Tetra Tech Inc. has announced it was awarded the rebid to the Global Positioning System Technical Assistance Contract 2 (GPS TAC2) with the Federal Aviation Administration, its largest contract with the agency. This follow-on agreement is worth approximately $60 million over two base years and one option year.
Tetra Tech's work helps the FAA capitalize on GPS technology advancements to allow for greater civilian air travel density and to provide greater worldwide accuracy, availability and integrity of navigation information. Tetra Tech will provide a full range of technical engineering and business support services to help manage the FAA's current and future satellite navigation system needs.
Tetra Tech has supported the FAA as the prime contractor for a predecessor to the GPS TAC2 contract for the past seven years. Under the predecessor contract, Tetra Tech provided comprehensive acquisition support services for the world's first satellite navigation system used for civilian aviation.
The Wide Area Augmentation System helped improve navigation signal accuracy from 65 feet (20 meters) to as close as five feet (1.5 meters) accuracy in both horizontal and vertical dimensions.
