gga viewer

Parses a single NMEA GGA sentence to yield a structured snapshot of GPS fix data. It converts latitude and longitude from degrees-minutes-seconds format to decimal degrees, extracts time, fix quality, satellite count, HDOP, altitude, and geoid height, and surfaces them in a machine-readable format. The tool validates the checksum when present and returns null for missing fields. Conceptually, it tokenizes the sentence, maps tokens to predefined positions, and normalizes numeric fields for immediate use in pipelines. This benefits developers integrating GPS data into applications, field technicians validating device readings, and data analysts performing quick geospatial checks without manual parsing. Unique value lies in strict adherence to GGA structure, robust handling of incomplete sentences, and straightforward export options to JSON or CSV for automated workflows. Core features include real-time parsing of a GGA line, unit-consistent outputs, and clear signaling of any data integrity issues. Typical use cases include logging GPS fixes, feeding dashboards, and validating device performance against expected satellite counts and HDOP thresholds.
