Pursuant to a congressional request, GAO reviewed the Federal Aviation Administration's (FAA) augmentation of the Global Positioning System (GPS) for use in civil aviation navigation, focusing on whether FAA: (1) will have sufficient time under its new milestones to augment GPS; and (2) has taken appropriate actions to better manage its GPS-related efforts.
Recommendations for Executive Action
|Department of Transportation||1. The Secretary of Transportation should direct the Administrator, FAA, to prepare a comprehensive plan for augmenting GPS and transitioning to it and to update this plan regularly. The plan should include, among other things, schedule and cost estimates for developing and implementing the wide and local area augmentation systems as well as information on the probability that FAA will meet these estimates.|
