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.

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.

Saab TransponderTech introduced a new type-approved GPS as an integrated part of the R4 ship AIS transponder system. Gunnar Mangs, business director for mobile systems, said, “This fully compliant GPS receiver is intended to provide a fully qualified backup to the SOLAS class ship’s main DGPS, and adds GPS navigation functionality to the AIS transponder. The GPS receiver is embedded inside the R4 transponder. It provides the necessary GPS outputs to the AIS, and also provides navigation functions on the R4 display unit.

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.

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.

The U.S. Coast Guard warns all mariners that certain marine television antennas may interfere with the performance of Global Positioning System receivers. The interference can result in inaccurate position information or a complete loss of GPS signals. This is a potential hazard to navigation, for both the operator of the vessel with the television antenna and for nearby boaters as the interference is not limited to the GPS equipment onboard the vessel with the antenna. In some cases, vessels up to 2000 feet away from an active antenna have reported interference. If mariners experience outages or degradation of their GPS receiver operation, they should perform an on-off test of their marine TV antenna.

RedPort Global, providers of marine satellite data, voice routers and services, launch GPS tracking service with the RedPort Optimizer. 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.

The U.S. Air Force has awarded Lockheed Martin more than US$200-million in contract options to complete production of its fifth and sixth next-generation Global Positioning System satellites, known as GPS III . Lockheed Martin explain that the GPS III improves capability to meet the evolving demands of military, commercial and civilian users. GPS III satellites will deliver three times better accuracy; provide up to eight times improved anti-jamming capabilities; and include enhancements which extend spacecraft life 25 percent further than the prior GPS block.

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…

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.

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, longwave eLoran (eLOng RAnge Navigation), but in the middle of a busy shipping lane sea captains don't necessarily realise what is happening to them quickly enough.

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…

Marine safety products manufacturer Vesper Marine has released a new Class B Automatic Identification System (AIS), the XB-6000. The black box transponder includes a built-in NMEA 2000 gateway and GPS antenna that integrates AIS, GPS and NMEA instrument data to display vital safety information on any AIS-compatible chartplotter, multifunction display (MFD) or personal computer. The Vesper Marine XB-6000 offers convenient access to AIS safety information instantaneously while on the water.

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.
