Based on https://forum.rakwireless.com/t/gps-accuracy-on-rak12500/12660/13

BeeGee's code is using setMeasurementRate(). I've also seen this elsewhere and i'm wondering what this exactly does. Especially in combination with the powersave mode.

https://content.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_UBX-13003221.pdf has documentation on the setting UBX-CFG-RATE and it mentions that the setMeasurementRate() is influenced by the power save mode. So setMeasurementRate() is primarily interesting when we're in continuous mode.

Todo here is to read the default value from the device and see if we're happy with that or not.
