The U.S. Department of Transportation’s most recent document preparing for the future of self-driving cars almost entirely ignores positioning, navigation and timing (PNT) needs, according to the Resilient Navigation and Timing (RNT) Foundation. And when it does address GPS, it gets things wrong. A Dec. 3 deadline looms for interested parties to file their comments with DOT.
The comment period is open until December 3. Interested parties can make their own comments and read those already submitted at the website for Docket DOT-OST-2018-0149.
The cited comment from the RNT Foundation states that, while most self-driving cars are being designed to navigate without external inputs, GPS/GNSS will still be required to initialize location information for vehicle cold startups. Also, most vehicles will reference GPS/GNSS when communicating their positions to other vehicles and traffic control systems.
Much of the benefit of automated vehicles will come from their participation in Intelligent Transportations Systems. This means wireless networks. The RNT Foundation also urges the department to consider these networks’ critical dependence on GPS timing synchronization in their plans going forward.

The U.S. Federal Communications Commission (FCC) granted in part the European Commission’s request for a waiver of the commission’s rules so that non-federal devices in the United States may access specific Galileo signals. While private users were free to use the European GNSS, with this ruling entities such as telecommunications companies can now also use Galileo.
With today’s action, consumers and industry in the United States will now be permitted to access the E1 and E5 Galileo signals to augment GPS.
Since the debut of the first consumer handheld GPS device in 1989, consumers and industry in the United States have relied on the U.S. GPS to support satellite-based positioning, navigation, and timing (PNT) services that are integral to everyday applications ranging from driving directions to precision farming.
The order, approved Nov. 15, finds that Galileo is uniquely situated as a foreign GNSS system with respect to the U.S. GPS, since the two systems are interoperable and radiofrequency compatible pursuant to the 2004 European Union/United States Galileo-GPS Agreement.
Specifically, the order permits access to two of the Galileo system’s satellite signals — the E1 signal that is transmitted in the 1559-1591 MHz portion of the 1559-1610 MHz Radionavigation-Satellite Service (RNSS) frequency band, and the E5 signal that is transmitted in the 1164-1219 MHz portion of the 1164-1215 MHz and 1215-1240 MHz RNSS bands. These are the same RNSS bands in which the U.S. GPS satellite signals operate.
The order does not grant access to the Galileo E6 signal, which is transmitted over the 1260-1300 MHz frequency band, since this band is not allocated for RNSS in the United States or used by the U.S. GPS to provide PNT services.
The commission noted that granting access to the Galileo E6 signal could constrain U.S. spectrum management in the future in spectrum above 1300 MHz, where potential allocation changes are under consideration.
The U.S. Maritime Administration issued an expanded advisory for GPS disruptions in the Middle East. The new advisory renews and repeats warnings for the eastern Mediterranean and adds the Port of Jeddah in Saudi Arabia.
Reports have also been filed with the U..S Coast Guard Navigation Center about disruptions in Israel’s Port of Haifa and the Straits of Hormuz.
Analysis by the Resilient Navigation and Timing Foundation and the non-profit firm C4ADS has also shown on-going disruptions in Russian waters of the Black Sea. Also, GPS jamming by Russia is suspected during a recent NATO exercise.
The armed conflict in Syria has been blamed for much of the disruptions off of its shores.
GPS jamming in support of illegal fishing is suspected by some as the cause of problems off of Port Said, and disputes over mineral rights has been suggested for the disruptions seen near Cyprus.
Disruptions in the Black Sea are suspected to be security measures associated with the travel of Russian government officials.

NATO conducted its largest military exercise since the Cold War in the frigid waters and icy mountains of Norway Oct. 25-Nov. 7.
During the final days of the Trident Juncture exercise, GPS signals guiding ships, aircraft, tanks, trucks and troops began to fail. Tracking screens flickered and positions were suddenly wrong from a few meters to hundreds of kilometers.
Civilian airliners, cars, trucks, cargo ships and smartphones operating in and around Norway and Finland experienced similar disruptions. Norway-based airline Wideroe told The Barents Observer that its pilots were reporting the loss of GPS signals when flying to airports in northern Norway and Finland. Airfields affected ranged from Kirkenes, on Norway’s border with Russia, to Lyngen in Troms, much further west.
Russia is the chief suspect of jamming the signals in reaction to the massive size and proximity of the military exercises. Russia also has recently conducted massive military exercises in the Baltics.
“It is possible that Russia has been the disrupting party in this,” Finland’s Prime Minster Juha Sipila told local media. “Russia is known to possess such capabilities.”
Trident Juncture involved all 29 NATO alliance members. Neutral Sweden and Finland also took part amid growing uncertainty over Russia’s ambitions in the tense region.

Wi-Fi capability within GPS 7500 allows for base-station configuration from a smartphone or tablet.When uptime is valued over absolute accuracy, integrated StableLoc technology utilizes available correction signals to provide a seamless transition between correction sources — without position jumps — and maximize signal uptime.
“SteerCommand with DualTrac brings a dual-antenna offering to the market that provides RTK accuracy and meets the needs of many farmers requiring high-accuracy automated steering at low speeds,” said Bill Cran, Ag Leader product specialist. “New GNSS technology in the GPS 7500 was leveraged to make this possible and also adds new satellite and correction offerings including TerraStar-C PRO.”
The GPS 7500 supports the new TerraStar-C PRO service, available in 3-month and 12-month subscriptions. TerraStar-C PRO offers multi-constellation/multi-frequency positioning with greater accuracy, availability and reliability than before. Its convergence is 60-percent faster and accuracy 40-percent better than TerraStar-C to overcome challenging signal conditions such as multipath, shading, interference and scintillation.
SteerCommand with DualTrac. Combining the GPS 7500 receivers with SteerCommand and InCommand displays offers automated steering control with sub-inch accuracy at ultra-low speed (as low as 0.05 mph). SteerCommand with DualTrac is designed for operations requiring precise steering such as planting or harvesting bedded crops, installing drip tape or planting and harvesting specialty crops. It provides a stable heading, even when the vehicle is not moving, as well as rapid line acquisition in forward or reverse.
