LAAS Study of Slow-Moving Ionosphere Anomalies and Their Potential Impacts
Ionosphere Anomalies Potential Impacts
2015/6/26
Triggered by several severe ionosphere storms that have occurred in recent years, research has been done to studying those anomalies, the physics behind them, and their potential impact on augmented G...
Prior Probability Model Development to Support System Safety Verification in the Presence of Anomalies
Prior Probability Model Development Support System Safety Verification
2015/6/26
Assessments of “prior probabilities” of faults that must be mitigated are essential to integrity and safety verification for safety-critical systems. In the case of Global Navigation Satellite System ...
The Impact and Mitigation of Ionosphere Anomalies on Ground-Based Augmentation of GNSS
Ionosphere Anomalies Ground-Based Augmentation GNSS
2015/6/25
This paper describes the impact that extreme ionospheric spatial gradients occurring during severe ionosphere storms have on GNSS Ground Based Augmentation Systems (GBAS) and how the U.S. Local Area A...
Long Term Monitoring of Ionospheric Anomalies to Support the Local Area Augmentation System
Long Term Monitoring Ionospheric Anomalies Local Area Augmentation System
2015/6/25
Extremely large ionospheric gradients can pose a potential integrity threat to the users of Local Area Augmentation System (LAAS), and thus the development of an ionospheric anomaly threat model is es...
