GPS Modernization: DOD Continuing to Develop New Jam-Resistant Capability, But Widespread Use Remains Years Away [GAO-21-145] Published: Jan 19, 2021; Publicly Released: Jan 19, 2021. View the full GAO report, 55 pages > Fast Facts GPS may seem like everyday technology, but it depends on military systems that continue to evolve to meet defense needs. The Department of Defense has worked for decades to develop a jam-resistant GPS capability for the military called M-code. This requires satellites to broadcast the M-code signal, control systems on the ground, and equipment that can receive it. Modernized satellites are in space but receiver [ READ MORE ]

We Need a Backup for GPS. Actually, We Need Several of Them The key is incentivizing adoption of position-navigation-timing alternatives. By Robert Cardillo, Distinguished Fellow, CSET | December 1, 2020 | Defense One COMMENTARY C4ISR Article Excerpts: “Creating a backup to the GPS constellation has been federal policy since 2004, when President George W. Bush’s National Security Policy Directive-39 ordered the Pentagon to redouble efforts to counter jamming and other interferences and to ensure uninterrupted access to the positioning, timing, and navigation signals that undergird so many of our society’s vital functions. But although much progress has been made since then, the [ READ MORE ]

The Russians are screwing with the GPS system to send bogus navigation data to thousands of ships Jim Edwards | April 14, 2019 | Business Insider Article excerpts: “‘All critical national infrastructures rely on GNSS to some extent’ — and the Russians have started hacking it…” ”GNSS comprises the constellation of international satellites that orbit Earth. The US's Global Positioning System, China's BeiDou, Russia's Glonass, and Europe's Galileo program are all part of GNSS. Your phone, law enforcement, shipping, airlines, and power stations — anything dependent on GPS time and location synchronization — are all vulnerable to GNSS hacking. A [ READ MORE ]
