## Position (GNSS) Loss Failsafe
-The _Position Loss Failsafe_ is triggered if the quality of the PX4 global position estimate falls below acceptable levels (this might be caused by GPS loss) while in a mode that requires an acceptable position estimate.
+The _Position Loss Failsafe_ is triggered if the quality of the PX4 position estimate falls below acceptable levels (this might be caused by GPS loss) while in a mode that requires an acceptable position estimate.
+The sections below cover first the trigger and then the failsafe action taken by the controller.
+
+### 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.
+
+| Parameter | Description |
+| -------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
+| [EKF2_NOAID_TOUT](../advanced_config/parameter_reference.md#EKF2_NOAID_TOUT) | Maximum inertial dead-reckoning time, so the time after the last data sample was received of any sensor that constrains the velocity drift [microseconds]. |
+| [COM_POS_FS_EPH](../advanced_config/parameter_reference.md#COM_POS_FS_EPH) | Horizontal position error threshold for hovering vehicles (Multicopters and VTOLs in hover). Fixed-wing vehicles have this value set to infinity.|
+
+### Position Loss Failsafe Action
The failure action is controlled by [COM_POSCTL_NAVL](../advanced_config/parameter_reference.md#COM_POSCTL_NAVL), based on whether RC control is assumed to be available (and altitude information):

- * Horizontal position error threshold.
+ * Horizontal position error threshold for hovering systems
*
* This is the horizontal position error (EPH) threshold that will trigger a failsafe.
- * The default is appropriate for a multicopter. Can be increased for a fixed-wing.
* If the previous position error was below this threshold, there is an additional
* factor of 2.5 applied (threshold for invalidation 2.5 times the one for validation).
+ * Only used for multicopters and VTOLs in hover mode.
+ * Independent from estimator positioning data timeout threshold (see EKF2_NOAID_TOUT).
*
* Set to -1 to disable.
