* docs(releases): draft v1.17.0 release notes
Drafts the v1.17.0 release notes based on commits in the
release/1.16..release/1.17 diff, with every PR citation verified as an
ancestor of release/1.17 and not shared with release/1.16.
Major Changes leads with the experimental MC Neural Network Control
mode and the on-device TFLM integration, the new Altitude Cruise mode
for multicopters, FW Takeoff improvements, FW and Rover ROS 2 Control
Interface setpoints, and the in-tree Zenoh middleware maturing toward
rmw_zenoh compatibility.
Hardware Support is reorganized into four sub-groups: New Flight
Controllers, New Build Targets for Existing Hardware, New CAN
Peripherals & Vehicle Platforms, and Existing Boards: Improvements.
The Simulation section is split into Gazebo and SIH sub-groups. The
ROS 2 / DDS section is split into uXRCE-DDS and Zenoh.
Posted on main as a draft to give docs maintainers visibility and
collect review feedback. Backport strategy to release/1.17 (alpha/beta
banner variant vs the stable banner variant on main) is a follow-up
discussion.
Also fixes a long-anchor scroll-restoration bug in
px4_ros2_control_interface.md by giving the FwLateralLongitudinal
heading an explicit short anchor (#fw-lateral-longitudinal-setpoint),
and updates the corresponding link in releases/main.md.

* docs(releases): address review on v1.17.0 notes
- Cross-link Altitude Cruise in the intro paragraph.
- Reframe MC Neural Network Control as an experimental test path
rather than first-class on-device inference; move it to the bottom
of Major Changes.
- Drop the redundant "opt-in" wording from the Zenoh Major Changes
bullet.
- Rewrite Upgrade Guide as a true upgrade procedure (actionable
numbered steps with what to do and why) following the v1.14 release
notes pattern instead of a flat parameter-delta list.
- Add the missing PR reference for the extended MISSION_CURRENT entry
(#25034, populating the MAVLink mavlink/mavlink#1869 fields).
- Dedupe Safety / Commander against Common: failsafe takeover,
Offboard-to-Position-without-RC, and motor-failure timeout checks
are now listed only once in Common.

* feat(gpsRedundancyCheck): add GPS redundancy failsafe with divergence check
- Monitors GPS count and triggers configurable failsafe (COM_GPS_LOSS_ACT) when count drops below SYS_HAS_NUM_GPS
- Tracks online (present+fresh) and fixed (3D fix) receivers separately; emits "receiver offline" vs "receiver lost fix"
- Detects position divergence between two receivers against combined RMS eph uncertainty plus lever-arm separation
- Pre-arm warns immediately; in-flight requires 2s sustained divergence to suppress multipath false alarms
- Adds GpsRedundancyCheckTest functional test suite
New parameters: SYS_HAS_NUM_GPS, COM_GPS_LOSS_ACT
* feat(sensor_gps_sim): publish second GPS instance using SENS_GPS1 lever arm params
When SENS_GPS1_OFFX or SENS_GPS1_OFFY is non-zero, publish a second sensor_gps instance offset by those values from the vehicle position.
fix(sensor_gps_sim): give second instance distinct device_id
Both simulated GPS instances previously shared the same device_id (address 0x00). This prevented testing the device-ID matching path in SITL since both slots would match the same receiver.
* refactor(gpsRedundancyCheck): address code review feedback
* refactor(gpsRedundancyCheck): address code review feedback
* docs: add GNSS check failsafe documentation
Update safety.md and releases/main.md to document the new GNSS check
failsafe (SYS_HAS_NUM_GNSS, COM_GPS_LOSS_ACT) introduced in PX4.
* docs(update): Subedit to taste
* refactor(gps): move GNSS redundancy detection into sensors module
Add GnssRedundancyStatus topic and GnssRedundancyMonitor in
vehicle_gps_position. Commander's gpsRedundancyCheck becomes a thin
consumer of the new topic. Detection lives with blending/fallback in
one module.
Also rename COM_GPS_LOSS_ACT -> COM_GNSS_LSS_ACT.
* docs(safety): clarify GNSS failsafe wording and rename COM_GNSS_LSS_ACT
* refactor(failsafe): consistent default case as fallback for existing option
* Rename COM_GNSS_LSS_ACT -> COM_GNSSLOSS_ACT
for readability
* fix(gnssRedundancyCheck): move logic back into the commander checks and various improvement suggestions
- Rename to GNSS instead of gps
- Use hysteresis
- Small logic refactorings
- Adapt unit tests to different interface
- User reporting on which GPS is offline or doesn't have a fix
* docs(gnssRedundancyCheck): simplify explanations
* refactor(gnssRedundancyCheck): update year numbers in copyright

* SITL: mavlink bind to a specific interface using an environment variable PX4_NET_INTERFACE
Fixes issue #26384
* document the usage of PX4_NET_INTERFACE
* Improved Docs:
- Added new Environment Configuration subsection at the end of SITL Simulation
- Removed the old Bind MAVLink to Specific Network Interface subsection (content consolidated into the new section)
