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.
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.
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.
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.
