    Dozens Stranded in Tundra

    Several vehicles in Rock Springs, Wyoming, were stranded after being led by their map apps or vehicle navigation systems to an unmaintained county road in a blizzard. Several calls were made to the Sweetwater County Sheriff’s Office about stranded vehicles stuck after they were directed to the detour when Interstate 80 was closed due to winter conditions. Similar incidents were reported by other counties, resulting in discussions between the Wyoming Department of Transportation and the companies that develop navigation software.

    UAVs contain Western Technology

    A Ukrainian intelligence assessment obtained by CNN and CBS reported an Iranian UAV downed in Ukraine contained technology from companies in the United States and other western countries. The White House has since launched an investigation as to how the technology — including semiconductors, GPS modules and engines — were obtained by Iran. The components removed from an Iranian Shahed-136 UAV totaled 52, 40 of which were manufactured by 13 different U.S. companies. The remaining components were manufactured by other western companies and by companies based in Japan, Taiwan and China.

    Machine learning helps monitor hurricanes

    Researchers may now be able to monitor climate-induced natural hazards by combining satellite technology with machine learning. Researchers were able to use machine learning to study hurricanes that made landfall over the Gulf of Mexico in a series of recent experiments. C.K. Shum, the co-author of the study and a professor at the Byrd Polar Research Center, uses geodesy to study global climate change phenomena. Using geodetic data gathered from satellites, Shum tested whether a mix of remote sensing and machine learning analytics could accurately monitor weather phenomena. Accurate measurements could help improve hurricane forecasting.

    The power of TikTok is real

    TikTok changed Jeff Foulk’s life when his daughter posted about his free marine navigation app, Argo, when they attended a boat show in Chicago. Foulk was promoting Argo with little success, until his daughter shared with the social media platform his struggle as the owner of a small business. Since then, the app has been downloaded more than 200,000 times and remains at the top of the charts for boat navigation apps. Argo was launched more than four years ago and, until now, had only 100,000 total downloads. Now that Argo is viral, Foulk wants to launch a premium subscription.

    Queue Tracker for the Queen

    After the passing of Queen Elizabeth II on Sept. 8, the British government launched a live queue tracker app to give people an idea how long they would have to wait to pay their respects at her lying in state at the Palace of Westminster. The app also used What3Words to help locate the end of the line using a three-word tag. The queue grew dramatically in the days before the funeral as tens of thousands lined up, some waiting as long as 16 hours. The app also showed locations of public toilets, drinking water and first-aid stations along the queue route.

    A Dam Problem Solved

    Lake Sarez, deep in the Pamir mountains of Tajikistan, was created only a century ago when a strong earthquake triggered a massive landslide. The area experiences considerable seismic activity, which could result in massive flooding downstream should a landslide dam break. With the help of 40 donkeys, 10 scientists and 30 staff from the National Time Service Center of the Chinese Academy of Sciences transported and installed a BeiDou-based deformation monitoring system at the dam. The team had to resolve technical problems in the rugged area, such as providing sufficient solar power and communications. With the system now operating, the dam is being monitored in real time down to the millimeter.

    Counting the Forest for the Trees

    Integration of aerial and ground-based mobile mapping sensors and systems is enabling a team of Purdue digital forestry researchers to locate, count and measure more than a thousand trees in a matter of hours. “The quick, accurate inventory of the global forest ecosystem will improve our ability to prevent forest fires, detect disease, perform accurate carbon counting and make informed forest management decisions,” said Songlin Fei, the Dean’s Remote Sensing Chair. The Purdue-made systems integrate GNSS and inertial navigation devices with lidar and cameras, deployed with manned aircraft, drones and backpack-mounted systems. The technology gathers a variety of information about each tree, including height, trunk diameter and branching formation. The team maintains the precise location and time tags of all acquired features.

    SMARTWATCH REVEALS RUNNER’S FATE

    On the morning of July 10, Berkeley resident Philip Kreycik went for a run in Pleasanton, California. That day, temperatures reached 106 degrees, and he didn’t return home. His body was found Aug. 3, reports the San Francisco Chronicle. His Suunto smartwatch stopped tracking movement 4.5 hours after he started his run. GPS data from the watch showed him moving in erratic zigzags and circles before he stopped. Experts concluded he experienced delirium before succumbing to heat exhaustion.

    GANGS TARGET FARM DEVICES

    Organized gangs riding e-scooters are stealing high-value GPS/GNSS technology from farms in the United Kingdom, reports BBC News. Insurer NFU Mutual said the cost of replacing the stolen equipment nearly doubled in a year to £2.9 million. The technology, in worldwide demand, has become the “rural thieves’ top target,” the insurer said. GPS/GNSS equipment on tractors can cost up to £10,000 per unit.


