Source: [https://docs.qualcomm.com/doc/80-42221-1/topic/introduction-to-tps-skylogger-app.html](https://docs.qualcomm.com/doc/80-42221-1/topic/introduction-to-tps-skylogger-app.html)

The Qualcomm® Terrestrial Positioning Service (TPS) SkyLogger
    application is designed to allow users to map an indoor location and help to improve the quality
    and accuracy of location returned by the TPS API.

The SkyLogger application collects and logs the field test data to replay and analyze the
      performance and accuracy of the Qualcomm hybrid positioning system. To achieve this, the
      application leverages the TPS location SDK for Android.

This video helps you to understand how to install SkyLogger application and run field
      tests.
