The aviation industry has significantly benefited from satellite navigation services, with the importance of GNSS set to continue to grow.
In particular, the Safety-of-Life functionality of EGNOS has helped to improve safety and efficiency of secured landing approaches at European airports. This service ensures that the EGNOS navigation message includes an integrity function, which can warn pilots within 6 seconds in case of a malfunction. EGNOS has already been certified to enable aircraft landing navigation down to a decision height of 200 feet (LPV-200).
Further uses of EGNOS and Galileo may help in supporting the new Performance-Based Navigation goals of the EU across all flight segments, as defined in Commission Implementing Regulation (EU) 2018/1048. In addition, Galileo can support Search-and-Rescue operations via the detection of activated rescue beacons. The information provided by GNSS can also improve air traffic management operations via ADS-B (Automatic Dependent Surveillance Broadcast) tracking, which can improve monitoring and planning of aircraft operations.
GNSS-enabled device sales have seen an unprecedented growth in both general and commercial aviation, with growth in Asia-Pacific markets a key contributor to this trend.
