In RTK you have base and rover receivers.

Then you also want to enable periodic RXM-RAW and RXM-SFRB reports. These should be in CFG-MSG. Look for "Rate" and set it to something non-zero. (I am just guessing here since I really have never even seen u-center). > Is this right? The RTKlib shows nothing. Is the GPS receiver sending anything over the serial port? If not, you can't blame rtklib :-) _______________________________________________ This message is sent to you from [email protected] mailing list.
