Highlights
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
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Department of Transportation | 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. |
Closed – Implemented
The agency completed a GPS Transition Plan in July 1996. In addition, in January 1998, FAA completed work on an integrated GPS augmentation systems baseline investment plan. The plan includes schedule and cost estimates for developing and implementing the wide and local area augmentation systems and probability information on whether cost estimates will be met.