    SPACE FORCE RECRUITS WITH GPS

    A 13-minute recruitment commercial from the U.S. Space Force debuted Aug. 24, with GPS as a star. “There’s no such thing as a day without space operations. You just don’t see them,” explains the video, mentioning how GPS is key to the operation of ATMs, cell phones, gas pumps, traffic lights, power grids, guided missiles and more. The commercial states that the Space Force is seeking guardians who will help protect satellites from attack and debris. Current guardians describe the importance of GPS. “We won’t just think outside the box, we’ll think outside the atmosphere, in one of the most challenging environments ever known,” concludes the video. “The sky is not the limit.”


    THIEVES STEAL TRACKERS AND… (GUESS THE REST)

    Two burglars who stole a package from a drop-off box were quickly apprehended — the package was filled with Roambee GPS-based trackers heading to a COVID-19 vaccine maker for use in tracking shipments. The Santa Clara Police Department was ecstatic to learn what the thieves had stolen, reports Roambee, who knew the package had gone missing. Unaware of what was in their trunk, the thieves traveled more than 761 miles around the Bay Area before being arrested 14 days later on July 18.

    COVID brings better measurements

    A new study shows that the quality of GNSS reflectometry measurements may have improved significantly during the pandemic because of the lack of cars parked near the ground station. The study, carried out by geodesists from the University of Bonn, investigated the location of a precise GNSS antenna in Boston, Massachusetts, where parked cars near the ground station decreased accuracy from 2 to 4 centimeters. GNSS reflectometry is used for earthquake early warning systems, determining flood risks, and many other geodesy applications. Read more about the study.

    But can you press the right button?

    A Riegl long-range terrestrial laser scanner helped field test the newly designed MS1 Mars Analog Spacesuit. The test simulated how the new spacesuit design would perform in a polar, Mars-like environment ‚ in this case atop the Grimsvötn Volcano on the Vatnajokull Glacier in Iceland. The field test was part of a research expedition conducted by the Iceland Space Agency. The team included NASA Coordinator and Rhode Island School of Design (RISD) Professor Michael Lye, who led the team that designed the MS1, and doctoral students from the University of Iceland.

    Squid scandal

    In June, a fleet of 300 Chinese fishing vessels entered the waters of the Galápagos Islands, reports environmental news website Mongabay. The ships had ostensibly turned off their GNSS-based automatic identification system (AIS) transponders to engage in illegal activities. Their presence was detected by their overhead lights and industrial jigging machines to attract and catch squid. An analysis of radio-signal data also detected unidentified ships within Ecuador’s Galápagos exclusive economic zone (EEZ).vThe new data provide additional, but still inconclusive, evidence that the Chinese fleet may have entered Ecuador’s EEZ.

    Bike-sharing chaos

    A pilot program in Shenzhen will use China’s BeiDou to regulate bike-sharing and address the problem of bikes parked chaotically or in unpermitted areas, according to Chinese news service Caixin. The program is part of Beijing’s push for wider adoption and commercialization of BeiDou. With guidance from the city’s transportation bureau, BeiDou modules on shared bikes will display parking spots. Users will have to park them within geofenced parking spots.

    Use that app in Germany? No Waze!

    The German government has amended its road traffic regulations to outlaw apps that alert drivers to speed cameras. The law makes it clear that any app used for traffic-monitoring alerts is forbidden, whether it runs on a phone, tablet or a GPS navigation system. Violating the traffic laws and using speed camera apps inside a car could result in a fine of up to €75 (about $83). Both Garmin and TomTom have emailed registered users alerting them to the news.

    Making the most of GPS data

    University of Nevada 2020 Outstanding Researcher Geoffrey Blewitt has made the most of GPS data to study changes in Earth’s crust, from the Ice Age to today. Nevada Today outlines his significant discoveries, including that GPS data may hold a key to detecting dark matter. Other discoveries: Nevada is the fastest growing state, geologically speaking, as it spreads apart. Drought in the western U.S. is causing the Sierra Nevada to lift, and the melting of ice sheets in Greenland is changing the shape of Earth.

    Koala care

    Drones equipped with FLIR thermal-imaging cameras helped save koalas injured in this summer’s Australia bushfires. In a search-and-rescue operation, Victoria wildlife experts and police used DJI Mavic 2 Enterprise Dual drones to scan the forest for injured koalas, many found clinging to scorched eucalyptus trees. The images were relayed to a ground station in a nearby van for closer inspection. When a koala was located, the experts stepped in to assess the animal, and if needed, provide healthcare and relocate it. The team used cherry pickers to retrieve the little animals.

