Hi everyone, can we pls review during the dev call following PRs from Septentrio?

Resilience PRs

→ PX4-Autopilot: #25012

→ QGC: #13009

Base station PR

→ QGC: #12686

Extra questions:

Base Station QGC PR (#12686): The PX4 side for this is already merged and will be in next release (PX4_Drivers #178). Can we include the QGC PR in the next release to complete the feature? This would also help teams like ARK Electronics who are testing it manually right now.

Resilience PRs (#25012, #13009): Can these also be included in the next releases? The feature is isolated to the Septentrio integration and does not affect any other GNSS vendor or modules + we have conducted internal testings. In addition this is a great feature which would add value to our receiver users)
