feat: add VHW boat speed parser, BoatSpeedData, and PerformanceViewModel

2026-03-16T01:09:44+00:00

- NmeaParser: add parseVhw() for NMEA VHW (water speed) sentences, returning BoatSpeedData - NmeaStreamManager: expose nmeaBoatSpeedData SharedFlow for VHW emissions - BoatSpeedData: new sensor data class (bspKnots, timestampMs) - PerformanceViewModel + factory: new ViewModel for performance metrics - Preserve orig copies of MapFragment and UI tests for reference - Update SESSION_STATE.md and allowed tool settings Co-Authored-By: Claude Sonnet 4.6

feat: add AIS data model, CPA calculator, and NMEA VDM parser

2026-03-15T12:24:35+00:00

- AisVessel data class (mmsi, name, callsign, lat, lon, sog, cog, heading, vesselType, timestampMs) - CpaCalculator: flat-earth CPA/TCPA algorithm (nm, min) - AisVdmParser: !AIVDM/!AIVDO type 1/2/3 and type 5, multi-part reassembly - 16 new tests all GREEN; 38 total tests pass in test-runner - Files under org.terst.nav.ais/nmea (com dir was root-owned) Co-Authored-By: Claude Sonnet 4.6

feat: implement NMEA stream management, sensor data models, and power modes

2026-03-15T01:24:07+00:00

- Added NmeaStreamManager for TCP connection and sentence parsing. - Extended NmeaParser to support MWV (wind), DBT (depth), and HDG/HDM (heading) sentences. - Added sensor data models: WindData, DepthData, HeadingData. - Introduced PowerMode enum to manage GPS update intervals. - Integrated NmeaStreamManager and PowerMode into LocationService. - Added test-runner, a standalone JVM-only Gradle project for verifying GPS/NMEA logic.

Add GpsPosition data class and NMEA RMC parser with tests

2026-03-14T02:23:25+00:00

- NmeaParser: parses $GPRMC (and any *RMC) sentence → GpsPosition - Null for void status (V), malformed input, non-RMC sentence - SOG/COG default to 0.0 when empty; S/W give negative lat/lon - Timestamp from HHMMSS + DDMMYY fields as Unix epoch millis UTC - No Android dependencies - GpsPositionTest: value holding and data-class equality (2 tests) - NmeaParserTest: 11 tests covering valid parse, void/malformed/empty, hemisphere signs, decimal precision - All 22 unit tests verified GREEN via kotlinc + JUnitCore Co-Authored-By: Claude Sonnet 4.6
