Defense Navigation Capabilities: DOD is Developing Positioning, Navigation, and Timing Technologies to Complement GPS GAO-21-320SP | Published: May 10, 2021; Publicly Released: May 10, 2021 Fast Facts DOD uses satellite-based GPS for critical operations with its aircraft, ships, munitions, land vehicles, and ground troops. DOD is developing positioning, navigation, and timing technology to complement GPS or as an alternative when GPS is unavailable. We looked at challenges DOD faces in developing and fielding these new technologies, and identified policy options to help address them. For example, the level of precision that GPS provides may not be needed for all applications. Clarifying [ READ MORE ]

Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing Services Executive Order 13905 of February 12, 2020 Excerpts: “By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows: Section 1. Purpose. The national and economic security of the United States depends on the reliable and efficient functioning of critical infrastructure. Since the United States made the Global Positioning System available worldwide, positioning, navigation, and timing (PNT) services provided by space-based systems have become a largely invisible utility for technology and infrastructure, including [ READ MORE ]

Protecting America’s Global Positioning System Spotlight | U.S. Department of Defense | June 26, 2020 Report excerpts: GPS At Risk The Defense Department opposes a license the Federal Communications Commission has granted to a private company, Ligado, to deploy a low-power nationwide mobile broadband network. Here’s why: GPS disruptions caused by Ligado interference could have global ramifications to U.S. national security, commercial and civil sectors, the economy, and those who rely on this service in their everyday lives. There are too many unknowns, and the risks are too great, to allow the proposed Ligado system to proceed. We risk lives [ READ MORE ]

DoD on Innovation Fast Track-Views of Top Pentagon PNT Managers Dee Ann Divis | December 20, 2019 | IG Inside GNSS Article excerpts: “Making sure that PNT capabilities are not lost due to jamming, spoofing or other disruptions is one of DOD’s highest overall priorities. For the Army in particular it’s an enabling capability for its top six modernization priorities, according to the newly released 2019 Army Modernization Strategy: Investing in the Future.” “Army PNT uses this approach to support development of a new PNT capability to reduce the weight, power requirements and collective space needed for GPS receivers and antennas.

Above Us Only Stars: Exposing GPS Spoofing in Russia and Syria C4ADS | March 2019 Executive Summary GPS and other Global Navigation Satellite Systems (GNSS) are used in everything from cellular communication networks, to basic consumer goods, high-end military systems, and stock trading inputs. But these systems are vulnerable: by attacking positioning, navigational, and timing (PNT) data through electronic warfare (EW) capabilities, state and non-state actors can cause significant damage to modern militaries, first-world economies, and everyday consumers alike. With recent technological advances, the tools and methodologies for conducting this interference are now at a high risk for proliferation. GNSS attacks [ READ MORE ]
