Issue changing frequency about ublox HOT 11 CLOSED

How to solve the problem? I have a similar problem on ROS.

from ublox.

I am sorry there is no real fix in the ros package I could get to work. It seems like the configuration via this package does not work for the ublox module. The way I did it is changing it in u-center and saving the configuration to the device.

Thank you for your prompt response.
Could I consult you about how to save the configuration to the device in u-center?

from ublox.

Yes I can do that. I think ublox forum is a good place to start. However if you have issues just let me know.

Thank you for your reply.

The coordinate is WGS-84(Latitude、Longitude、Altitude) above.
But I have the problem to consult you.
In order to fuse the location data, I want to transfer the WGS-84 into ECEF or Body frame.
What could I do?

Best regards

Are you using the F9P with a reference basestation station for rtk corrected gps?

from ublox.

I can transfer the WGS-84 into ECEF frame successfully now.
Do you have any method or idea to transfer the ECEF to ENU(east, north, up)??

My object is to achieve the autonomous navigation.
(ps: I used the ZED-F9P with a reference base station station for rtk corrected gps)
Thank you for your help.

If you use the F9P with a basestation you should configure the GPS in u-center to publish RELPOSNED. This is the rover position relative to base. You could take your initial reading as an offset to get the origin of the rover. After that it is a just a matter of moving NED to ENU, which does not need a complicated conversion. The message you should see in this package is here.

OK, thank you for your suggestion. $roslaunch ublox_gps ublox_device.launch


in node.h

My topic /ublox_gps/NED_position has no information.
Could you give me some advice?

Thank you!

Ok so looking at your code it seems like you are just creating an empty message and publishing it. That is not what I meant.
The way to go is:

1. enable NAV-RELPOSNED in u-center and safe configuration to ZED F9P
2. change your cfg in ros for the ublox by adding

publish:
  nav:
    relposned: true

3. launch and check if the ublox package is publishing a relposned message

Maybe also check out this package https://github.com/ros-agriculture/ublox_f9p
this might already do what you need

I can read iTow info in /ublox_gps/navrelposned(topic), but relPosN、 relPosE、 relPosD doesn't show the value. Could you tell me what should I do?

Thank you!
