GnssLogger by Google enables in-depth analysis and logging of all types of location and sensor data such as GPS (Global Positioning System) network location and other sensor data. It comes with the following features:

HOME TAB:
● Control various data logging such as raw GNSS measurements GnssStatus NMEA navigation messages sensor data and RINEX logs.

LOG TAB:
● View all location and raw measurement data.
● Control offline logging using 'Start Log' 'Stop & Send' and 'Timed Log'.
● Enable specific items to be logged using corresponding switches in Home Tab.
● Delete existing log files from disk.

MAP TAB:
● Visualize on GoogleMap the location provided by GPS chipset Network Location Provider (NLP) Fused Location Provider (FLP) and computed Weighted Least Square (WLS) position.
● Toggle between different map views and location types.

PLOTS TAB:
● Visualize CN0 (Signal Strength) PR (pseudorange) Residual and PRR (pseudorange rate) Residual vs time.

STATUS TAB:
● View detailed information of all visible GNSS (Global Navigation Satellite System) satellites such as GPS Beidou (BDS) QZSS GAL (Galileo) GLO (GLONASS) and IRNSS.

SKYPLOT TAB:
● Visualize the data of all visible GNSS satellites using a skyplot.
● View the average CN0 of all the satellites in view and the ones used in fix.

AGNSS TAB:
● Experiment with Assisted-GNSS functionalities.

WLS Analysis TAB:
● View the Weighted Least Square position velocity and their uncertainties computed based on raw GNSS measurements.
● Compare the WLS results to the GNSS chipset reported values.
