Cannot find GPS1_MB parameters

ArduRover

I am using ArduRover 4.5.2. I am trying to set up gps for yaw using dual antenna CUAV C-RTK2HP. I need to set the location of the antenna but I can not find parameters

GPS_MB1_OFS_X, GPS_MB1_OFS_Y, GPS_MB1_OFS

Have these parameters been removed in this version. If so how I set the location effectively. If not, how can I find them. Thanks

To find the necessary parameters, follow these steps:

  1. Set `GPS_MB1_TYPE = 1 in the parameter list.
  2. Refresh the parameters after making this change.
  3. Go to the Full Parameter List and scroll down to GPS_MB1.
  4. You should see a plus (+) symbol to the left of GPS_MB1. Click it to expand and reveal the required parameters.

This should display the parameters you need, including:
• GPS_MB1_OFS_X
• GPS_MB1_OFS_Y
• GPS_MB1_OFS_Z

If the parameters do not appear after refreshing, double-check that GPS_MB1_TYPE is correctly set, and try refreshing again.

I am having this issue with a speedybee f405 v4. Firmware V4.6.3.
No matter what I set GPS1_TYPE to (I want 25 for unicore moving baseline) I cannot get the MB_OFS values to appear.
Any ideas?

The feature is unavailable for F4 autopilots (as can be seen here https://firmware.ardupilot.org/Rover/stable/speedybeef4v4/features.txt).

You may be able to use the custom firmware server to enable the feature, but I can’t promise it will work (or work well).

ah bummer thanks. I may try it anyway and see what happens.

I made a custom firmware with GPS_MOVING_BASELINE enabled and it works. Not sure why this isn’t available in the stock firmware as now I will always have to have a custom build.
In any event, thanks for the heads up. This speedybee doesn’t have a compass and I wanted to use one of these cheap UM982 dual RTK units which, much to my surprise, works perfectly well.

I do get “bad compass health” messages but the heading is working perfectly despite all COMPASS_USE are set to 0.