    Chinese surveyors take BeiDou to the top

    On May 6, more than 30 Chinese surveyors left base camp to summit Mount Qomolangma — known in the west as Mount Everest. The team is using both traditional and modern surveying and mapping technologies, and China’s BeiDou Navigation Satellite System (BDS) will be applied to the elevation survey for the first time. The previous survey in 2005 used GPS to measure the height (found to be 8,844.43 meters); this year’s survey uses all four GNSS, with BDS data as the main reference.

    Quantum entanglement

    In a paper published April 20 in Physical Review Letters, University of Arizona engineering and optical sciences researchers, in collaboration with engineers from General Dynamics Mission Systems, demonstrate how a combination of two techniques — radio frequency photonics sensing and quantum metrology — can give sensor networks a previously unheard-of level of precision. The work involves transferring information from electrons to photons, then using quantum entanglement to increase the photons’ sensing capabilities. The quantum-sensing paradigm could create opportunities to improve GPS receivers, astronomy laboratories and biomedical imaging capabilities, as well as improve the performance of any application that requires a network of sensors.

    Earthquake reversal

    Researchers evaluating movement of GNSS ground stations have discovered large-scale, back-and-forth ground movement preceding the 2010 seaquake off of Chile and the 2011 Tohoku-oki seaquake off of Japan. Researchers from the Geoforschungszentrum Potsdam (GFZ) with collaborators from Chile and the United States say both quakes showed multiple strange reversals of ground motion — an extremely slow “wobbling” of the continental plate — over a period of five months (for Japan) and seven months (for Chile). The discovery was made possible by the amount of data collected by the GNSS stations in both countries.

    1. A new use for GNSS satellites

    University of Padua researchers say GNSS satellites make possible global quantum communication, beaming information between a satellite and an Earth-based ground station. They exchanged a single photon over 20,000 kilometers to prove secure quantum communications can be implemented on a global scale using GNSS. Results show the first exchange of a few photons per pulse between two GLONASS satellites, using the passive retro-reflectors mounted on the satellites, and the Space Geodesy Centre of the Italian Space Agency. The results could provide solutions for GNSS security for satellite-to-ground and inter-satellite links by using quantum information protocols for quantum key distribution.

    1. When horses answer the call

    Taking a ride in a horse-drawn carriage delights many visitors to historic Charleston, South Carolina. Until now, city crews cleaning up the presents horses leave behind have relied on flag indicators left by carriage operators. Now the city is testing a new method. Carriage operators will send the exact location to equine sanitation crews using small GPS-enabled devices. When a horse or mule takes an on-street nature break, the guide presses a button, and the equine sanitation crew is notified of exactly where to go. When the cleanup is complete, the notification is deleted.


    2. Detecting rain over the ocean

    Despite a wide variety of monitored geophysical parameters, GNSS signals reflected off the Earth’s surface (GNSS reflectometry) have never been used to obtain rain information. A new study presents evidence that data from the U.K.’s TechDemoSat-1 potentially enables the GNSS-R technique to detect precipitation over oceans at low winds. The study — by scientists at the GFZ German Research Center for Geosciences at Potsdam — could serve as a starting point for developing a new GNSS reflectometry application, which might also be implemented for low-cost GNSS remote-sensing missions.

    4. Guinness decision pending on world’s steepest street

    Dunedin, New Zealand, claims to have the world’s steepest street (Baldwin), a title officially challenged in January by the town of Harlech, Wales, when residents walked up and down the narrow, winding Ffordd Pen Llech carrying a GNSS surveying receiver. A total of 14 data points were recorded on the 330-meter-long road, which had an altitude accuracy of ±5 centimeters. New Zealand surveyor Richard Hemi said the GNSS method used by the Welsh group might not be accurate. Best accuracy is to survey from the center of the road — easy on Baldwin St. but much more difficult on a winding lane. The survey was sent to Guinness World Records, which will issue a decision this spring.

    A handheld GPS device uses touch to help you determine where to walk. Made with a 3D printer, the cube-shaped “Animotus” was designed with the visually impaired in mind, reports YaleNews.

    Designed by Adam Spiers, a Yale University post-doctoral associate in mechanical engineering, the Animotus is designed in layers, with the receiver in the middle. The top layer revolves to show what direction to walk, extending to indicate distance.

    When it stops twisting and returns to its cube shape, you’ve reached your destination. It can be programmed wirelessly on a computer or a smartphone.

    Spiers said he chose touch for guidance over sound because of the many aural distractions.

    (Diagram: Yale News)

    The Animotus was tested in London in an immersive production of a play based on the novella Flatland, about a two-dimensional world. Using the Animotus, the audience was guided through the church to uncover the plot. When the Animotus signaled participants to stop, narrative and sound effects took over. The performing company includes sight-impaired members.

    The Animotus was demonstrated at the World Haptics Conference in June at Northwestern University and received “quite a bit” of interest, Spiers said.
