Compliance of Military GNSS Receivers for State Aircraft Operations in a PBN Environment

An innovative methodology

The introduction of performance-based navigation (PBN) in Europe raises the need to identify opportunities for compliance of State aircraft in order to fly in PBN airspace structures.

PBN specifies that performance requirements must be defined in terms of the accuracy, integrity, availability, and continuity required for the proposed operations in the context of a particular phase of flight or airspace area.

The majority of State aircraft are equipped with the Global Positioning System Precise Positioning Service (GPS PPS) to underpin the navigation function. The use of GPS PPS as the navigation sensor to perform PBN in airspace structures is crucial to enable State aircraft to fly in a general air traffic (GAT) environment which relies on such a system.

However, the compliance of on-board GPS PPS receivers with PBN system specifications has not yet been adequately qualified and demonstrated by both test and validation actions. Consequently, a methodology is required for GPS PPS receivers to attain certification-qualification on the basis of alternative means of compliance.
