Passwords for the release keystore were committed in plaintext to a
public repo. Move them to gitignored local.properties with an
environment-variable fallback. Keystore file itself stays in $HOME.
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.
- onStationAGrid/onStationBGrid store the trimmed upper-cased grid instead
of the raw input (ol63 used to stay lowercase in the UI)
- drop the local latLonToGrid/gridToLatLon copies and reuse the domain
QthConverter, removing the drift risk between two implementations
- inject computeDispatcher (default Dispatchers.Default, no behaviour
change) so the pass computation is unit-testable on a test scheduler
- add MutualViewModelTest (15 cases): init prefill, grid/lat-lon linkage,
error paths, main-list reuse, fallback search, sorting, clearError
- 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.
Replace the radar page calendar action with the map icon and route the action through the Passes map flow so the Passes navigation item remains selected.
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.
Store the offset (kHz) per NORAD catalog id in SharedPreferences so
each satellite's last entered offset is restored when reopening the
frequency calculator.
- 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
Match page UI:
- Always show a meaningful status line in the top bar instead of leaving the second row blank on first entry.
- Add a compact status chip for waiting, calculating, result, no-match, and error states.
- Remove the duplicate intro card so the first screen starts directly with station inputs.
Pass list sun times:
- Compute sunrise/sunset from each visible date group's 00:00 in the selected timezone.
- Avoid using an arbitrary pass AOS as the rise/set search start, which could jump later-day headers to the following day's events.
- Radar pager now defaults to Transceivers tab (initialPage=0)
- Transceivers don't auto-expand (selectedUuid defaults to null)
- Mutual page default minElev changed from settings value to 0.0
- Display filters out portions below the minElev threshold
Elevation curve chart and mutual radar plot now only show the portion
where both stations are above their respective minimum elevation.
The curves are filtered at display time, the pass search still uses
the 0° horizon boundary for consistency with the Passes page.
Removed the automatic posA=stationPos override. Added a button
'当前精确位置' below the grid input that fills in the exact station
position from settings (lat/lon + grid). Users can now freely edit
the position fields and use the button when they want the exact
position.
Root cause: gridToLatLon used (lon+180)%360-180 and (lat+90)%180-90
for normalization, treating grid values as from prime meridian/equator
when they are actually from IDL/South Pole. A 6-char grid like OL62AA
(112°E, 22°N) was returning -67.96°, -67.98° (Atlantic Ocean).
Also added bidirectional sync: entering a grid auto-fills lat/lon,
entering lat/lon auto-fills the 6-char grid, so users can verify.
getFullPosition and getElevation both call calculateObs internally,
but the elevation values reported by the user (-60°) suggest they may
differ. Now elevation is computed via getElevation (same as getLeoPass),
while getFullPosition is only used for azimuth.
The passes list AOS/LOS times can be stale or computed for a different
station position, causing elevation curves to show -60° at pass start.
The independent search (refineEdge + sampleMutualPass) always computes
elevation for the actual positions. With posA now set to the exact
station position, the pass times should match the main page.
The refineEdge function re-computed boundaries using the grid-center
position (posA), which differs from the exact station position that
the passes list was computed with. This caused all passes to be
filtered out. Now we trust the pass list's AOS/LOS times directly
and just sample the elevation/azimuth curves.
If the main pass list (satelliteRepo.passes) is empty or the common
window check filters everything out, fall back to the independent
search algorithm so the user always gets results.
findMutualPasses was computing passes independently with its own
search algorithm, which produced different results from the main
page's getLeoPass. Now it directly reuses satelliteRepo.passes,
which is the same list shown on the main passes page. The only
additional computation is refining the common window for station B
and sampling elevation/azimuth curves.
Root cause: mutual search used the min-elevation threshold (default 10°)
as the AOS/LOS boundary, while the main radar uses the 0° horizon
(getLeoPass). With identical stations the windows therefore never
matched. Also, an in-progress pass was counted as a new one.
- AOS/LOS boundaries now at the 0° horizon (refined to 1s)
- Skip in-progress mutual windows at search start (like getLeoPass)
- Filter requires BOTH stations to reach their min elevation
- Default min elevation follows the main radar passes setting
- Elevation ring labels were inverted (90/60/30 from outer to inner);
now 30/60/90 correctly from outer ring to center
- Split track paths at the 0/360° azimuth wrap in both MutualRadarView
and main RadarView, so passes crossing due north no longer draw a
line straight across the plot
Track line is no longer time-limited (always shows the whole mutual
arc). The station-B live position is drawn separately on the line
using the same pulsing-dot mode as the local station.
- ElevationCurveChart is now controlled (progress + onProgressChange)
- MutualRadarView shows shared time-cursor positions for both stations
and is draggable/tappable to move the cursor
- MutualPassCard owns a single dragProgress feeding both charts, so
dragging either chart moves the other in sync
- 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
Absolute epoch millis (~1.7e12) exceeds Float precision (ULP ~131s
at that magnitude), so 5s-spaced samples collapsed onto identical
x coordinates, producing a stepped/jagged curve. Use Long relative
time deltas (sample - start) before converting to Float.
- 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
- Reduce sample interval from 10s to 5s for smoother curves
- Add refineEdge() to find exact AOS/LOS at 1s resolution
- Curve now starts/ends at the correct horizon-crossing points
- Pre-fill station A grid from settingsRepo.stationPosition
- Find ALL mutual passes per satellite (not just first)
- Fix Color.hashCode() -> Color.toArgb() for native canvas paint
- Use 2min gap between pass searches to avoid duplicates
Bug: OrbitalObject.getElevation() returns radians, but
MutualViewModel was comparing it directly with degree values
from the slider (10-90), causing no matches to be found.
Fix: add elevationDeg() helper that converts to degrees.
Also add Maidenhead grid square input support (4/6/8 chars)
alongside existing lat/lon fields. Grid takes priority when
filled.
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
Extract dateFormat() helper to ensure computeSunTimes and
groupPasses use identical date format, fixing sunrise/sunset
display bug.
For Chinese locale: "2026年8月1日 星期六"
For English locale: "Sat, 01 Aug 2026"
DateFormat.FULL may cause inconsistent date labels between
computeSunTimes and groupPasses, leading to missing or
wrong sunrise/sunset times. Revert to the original pattern
"EEE, dd MMM yyyy" but with Locale.getDefault() so day
names follow the system language.
Keep number removed from pass list (Components.kt) and
pass detail (PassesScreen.kt) as requested, but restore
it in the satellite selection list (SatellitesScreen.kt).
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.
Replace SimpleDateFormat("EEE, dd MMM yyyy") with
DateFormat.getDateInstance(DateFormat.FULL, locale) which
automatically uses the correct format for each locale:
- Chinese: "2026年8月1日 星期六"
- English: "Saturday, August 1, 2026"
- Other locales: their respective conventions
PassesViewModel and PassesScreen used Locale.ENGLISH for
SimpleDateFormat, causing day-of-week names like 'Sun' to
always show in English. Changed to Locale.getDefault() so
the device's language setting is respected.
Affects: 'EEE, dd MMM yyyy' date labels in the pass list
(group headers and sun times), and 'HH:mm:ss' time format.
- 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
