The Instrument Landing System (ILS) is the current primary landing guidance system worldwide. The Microwave Landing System (MLS) may also become important in the future. Since proper guidance is extre...
Maintaining the accuracy of an Instrument Landing System (ILS) is very important because it is the primary landing guidance system during bad weather in the U.S. Therefore, the FAA periodically checks...
This paper presents novel Global Navigation Satellite System (GNSS)-based flight inspection systems (FIS) that outperform current flight inspection systems in terms of cost, efficiency, and integrity.
