RTK Base station with MAVLink

[Andrew Welch]

Hi all,

Does anyone have any idea on setting up RTK base station with MAVLink?

It am currently able to receive RTCM messages from the base station. However, when I tried to send lat/lon coordinates, altitude, and accuracy, it seems that the accuracy does not increase.

I have tried using other GCS to survey, and there are no issues with them.

May I check if anyone has any idea on how to do this? Or does anyone has any reading information I can read up on?

Thank you for your help in advance.

No idea sorry. All I know is that the base station GCS sends RTCM message to the ground station, which re-assembles any partial messages and then writes them to the GNSS once a complete message has been received. Whatever you do will have to mimic that.

You might want to try asking  on the flight stack-specific forums.

First if you are using your own code then you would need to pack the rtcm message into the GPS_RTCM_DATA mavlink message and then send it
