Ground-Based Augmentation Systems (GBAS) enable terminal operations using GPS for navigation. The full GNSS constellation is envisioned to supplement GPS in the future. A critical condition for the use of satellite-based navigation in terminal areas is the availability of the system, in addition to the accuracy. The ionosphere can be populated by phenomena known as Traveling Ionospheric Disturbances (TIDs). TIDs have been studied for many years and are a concern for safe navigation. They are a threat to safe landings and takeoffs. ASTRA has developed the ability to detect TIDs with ground-based instruments, and has the expertise to make that information useful to ANSPs and airlines. The presentation will focus on the technology, the method, and the value of the information to the aviation community.
