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.

GPS Option Available on AIS

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.

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.

Marine Television May Interfere with Navigation Systems

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.

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.

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…

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, 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.

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.
