u-blox c027 - rtk gps base station

Can u-blox c027 act as rtk gps base station?

Question relating to:

The u-blox-C027 is a complete starter kit that allows quick prototyping of a variety of applications for the Internet of Things. The application board has a MAX-M8Q GPS/GNSS receiver and ...

MAX-7Q does not support RXM-RAW and RXM-SFRB UBX messages, but the same raw data can be recovered by parsing the undocumented TRK-SRFB(X) and TRK-TRKD5 messages. So the right answer is: c027 can be used for RTK, you only need to bump up the UART speed and write your own UBX-TRK parser. Porting parts of the RTKLIB source code will allow to stream the RTCM3 (or RTCM2 if you really need it) messages over ethernet or wireless modem.

No.

To act as an RTK base station you require access to the raw measurements (pesudorage, carrier phase, doppler etc...).

As shown in the document linked below the Max-7Q device on the c027 doesn't support raw data output.
