This
course provides an overview of both the Wide Area and Local Area
Augmentation Systems. WAAS and LAAS are high-integrity differential GPS
systems designed to complement each other in meeting the stringent
requirements necessary for safe aircraft navigation. The course focuses on
the development and understanding the operational requirements, as well as
the key system architectural elements of each system.
Note:
This course updates and integrates information previously available
through separate, independent tutorials on WAAS and LAAS (Trent Skidmore,
Ohio University). Course notes include material and updates provided by
Dr. Todd Walter, Stanford University. |
