Question Location Service

In the documentation of the LocationService you can find the following text " Higher values like 500 don't require the device to use its GPS chip and thus save battery power. Lower values like 5-10 provide the best accuracy but require the GPS chip and thus use more battery power. " -> https://docs.unity3d.com/2023.1/Documentation/ScriptReference/LocationService.Start.html


But why is it called a GPS chip? Because if I understand the theory correctly behind GNSS systems. A lot of the cellphones nowdays are using a multi-GNSS chip to talk with different GNSS systems. And the phone then uses the different GNSS systems to calculate a more accurate location. So its not a GPS chip but a GNSS chip and this chip can talk with for example the GPS system but also with the Glonass system. Or is my theory wrong?
