２０１５年１１月９日から一週間程度、米国スタンフォード大学よりSamuel P. Pullen博士を本研究室に外国人招聘研究員としてお招きします。滞在中には、学生への講義や下記の特別講演を予定しています。

【特別講演Ⅰ】
日　時： 11月12日（木）13:00 – 14:30 ［60 min. lecture + 30 min. discussion］
場　所： B6-105講義室
演　題： Safety Analysis and Verification for Users of Satellite Navigation Systems

講演概要：
This presentation explains how safety requirements are defined for users of Global Navigation satellite Systems (GNSS) such as GPS and shows how these requirements are incorporated into the design of GNSS and its augmentation. While today’s GNSS safety standards were derived from probabilistic risk principles and the design of earlier engineering systems, the properties of GNSS have led to a unique method of establishing safety in real time and protecting against failures that may come from many different sources.

演　題： Development of Ground-Based Augmentation of Global Positioning Systems:
Addressing the Key Challenges

講演概要：
This presentation gives an overview of how Ground-Based Augmentation Systems (GBAS) for GPS and other Global Navigation Satellite Systems (GNSS) were developed and how GBAS satisfies the safety and availability requirements for civil aviation and other users. GBAS is an application of differential GNSS technology and is based on the broadcast of pseudorange corrections and integrity information to users within 50 km of GBAS- quipped airports. The broadcast corrections allow users to remove common errors in GNAS ranging signals and reduce the resulting position errors to 0.5 m (95%) or less under nominal conditions. The associated integrity information allows users to exclude satellites with faulty ranging signals and limit the remaining satellites applied to the user’s position solution. For civil aviation users, the resulting performance is sufficient to support Category I precision approach operations today and Category II/III precision approach and landing operations in the next 5 to 10 years.
