Defense Navigation Capabilities: DOD is Developing Positioning, Navigation, and Timing Technologies to Complement GPS
Abstract
For decades, the satellite-based GPS has transmitted PNT data to receivers used by military platforms and personnel worldwide. PNT information is essential in many facets of DOD operations. Given the ubiquity of GPS, the failure, malfunction, or jamming of its signals or equipment could disrupt military activities involving aircraft, ships, munitions, land vehicles, and ground troops. This possibility has led DOD to explore alternatives to GPS. GAO was asked to assess the alternative PNT technologies DOD is developing. This report discusses (1) how DOD plans to meet future PNT needs and the capabilities and limitations of alternative PNT technologies, (2) how alternative PNT technologies integrate with one another and with current PNT capabilities, and (3) policy options that may help address challenges with the development and integration of alternative PNT technologies. To address these objectives, GAO reviewed technical studies, agency documents, and other key reports; interviewed government officials and researchers about alternative PNT technologies; and convened a 3-day meeting of experts from government, non-governmental organizations, academia, and industry. GAO is identifying policy options in this report.
