| Popis: | The consequences of GPS L1 C/A signal distortions due to payload failure on a civil aviation GPS user has received a lot of attention in the late 1990’s and early 2000 following the occurrence of a first such event in 1993. The result of the corresponding work led to the characterization and modeling of such a threat, known as Threat Model (TM), and the development of means to mitigate this threat in SBAS and GBAS, known as Signal Quality Monitoring (SQM). The proposed TM, endorsed by International Civil Aviation Organization (ICAO), is adapted to the GPS L1 C/A signal and derived from the observations of the 1993 event as well as other considerations. However, with the evolution of the payloads over the years, the multiplication of GNSSs, and the multiplication of modulations used by GNSS signals, the adaptation of this TM to other signals and systems might not be straight-forward: the a priori identification of the effect of a payload failure on the transmitted signal is a very complicated task. The objective of this paper is thus to investigate another TM, referred to as generic TM, that could cover a large threat space and that could be adapted to other signals. This generic TM could be for instance used by future Dual-Frequency Multi-Constellation SBAS to protect the use of new GNSS signals. The article thus investigates such generic TM in the specific case of Galileo E1C and its impact on an associated SQM. |
