    You can change the GPS baud rate, yes. It will be available under the com settings configuration heading in the Serial Interface, if you connect to it with your PC. More details about the actual register settings can be found in the datasheet.

    Other than connecting the GPS module and making sure the baud rate is correct, you won’t have to do anything special to tell the UM7 to take care of incoming GPS packets.

    Hi Ranu,

    The UM7 doesn’t support 2D calibration at this time. If you absolutely need it, then I’d recommend that you use the magnetometer output and use it to compute heading directly. Any calibration will have to be performed on your end.

    Hi Jose,

    The Reset to Factory command affects all configuration registers that have been changed by you.

    Hi John,

    Thanks for the detailed information. Everything on your UM7 appears to be set up correctly. Do you have a way of sending us the NMEA GSV packet sent by your GPS module?

    Yeah, that should do it. Be aware that in quaternion mode, the magnetometer can influence all angles – yaw, pitch, and roll, not just yaw.

    Is quaternion mode enabled? Quaternion mode must be turned on for the attitude quaternion to be updated. You can do that from the Configuration tab in the Serial Interface.

    Hi sven,

    To estimate yaw (or the yaw component of the quaternion), the magnetometer on the UM7 must be calibrated. You can use the Serial Interface to collect data, compute the calibration, and write the settings to the device. It can also help to issue a “zero rate gyros” command.
