Ships exposed through GPS systems, have limited back-up; cyber insurance typically doesn't cover jamming, property damage. Shipping companies grappling with the threat of cyber attacks on vessels are finding insurance policies often fall short, officials involved in both industries say, a risk that could feed through into global prices. Digitalisation means electricity networks, emergency services, industry and agriculture are all vulnerable to hacking by criminal gangs for extortion or, for political reasons, by militant groups or foreign states.

USCG Advisory: Upgrade to GPS enhanced EPIRBs

When Emergency Position Indicating Radio Beacons (EPIRB) are activated in emergency situations the system transmits vessel identification information to rescuers. Traditional EPIRBs rely on satellite Doppler Shift to identify the distress location. There are a wide  variety of Coast Guard approved EPIRBs on the market but many do not have the most up-to-date feature: the  ability to transmit the EPIRB’s GPS location. Several recent casualty investigations have revealed that EPIRB owners are largely unaware that rescue efforts are significantly improved and your vessel’s location transmitted more quickly and accurately when distress signals are initiated by  GPS enhanced EPIRBs. GPS enhanced EPIRBs normally save 30 to 100 minutes in obtaining an accurate location.

Leica and NovAtel Will Develop Technologies For GPS

Leica Geosystems and NovAtel Inc. have entered an agreement to develop new technologies for global positioning systems (GPS). This is particularly relevant for equipment that will be based on the new upcoming Global Navigation Satellite Systems (GNSS). In the mid-eighties Leica Geosystems was one of the first companies to develop and market GPS surveying systems. NovAtel, founded in 1978, also has the reputation of being one of the most successful innovators of advanced concepts in GPS technologies. These include significant contributions to the development of Satellite Based Augmentation Systems (SBAS) such as WAAS, MSAS and EGNOS.

Comments Requested on GPS Interference

The USCG is requesting information from vessel operators on problems with, and potential solutions to, GPS system interference. The USCG states mobile telephones and other electronic devices employing Mobile Satellite Services (MSS) can interfere with GPS systems. This interference has the potential to adversely affect the safe navigation and operation of vessels using GPS technology. These problems resulted from the assignment of adjacent radio frequencies to MSS and GPS systems. Because of the proximity of their radio frequencies, the relatively high powered MSS transmissions can interfere with GPS receivers. One possible solution being considerd would be the limitation or restriction of MSS on certain maritime vessels…

GPS Spoofing and the Potential Perils to Ships at Sea

Simple annoyance or potential security threat? Spoof is defined as “a hoax or swindle.”  In the world of electronic networks, a spoofing attack is a situation in which one program successfully masquerades as another by falsifying data and thereby gaining an improper advantage. We have all heard of, and possibly fallen victim to, fraudulent card readers (often inserted on self-service fuel pumps). The fraudulent card readers copy security information from the credit card, which is then used to clone an illegitimate credit card and incur improper charges on the victim’s credit card account.

USCG – GPS testing off North Carolina

The USCG Navigation Center (NAVCEN) has issued a special notice stating that, from 3 through 10 February daily from 1600 EST to 2145 EST, the GPS navigation signal in waters off Wilmington, North Carolina may be unreliable due to testing of GPS signals used by shipboard, aviation, and handheld navigation devices. From Feb 03 through Feb 10, 2012, daily from 1600 EST to 2145 EST, the GPS navigation signal may be unreliable due to testing on GPS frequencies used by shipboard navigation, aviation and handheld systems. Systems that rely on GPS, such as E-911, AIS and DSC may be affected at an approximate testing center point of 33 45.00N, 77 00.00W, with an impact radius of approximately 75 NM from center point.

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.

Balancing Efficiency & Security as Maritime Goes Digital

In December 2004, Crew members assigned to the guided missile cruiser USS Yorktown (CG 48) man the rails for the final time in preparation of the order to de-man the ship as she is decommissioned on board Naval Station Pascagoula, Miss. In 1996, the Yorktown was selected to be the testbed for Navy’s Smart Ship program, effectively exposing a major flaw in the system when a simple error left the ship blacked out for hours.

Hand in hand with the digital craze in maritime is the caution of cyber attacks. We live and operate in a complex society. That society would be impossible without modern computers and other information technologies Those technologies have largely been developed piecemeal to address particular issues, and for the most part they have generally achieved their particular goals. Maximum efficiency is gained when multiple technologies are joined to coordinate their work. Computers get smaller and faster, with ever-growing memory. Joining computers together allowed for creation of the internet.

There are countless examples of how an over reliance of GPS navigation and the electronic charting systems, as well as the use of dead reckoning without a known fixed starting point – instead “eyeballing” the situation – are leading vessels in to danger. August 21, 2017 was the Great American Eclipse, and the science fiction fantasy fan in me wondered if this is when I would get my superpowers back. The navigator in me pondered if I was in the zone of totality and took a sight of the sun and moon, at the moment of totality would it count as two lines of position on my chart.

When connected to a GPS-enabled satellite phone or terminal, Optimizer works as a GPS Satellite Tracker , and can transmit the device’s GPS location at user-defined intervals, working with select tracking services to let users view GPS locations online or input them directly into their existing tracking systems. “Reliable, affordable GPS vessel tracking is a critical part of any vessel operations – from the smallest boat to the largest ship,” said Dr.

Safeguarding GPS When Global Positioning Doesn’t Work

Entrance to the U.S. Coast Guard Navigation Center.

Suppose the Global Positioning System (GPS) receivers used for your vessel, offshore oil platform, or port facility could not generate position data needed for your operations. How would your crew or staff respond? Initial troubleshooting efforts may indicate equipment failures, antenna masking, or possibly human error. Additionally, the lack of position data will likely force your crew or staff to resort to secondary means to obtain position information. If position data cannot be regained, then the receivers may have lost GPS due to intentional or unintentional interference.

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. “GPS provides sufficient positional accuracy to meet navigation requirements for harbor approaches and to position Federal Aids to Navigation,” Patterson said.
