GPS jamming and spoofing

[Dr.Gadget]

Recently saw the video about GPS jamming/spoofing Resilience Monitoring With State-of-the-Art Multi-Band GNSS Receivers - Kwinten Depestel, Septentrio and saw that there are two new options for EKF2_GPS_CHECK (Spoofing and Jamming).

I cannot find documentation, guides or similar on this topic.
What is the current state of detecting GPS jamming/spoofing in PX4? Are there any actions that can be made when this is detected? Show user, change flight mode etc. Looking for all infromation I can get.

I am using a Septentrio Mosiac Go-H if it helps.

E.g how can I get the symbol shown in the presentation?

GNSS_INTEGRITY is a recent message so I suspect it is on main only, and this is likely a QGC daily built. I’d try out that combination. The PR it was added in was Septentrio resillience reporting by Louis-max-H · Pull Request #25012 · PX4/PX4-Autopilot · GitHub. This looks like Septentrio so you’d need to get their hardware for whatever driver sets SensorGps (UORB message) | PX4 Guide (main).

IN other words, no, there is no documentation of this - the message is emitted if the driver sets SensorGps (UORB message) | PX4 Guide (main)

PS As to what you can “do about it” if Jamming is detected, that will be covered in docs in [Docs] GNSS-Denied Configuration by hamishwillee · Pull Request #25955 · PX4/PX4-Autopilot · GitHub
