I have questions regarding the use of Replay to run EKF with external data.
I had good progress since my last topic Using the Replay tool to run EKF with external IMU and GNSS data files
Based on AP_logger_test and CSV reading I managed to save IMU and GNSS data in a dataflash log :
Now that I have a log file with IMU data and GNSS raw + pvt data, I’m running it through Replay.
The soft does not complain (i.e. it is going up to the end of processing) but I don’t get relevant results from the NKF nor do I get any data from EKF :
What can I do to improve my results here and get and output for EKF ?
Is there documentation about the meaning of the logged NKF values ? I understood that NKF4.SV is the ground speed but how do I know the others ?
