(2)
ensure that United States armed forces have the capability to use the GPS effectively despite hostile attempts to prevent the use of the system by such forces.
(b) Sustainment and Operation for Civilian Purposes.—The Secretary of Defense shall provide for the sustainment and operation of the GPS Standard Positioning Service for peaceful civil, commercial, and scientific uses on a continuous worldwide basis free of direct user fees. In doing so, the Secretary—
(1)
shall provide for the sustainment and operation of the GPS Standard Positioning Service in order to meet the performance requirements of the Federal Radionavigation Plan prepared jointly by the Secretary of Defense and the Secretary of Transportation pursuant to subsection (c);
(2)
shall coordinate with the Secretary of Transportation regarding the development and implementation by the Government of augmentations to the basic GPS that achieve or enhance uses of the system in support of transportation;
(3)
shall coordinate with the Secretary of Commerce, the United States Trade Representative, and other appropriate officials to facilitate the development of new and expanded civil and commercial uses for the GPS;
(4)
shall develop measures for preventing hostile use of the GPS in a particular area without hindering peaceful civil use of the system elsewhere; and
(5)
may not agree to any restriction on the Global Positioning System proposed by the head of a department or agency of the United States outside the Department of Defense in the exercise of that official’s regulatory authority that would adversely affect the military potential of the Global Positioning System.
(c) Federal Radionavigation Plan.—
The Secretary of Defense and the Secretary of Transportation shall jointly prepare the Federal Radionavigation Plan. The plan shall be revised and updated not less often than every two years. The plan shall be prepared in accordance with the requirements applicable to such plan as first prepared pursuant to section 507 of the International Maritime Satellite Telecommunications Act[1] (47 U.S.C. 756). The plan, and any amendment to the plan, shall be published in the Federal Register.
(d) Definitions.—In this section:
(1) The term “basic GPS services” means the following components of the Global Positioning System that are operated and maintained by the Department of Defense:
(A)
The constellation of satellites.
(B)
The navigation payloads that produce the Global Positioning System signals.
(C)
The ground stations, data links, and associated command and control facilities.
(2)
The term “GPS Standard Positioning Service” means the civil and commercial service provided by the basic Global Positioning System as defined in the 1996 Federal Radionavigation Plan (published jointly by the Secretary of Defense and the Secretary of Transportation in July 1997).

Sustainment and Operation of Global Positioning System

Pub. L. 105–85, div. A, title X, § 1074(a), (b), Nov. 18, 1997, 111 Stat. 1907, provided that:

“(a) Findings.—Congress makes the following findings:
“(1)
The Global Positioning System (consisting of a constellation of satellites and associated facilities capable of providing users on earth with a highly precise statement of their location on earth) makes significant contributions to the attainment of the national security and foreign policy goals of the United States, the safety and efficiency of international transportation, and the economic growth, trade, and productivity of the United States.
“(2)
The infrastructure for the Global Positioning System (including both space and ground segments of the infrastructure) is vital to the effectiveness of United States and allied military forces and to the protection of the national security interests of the United States.
“(3)
In addition to having military uses, the Global Positioning System has essential civil, commercial, and scientific uses.
“(4) As a result of the increasing demand of civil, commercial, and scientific users of the Global Positioning System—
“(A)
there has emerged in the United States a new commercial industry to provide Global Positioning System equipment and related services to the many and varied users of the system; and
“(B)
there have been rapid technical advancements in Global Positioning System equipment and services that have contributed significantly to reductions in the cost of the Global Positioning System and increases in the technical capabilities and availability of the system for military uses.
“(5) It is in the national interest of the United States for the United States—
“(A)
to support continuation of the multiple-use character of the Global Positioning System;
“(B)
to promote broader acceptance and use of the Global Positioning System and the technological standards that facilitate expanded use of the system for civil purposes;
“(C)
to coordinate with other countries to ensure (i) efficient management of the electromagnetic spectrum used by the Global Positioning System, and (ii) protection of that spectrum in order to prevent disruption of signals from the system and interference with that portion of the electromagnetic spectrum used by the system; and
“(D)
to encourage open access in all international markets to the Global Positioning System and supporting equipment, services, and techniques.
“(b) International Cooperation.—Congress urges the President to promote the security of the United States and its allies, the public safety, and commercial interests by taking the following steps:
“(1)
Undertaking a coordinated effort within the executive branch to seek to establish the Global Positioning System, and augmentations to the system, as a worldwide resource.
“(2)
Seeking to enter into international agreements to establish signal and service standards that protect the Global Positioning System from disruption and interference.
“(3)
Undertaking efforts to eliminate any barriers to, and other restrictions of foreign governments on, peaceful uses of the Global Positioning System.
“(4)
Requiring that any proposed international agreement involving nonmilitary use of the Global Positioning System or any augmentation to the system not be agreed to by the United States unless the proposed agreement has been reviewed by the Secretary of State, the Secretary of Defense, the Secretary of Transportation, and the Secretary of Commerce (acting as the Interagency Global Positioning System Executive Board established by Presidential Decision Directive NSTC–6, dated March 28, 1996).”
Access to Global Positioning System

Pub. L. 104–106, div. A, title II, § 279, Feb. 10, 1996, 110 Stat. 243, provided that:

“(a) Conditional Prohibition on Use of Selective Availability Feature.—
Except as provided in subsection (b), after May 1, 1996, the Secretary of Defense may not (through use of the feature known as ‘selective availability’) deny access of non-Department of Defense users to the full capabilities of the Global Positioning System.
“(b) Plan.—Subsection (a) shall cease to apply upon submission by the Secretary of Defense to the Committee on Armed Services of the Senate and the Committee on National Security of the House of Representatives of a plan for enhancement of the Global Positioning System that provides for—
“(1)
development and acquisition of effective capabilities to deny hostile military forces the ability to use the Global Positioning System without hindering the ability of United States military forces and civil users to have access to and use of the system, together with a specific date by which those capabilities could be operational; and
“(2)
development and acquisition of receivers for the Global Positioning System and other techniques for weapons and weapon systems that provide substantially improved resistance to jamming and other forms of electronic interference or disruption, together with a specific date by which those receivers and other techniques could be operational with United States military forces.”
Limitation on Procurement of Systems Not GPS-Equipped

Pub. L. 103–160, div. A, title I, § 152(b), Nov. 30, 1993, 107 Stat. 1578, as amended by Pub. L. 105–261, div. A, title II, § 218(e), Oct. 17, 1998, 112 Stat. 1952; Pub. L. 109–163, div. A, title II, § 260(a), Jan. 6, 2006, 119 Stat. 3185, provided that:
