The study was conducted in the first half of 2016 with a view to describing the operational context and system options for the integration of State aircraft into a Single European Sky ATM Research (SESAR) operational environment by:
- integrating results from a previous military study on GNSS (Global Navigation Satellite System): Multi-constellation Precise Signals for State Aircraft;
- providing a detailed and comprehensive State aircraft Flight Trial Campaign (FTC) specification, when using GNSS restricted signals for navigation in a PBN (Performance Based Navigation) application context and in a mixed-mode environment.
The outcome of this study led to a technical contribution to SESAR Project 9.27 (Multi-constellation GNSS Airborne Navigation Systems).
The flight trial campaign was aimed at the subsequent potential integration and execution of multi-constellation GNSS airborne navigation systems in the SESAR 2020 Work Programme – Very Large Scale Demonstrations or any other relevant validation/demonstration initiatives.
