First, the complemen tary roles of the Wide Area Augmentation System (WAAS) and LAAS are su mmarized. Then technical activities are discussed, including requireme nts, system architecture, and fight tests. The paper concludes with a summary of the FAA's plans for LAAS, including the planned schedule of major programme activities.
