GNSS Analyzer is a utility tool designed to record and visualize NMEA positioning data from external QZSS-supported receivers via BLE. It provides real-time satellite radar, signal level (C/N) monitoring, and map-based location tracking. The app also supports the reception of DC Report messages for disaster and crisis management. ## Key Features - **NMEA Logging**: Records and exports NMEA positioning data from connected BLE receivers for external sharing. - **Satellite Monitoring**: Displays real-time satellite radar and signal-to-noise ratio (C/N) levels. - **MapSky Visualization**: Maps current positioning data and allows for the import and display of previously recorded NMEA logs. - **DC Report Integration**: Receives Satellite Report for Disaster and Crisis Management messages provided by QZSS services. ## Who is it for? Professional users and developers requiring precise positioning data analysis using external QZSS-supported hardware. ## Links - [App Store](https://apps.apple.com/us/app/gnss-analyzer/id1040750117?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/gnss-analyzer) --- *This is an overview report.
