On page 15 it says: "3: Defined as current drawn during continuous
operation at a 10Hz update rate." Could this be a hint, that the module
can actually operate at a max. update rate of 10Hz?

Is there any GTA04 board, which already has a W2SG0084i installed? If
so, we could try to query/set the output rate according to chap. 5 "NMEA
Input Messages", using the message ID 103. Also chap. 6.2 "OSP Input
Messages" look interesting, especially message 0x81.
