The navigational performance of an aircraft is dependent on two main factors: the navigation aids, whether ground or space-based, that are used, their geometry relative to the aircraft and the capabilities of the aircraft’s avionics.

The navigation domain addresses recent advances in navigation capabilities and the performance that can be delivered by the associated infrastructure. These advances include the development and introduction of performance-based navigation (PBN), which will enable improvements to be made in airspace design and will provide a far greater degree of flexibility in aircraft operations.

Ultimately, advanced navigation functionalities, with the support of appropriate ATM tools, will enable aircraft operators to conduct their flights in accordance with preferred trajectories, dynamically adjusted, in an optimum and cost-efficient manner.

GAELICAM has developed the following navigation courses:

N-GNSS: Global Navigation Satellite Systems (SBAS and GBAS).

This course explains GNSS systems comprising GPS, GLONASS, GALILEO and Beidou evolutions giving a general overview of signal processing in receiver, receiver performances (low-cost receiver vs. high-end receiver).

It also develops the signal structures and analyses system errors and augmentation.

N-PBN: implementing Performance Based Navigation.

Performance-based Navigation (PBN) is the most practical solution for the regulation of new navigation systems technology. This course explains the ICAO PBN concept and clarifies the differences between RNAV and RNP. PBN is based on Area Navigation, or RNAV, a method of navigation which permits aircraft operation on any desired flight path within coverage of station-referenced navigation aids or within the limits of the capability of self-contained aids, or a combination of these

It also provides detailed information on the 3 components of PBN: navigation applications, navigation specifications and navigation infrastructure. The course explains the concept, its enablers and provides detailed information on how to implement PBN.
