Wärtsilä’s Develops Lock Entry Assist System

Wärtsilä said it has developed a lock entry assist system that will facilitate a vessel’s approach and entrance into waterway locks. The development work has been carried out in cooperation with the Canada-based CSL Group. The initial deployment of the technology will be on board the ‘CSL St Laurent’, a 22,600 gross tonnage Trillium class bulk carrier owned by CSL. The ship operates on the waterways of the St Lawrence Seaway and Great Lakes.The Wärtsilä system comes in response to the increasing size of vessels operating on these waters.

Britain Reviewing Risks to its Satellite-Reliant Infrastructure

Britain is reviewing its reliance on satellite-based technology for critical infrastructure including the Global Positioning System (GPS) as the threat of jamming attacks and disruptions grows, a government report said on Tuesday. Emergency services, transport, communications and financial networks are among key sectors which depend on Global Navigation Satellite Systems (GNSS) such as GPS. Such technology needs accurate and reliable position and timing signals. Experts say the problem with GNSS is their weak signals…

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…

Safety Alert: Global Navigation Satellite Systems

This past summer, multiple outbound vessels from a non-U.S. port suddenly lost GPS signal reception. The net effect was various alarms and a loss of GPS input to the ship's surface search radar, gyro units and Electronic Chart Display & Information System (ECDIS), resulting in no GPS data for position fixing, radar over ground speed inputs, gyro speed input and loss of collision avoidance capabilities on the radar display. Fortunately, the vessels were able to safely continue their voyage using radar in heads up display, magnetic compass and terrestrial navigation.

Lockheed Martin Awarded Contracts Two GPS lll Satellites

Lockheed Martin inform that the U.S. Air Force has awarded it more than $245 million in contract options to complete production of its seventh and eighth next-generation Global Positioning System satellites, known as GPS III. “With eight GPS III satellites now fully under contract, the GPS III program is moving from development into recurring production,” said Mark Stewart, vice president of Lockheed Martin’s Navigation Systems mission area. GPS III is an important program for the Air Force…

GPS lll Progress Report Update From Excelis

Exelis says it has successfully completed and fully tested six transmitter assemblies, which are integral payload components for the first in a series of the next generation of GPS III navigation satellites. The navigation payload transmitters carry high-powered GPS signals from space to Earth, benefitting military, commercial and civilian users. To ensure the space vehicle navigation payload meets performance requirements over the mission life, Exelis subjected the transmitter assemblies to a rigorous test program which includes random vibration…
