GNSS degradation may not change the aircraft behaviour or operation.
GNSS loss will prevent GNSS features from functioning.
GNSS degradation can be identified by:
- Signal bars on the Command Unit (CU) display
- Voice alerts from the CU
- Drift in UAS position
- Reduction in accuracy of the UA flight path
GNSS loss is characterised by:
- Alerts
- Change in UAS behaviour
- Stops mid flight
- Position drifts due to wind
- Loss of position hold flight mode
