### Position Loss Failsafe Trigger
|
||||
|
||||
There are basically two mechanisms in PX4 to trigger position failsafes:
|
||||
|
||||
- A timeout since the last sensor data was fused that provides direct speed or horizontal position measurements. Sensors that fall into that category are: GNSS, optical flow, airspeed, VIO, auxiliary global position.
|
||||
- The estimated horizontal position accuracy exceeds a certain threshold. This check is only done on hovering systems (rotary wing vehicles or VTOLs in hover phase).
|
||||
|
||||
The relevant parameters shown below.
