US Coast Guard to Discontinue Remaining DGPS Sites

The U.S. Coast Guard announced today it will discontinue broadcasts from its remaining 38 Differential GPS (DGPS) sites over the next three years, completing system reductions that began in 2016. The staged reduction of the remaining Coast Guard DGPS broadcast sites will begin in 2018 and end with the last broadcast of GPS corrections over medium frequency in 2020. The U.S. Coast Guard Navigation Center has operated the Nationwide DGPS Service since 1999 to broadcast correction signals on marine radiobeacon frequencies to improve the accuracy and integrity to GPS-derived positions. Lt. Cmdr.

Cyber Threats Prompt Return of Radio for Ship Navigation

The risk of cyber attacks targeting ships' satellite navigation is pushing nations to delve back through history and develop back-up systems with roots in World War Two radio technology. Ships use GPS (Global Positioning System) and other similar devices that rely on sending and receiving satellite signals, which many experts say are vulnerable to jamming by hackers. About 90 percent of world trade is transported by sea and the stakes are high in increasingly crowded shipping lanes.

CORE EU Project: Assessing the Intermodal Supply Chain

The EU sponsored R&D project CORE (Consistently Optimized REsilient Secure Global Supply-Chains) began in 2014. Along the way, it analyzes the use of EGNOS and Galileo for the intermodal transport of dangerous goods, assessing its ability to deliver optimum safety, security and supply chain efficiencies. Every year, the transportation of dangerous goods amounts to approximately 150 billion tonne-km on European roads, railways and inland waterways. The safety and security of operations are common concerns and as such…

Garamendi Introduces Bipartisan GPS Backup Bill

Congressman John Garamendi (D-Fairfield, CA), the Ranking Member of the House Transportation and Infrastructure Subcommittee on the Coast Guard and Maritime Transportation, introduced the bipartisan National Positioning, Navigation, and Timing (PNT) Resilience and Security Act of 2015, H.R. 1678. H.R. 1678 would require the Secretary of Defense, in coordination with the Commandant of the Coast Guard and the Secretary of Transportation, to establish and sustain a reliable, land…

New Ship-based System Takes Out GPS Jamming Threat

With GPS jamming a growing worry for UK shipping, a new device seamlessly switches systems to counter the navigational menace. In development since 2005, the ACCSEAS project used a system on the vessel THV Galatea in the seas off Harwich to show that the PNT (Positioning, Navigation and Timing) technology was resilient enough to withstand the worst case scenario of a ship suddenly losing all GPS signals, reports PC Advisor. In theory it would be possible to simply turn off a GPS system and switch on the powerful…

China's GPS 'Beidou' to be Enhanced

The Third China Satellite Navigation Conference in progress in Guangzhou, South China’s Guangdong Province, with satellite experts, government officials and business executives from China, the US, Russia, Europe and Japan participating in the event.The Beidou system chief designer, Sun Jiadong, said China will expand the Beidou satellite navigation service across the entire country. Beidou is a satellite navigation system developed by China and has been providing services since the end of 2011.
