the RX→PASSBAND button
onClick logic. Also fixed frame mismatch: position now uses txLow/txRange
(Doppler-shifted frame) consistently.
- Adjust ic_satellite_alt translateY from -226.13 to -230.5 so icon
is centered vertically (not clipped at bottom)
- Replace ic_match with ic_radio_tower (MDI) for Mutual page
Port upstream PR #234 to fork main:
- New feature:status module (SatStatusScreen, SatStatusViewModel)
- New AmSatRepository + IAmSatRepository + SatStatus models
- RemoteSource: AMSAT API methods (getAmSatCatalog, getAmSatReports)
- MainContainer/IMainContainer: DI injection
- MainTheme: AMSAT status colors (tertiary slots)
- Chinese translations added for all AMSAT strings
- 26 unit tests passing
Note: navigation entry not included — upstream PR #234 intentionally
left it out pending UI restructuring. Add AMSAT to your nav bar or
menu as desired.
Use combine(selectedIds, stationPosition) in SatelliteRepo.initRepository
so that passes are recalculated on either satellite selection change or
station position change. StateFlow already emits distinct values.
- isNamedLinearTransponder: match ' Lin' prefix (AO-7 style) and
add fallback branch (hasLinearName && hasLinearMode) for entries
with 'Linear'/'Lin' but no 'transponder' word (AO-7, AO-73)
- add deduplicateTransponders: merge entries sharing the same
uplink/downlink frequency range, preferring non-CW entry
(AO-7 Mode A had separate SSB and CW entries; JO-97 had
separate CW and SSB Transponder entries)
- apply dedup in CalculatorPage filter chain
- 6 new tests, 23 total, all passing
- MutualViewModel is Activity-scoped, so returning from Radar keeps query results
- TrackSampleData gains time field for live cut-off
- Removed standalone mutual card from radar page
- RadarViewCompose draws optional dashed station-B track + current dot
- RadarScreen builds trackB from mutual data up to current time
- MutualPass now carries TrackSample (azimuth/elevation for both stations)
- New MutualRadarView: polar plot with elevation rings (30/60/90),
cardinal spokes, solid A-track vs dashed B-track, AOS/LOS markers
- Shown in expanded mutual pass card and radar page mutual card
- Fix cubic Bezier control points (proper Catmull-Rom to Bezier conversion)
- Refine AOS/LOS more robustly by walking from edge into the pass window
- Still 5s sampling for smooth curves
Port satlover.de dual-station pass matching feature:
- New feature/mutual module with mutual pass data model
- MutualViewModel: compute overlapping passes for two stations
- ElevationCurveChart: Canvas-based dual elevation curve with drag
- MutualScreen: input form + results with expandable cards
- Navigation: add Mutual tab to bottom navigation bar
- i18n: add Chinese/English strings for new feature
Use MaterialTheme.colorScheme.primary for satellite name
text in all three lists (Components, SatellitesScreen,
PassesScreen), matching the color that was previously
used for the catalog number.
Remove the NORAD catalog number (e.g. '44444 - ') prefix
from satellite names in three places:
- Pass list items (Components.kt)
- Satellite selection list (SatellitesScreen.kt)
- Pass detail view (PassesScreen.kt)
The number is still accessible via satellite details if needed.
- Add newColumnCount tracking to CwSpectrogram
- CwDecoder now processes each new column individually for timing
- Each column = 8ms at 8000 Hz sample rate
- Proper per-column iteration through spectrogram history
Complete rewrite inspired by Morse Expert / CW Skimmer (VE3NEA):
- CwFFT: radix-2 FFT (256-point) for time-frequency analysis
- CwSpectrogram: sliding-window waterfall (40 cols x 33 bins, 8ms resolution)
- CwBayesianDecoder: Gaussian probability replaces hard dit/dash thresholds
- CwChannelTracker: multi-channel peak detection (up to 3 signals)
- CwDecoder: integrates all components, monitors 200-1200 Hz simultaneously
Key advantages over v2 (ggmorse):
- Frequency-agnostic: full spectrum monitored, not locked to one tone
- Multi-channel: tracks multiple signals in parallel
- Bayesian: probability-based decisions, not hard ratios
- Doppler tolerant: frequency drift just moves energy between bins
- After initial pitch lock, re-scan every ~8 seconds in a narrow
±100 Hz window around the current pitch estimate
- Only re-lock if pitch change > 20 Hz (avoids jitter)
- Helps maintain lock when Doppler tracking has residual error
- Add CwDsp with FIR bandpass filter, envelope detection, Goertzel tone detector
- Add CwDecoder with real-time Morse timing analysis and character lookup
- Add CW state/actions to RadarState, wire into RadarViewModel
- Add collapsible CW decoder panel to transceivers page
- 19 unit tests covering DSP, Morse table, and decoder state
- Shares IAudioCapture with SSTV, auto-stops SSTV when CW starts
- Add DopplerFrequencyCalculator utility with passband mapping + Doppler correction
- Add MHz input UI with real-time 1Hz refresh during pass
- Add kHz offset for downlink frequency correction
- TX/RX fields on same row for compact layout
- 40 unit tests covering linear/FM/inverted transponders
