RAK 2245 GPS Pins

Hey,
I am working with a RAK2245 and I need to exploit his GPS module. In the pinout section of RAK2245 specification I see Standby and reset gps pins. I don’t found any guide about the use of this pins. Is it possible to have more information about standby pin ? I would like to know if I can use power saving mode of gps and how do it.

Thanks
Ben
