GnssLogger App v3.1.0.7

GnssLogger by Google presents a comprehensive solution for analyzing and logging various types of location and sensor data, including GPS data, network location, and additional sensor inputs. It is accessible on both smartphones and smartwatches, catering to different user needs.

Features for Phones:

• HOME TAB: Users can manage data logging options including raw GNSS measurements, GnssStatus, NMEA data, navigation messages, sensor data, and RINEX logs.
• LOG TAB:
  • Access location and raw measurement data.
  • Control offline logging with functionalities such as 'Start Log', 'Stop & Send', and 'Timed Log'.
  • Select specific items to be logged via the corresponding switches in the Home Tab.
  • Remove existing log files from storage.
• MAP TAB:
  • Visualize locations on Google Maps from GPS chipsets, Network Location Provider (NLP), Fused Location Provider (FLP), and computed Weighted Least Square (WLS) positions.
  • Switch between varied map views and types of location data.
• PLOTS TAB: Display CN0 (Signal Strength), PR (pseudorange) Residuals, and PRR (pseudorange rate) Residuals over time.
• STATUS TAB: Review detailed information regarding all visible GNSS satellites including GPS, Beidou (BDS), QZSS, GAL (Galileo), GLO (GLONASS), and IRNSS.
• SKYPLOT TAB:
  • Visual representation of all visible GNSS satellites through a skyplot.
  • Track average CN0 values for all satellites in view as well as those utilized in position fixing.
• AGNSS TAB: Experimentation with Assisted-GNSS functionalities is available.
• WLS Analysis TAB:
  • Examine Weighted Least Square positions and velocities along with their uncertainties based on raw GNSS measurements.
  • Compare WLS outcomes to the values reported by the GNSS chipset.

Features for Wear OS 3.0 and Higher Watches:

• Monitor real-time status information from the GNSS chipset.
• Log various GNSS and sensor data in CSV and RINEX formats.
