EKF2 replay doesnt reproduce in-flight results with default parameters

PX4 Autopilot Flight Controllers 💻
1

I am trying to use the ekf2 replay as in: Redirecting to latest version of documentation
PX4 verison: v1.8.2

My orb_publisher.rules:
restrict_topics: sensor_combined, vehicle_gps_position, vehicle_land_detected
module: replay
ignore_others: false

replay_params.txt: untouched with flight log.

Log file type: ulog.

command run: make posix none

The replay estimate and real flight values don’t match. On plotting estimator ->state 1 for instance:

inflight_state1
inflight_state11025×422 31.7 KB

replayed_state1
replayed_state11025×422 34.4 KB

Also in replay alone i had a huge timeslip after approx 8-10s of logging.

timeslip
timeslip798×328 17.5 KB

Already answered in https://github.com/PX4/Firmware/issues/12504.

Please don’t double post like this. It means double work for me.

There was no answer for it in the link you provided, it just says that this issue been there since long time, but didn’t say why or how to solve it?

5 years later. Wow, what a necropost!

I suggest to open a new thread, give some context what you’re trying to do, explain your issue, what you tried, what happened, your questions, etc.

Otherwise, I’m not sure how I could help with that.
