## What is Sentencewake?

Sentencewake turns raw NMEA 0183 logs into an inspectable offline voyage record while keeping every conclusion traceable to its source line.

SEE THE VOYAGE
• Import text, log, and NMEA files from Files.
• Fuse RMC, GGA, and GLL position reports into a timed route.
• Review distance, duration, speed, checksum health, and instrument inventory.
• Inspect native route, speed, and quality charts.

AUDIT EVERY SENTENCE
• Distinguish valid, invalid, and missing transmitted checksums.
• Search and filter by issues, position, or sensor records.
• Inspect talker, formatter, fields, line number, and raw source together.
• Export only checksum-valid lines when a cleaned log is needed.

FIND WEAK SEGMENTS
• Detect fix gaps, coordinate jumps, duplicate sentences, void fixes, high HDOP, low satellite counts, and heading disagreement.
• Compare depth, wind, temperature, speed, and heading channels.
• Jump from a quality finding back to the exact source sentence.

WORK WITHOUT A SERVER
• Use a complete sample log immediately or import your own.
• Consult a dedicated offline reference for 14 common NMEA formatter families.
• Save the current analysis locally and export a native PDF report.

No account, advertising, subscription, server, or network connection is required.

Sentencewake is a diagnostic aid, not a navigation instrument. A valid checksum does not establish sensor accuracy, safe navigation, datum correctness, timing integrity, or equipment suitability.
