Information
Google Chrome supports to track the users' physical location using GPS, data about nearby Wi-Fi access points or cellular signal sites/towers (even if you're not using them), and your computer's IP.
Rationale:
From a privacy point of view it is not desirable to submit indicators regarding the location of the device, since the processing of this information cannot be determined. Furthermore, this may leak information about the network infrastructure around the device.
Solution
To establish the recommended configuration via Group Policy, set the following UI path to Enabled with Do not allow any site to track the users' physical location selected from the drop down:
Computer Configuration\Administrative Templates\Google\Google Chrome\Content Settings\Default geolocation setting
Impact:
If this setting is disabled, chrome will no longer send data about nearby Wi-Fi access points or cellular signal sites/towers (even if you're not using them), and your computer's IP address to google.
Default Value:
Enabled. Ask whenever a site wants to track the users' physical location
