NEC’s GNSS Analyzer — capable QZSS-focused GNSS logger but limited to external receivers
GNSS Analyzer records and visualizes NMEA positioning logs (satellite radar, signal C/N and map), imports logs and receives QZSS DC Reports, but is a niche utility that requires a QZSS‑supported external BLE receiver (leased via QZSS) so it’s not useful as a standalone phone/tablet GNSS app.
GNSS Analyzer is a specialized application designed to facilitate the recording of positioning data using receivers compatible with the Quasi-Zenith Satellite System (QZSS). The software provides comprehensive tools for monitoring satellite signals, visualizing current location, and managing logged data.
Key features of GNSS Analyzer include:
- NMEA Data Monitoring: It displays real-time NMEA logs generated by connected receivers via Bluetooth Low Energy (BLE). Users can also record these logs directly on their device and share them via email for subsequent analysis.
- Satellite Radar and Signal Analysis: The application offers satellite radar visualization and displays signal strength (C/N ratio), enabling users to assess satellite visibility and performance.
- Current Position Display: Users can view their real-time location on an integrated map, providing spatial context for the recorded data.
- Log Import and Playback: Recorded NMEA logs can be imported into the app, allowing users to review satellite data, signal levels, and positional information at selected timestamps.
- Disaster and Crisis Management Communication: The app displays messages from QZSS’s Disaster and Crisis Report (DC Report) service. Users can select language preferences (English or Japanese) and filter messages based on geographic location.
Note: A QZSS-supported receiver is required to utilize these functionalities. Such receivers are available free of charge through the official website: https://qzss.go.jp/appli-demo/appli01_info.html.
This application is compatible with iOS versions 13 through 18, ensuring broad device support for users operating on various iOS platforms.
