Advances in GNSS technology constantly expand the range of projects that benefit from them.

ComNav Technology

A telecom company adopted its CORS station to build China’s national CORS service for public companies. It is increasingly used for field robotics, including the development of self-driving cars.

Leica Geosystems

Bernhard Richter, vice president of Geomatics, Leica Geosystems AG, pointed to one of the biggest infrastructure projects in Europe, which aims to connect London to Birmingham, Manchester and Leeds with a high-speed railway system, avoiding the need to fly between those cities. This will have great environmental benefits because high-speed trains are much more efficient than planes.

However, high-speed rail requires tremendous precision. “First comes the prep work, moving dirt,” said Richter. “Then you must install the railroad ties with tenths of a millimeter precision relative to each other to avoid side accelerations. For a surveyor, it really has everything in one project. You need to constantly work with civil engineers. You then try to build as much as possible with machine-control-guided systems to make the leveling as automated as possible.” The project will include building bridges over whole valleys and monitoring them, particularly during the construction phase, to ensure that they are not moving.

“Even the factory they are building is huge, so just to build the factory you need a lot of surveying,” Richter said. The project is generating 25,000 jobs at 300 construction sites, all of which must be managed on very tight schedules. In this context, the quality of the survey gear is critical. “On a construction site, the surveyor should be an invisible person,” Richter said. “When they come with the big machines and want to get stuff done, they don’t want a surveyor on the site. So, he has to work off hours, then remain on alert and trust that what comes out of an instrument is correct.” Leica Geosystems is one of the main suppliers for this project. “They chose us because of our focus on reliability, trust and quality.”

Trimble

Software is increasingly driving sales, pointed out Boris Skopljak, vice president, Surveying & Mapping Strategy and Product Marketing at Trimble Inc. As an example, he cited Trimble’s SX12 scanning total station, which uses Trimble Access software to leverage scanning, imaging and traditional total station capabilities in the field. “We have provided more inspection tools to enable people to decide whether something is meeting the tolerance.” The Trimble Connect cloud-based collaboration platform, coupled with the continuous field and office connectivity, has driven productivity increases and moved customers toward choosing the company’s solutions, he said.

As an example of Trimble solutions, Skopljak cited City Rail Link, New Zealand’s first underground rail network and the largest transportation infrastructure project ever undertaken there. “The Trimble R10 was integral to acquiring static observations above the work site, while the Trimble S9, DiNi and Trimble Business Center network adjustment were game changers for the survey control network,” he said. To expedite mine tunneling the surveyors used the SX12’s combined total station and scanning functionality with Trimble Access field software infield inspection tools. “Fewer customers are choosing solutions on a spec. It’s not about how many satellites you can track, for how many days, or how many points you can scan. They are choosing solutions based on the ecosystem and productivity.”

It can be easy to take GPS for granted as the average driver and smartphone user continues to enjoy convenience, entertainment and navigation from this technology, enhancing nearly every part of our daily lives. While we may not enjoy its benefits every day, one important use case keeps us and our environment safer: GPS has become a vital part of modern emergency response.

Many Americans across the nation are preparing for the impending hurricane season or the threat of other natural disasters, such as wildfires and earthquakes. GPS will play a critical role in recovery and response efforts. When natural disasters occur, accurate and actionable location information helps save lives and restore critical infrastructure as quickly as possible.

GPS has fundamentally improved access to information that can help the public prepare for these natural disasters, rather than waiting for them to strike. This information is more critical than ever. For example, California’s Oak fire spread to almost 20,000 acres and is part of a larger trend in California that has destroyed 14,700 buildings and killed 36 people over the past two years. Farther north, 530 wildfires in Alaska burned areas larger than the state of Connecticut in the state’s worst fire season in recent history.

In addition to helping the public face natural disasters, GPS helps firefighters plan their operations more efficiently and enables them to receive real-time information on the location of the wildfires they are fighting. With real-time mapping, planning and operations, fire chiefs can respond immediately to areas where wildfires are dangerously advancing.

In turn, GPS protects our first responders by preventing firefighters from getting caught in unpredictable fires they would have otherwise not known were heading their way.

Firefighters use IGNIS drones to help prevent wildfires from starting or safely contain them with backburns. IGNIS relies on GPS for tracking, safety and control, which in turn helps firefighters avoid the dangers associated with being near prescribed burns. Without GPS, resources to help firefighters would not be deployed as efficiently — wildfires could spread even more quickly as a result, causing even more damage to our homes and infrastructure.

Beyond wildfires, GPS technology is critical to emergency response and weather safety. GPS data allow emergency responders to better locate callers and reduce the incidence of misrouting to outside jurisdictions. Using GPS data, a caller can be located in close proximity to his or her actual location. By reducing rates of misrouting and accurately pinpointing emergency locations, GPS helps reduce response time by taking away the need to reroute calls and search for callers’ locations.

In a recent experiment, NASA-commissioned researchers used GPS signals to better predict a hurricane’s maximum wind speed, which could help federal agencies and forecasters better predict the danger of hurricanes and provide more actionable information to determine whether to issue evacuation orders.

The GPS Innovation Alliance (GPSIA) is proud to support the role of GPS as a critical enabling technology for public safety, disaster response and relief efforts. With GPS, precise real-time location information is at the fingertips of both consumers and first responders from pre-disaster planning efforts to post-disaster recovery. While GPS has already fundamentally improved modern emergency response systems, GPSIA will continue to advocate for the continued growth of these lifesaving GPS-enabled technologies and applications through rigorously developed technical rules, interference protections, and a predictable spectrum environment.

Many of us have grown accustomed to the ease of GPS-enabled technologies, from smartphone to fitness trackers. At GPSIA, we’re also particularly proud of the role GPS plays in the many other life-saving ways the technology is being used and are committed to continuing this critical work.

The Hawaiian Volcano Observatory (HVO) of the U.S. Geological Survey has been working to rebuild its geodesic monitoring network after lava consumed several GNSS stations in 2018.

The work began following the 2018 Kīlauea lower East Rift Zone eruption and summit collapse, with funding from the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157).

Teams are rebuilding and improving HVO’s geodetic monitoring network to better detect, assess and respond to volcanic hazards related to Hawaiian volcanoes. The main geodetic datasets used by HVO scientists to measure surface deformation (ground movements) are GNSS, tilt and satellite radar (InSAR) imagery.

HVO’s geodetic network includes more than 70 GNSS stations and 15 tiltmeters on the Island of Hawai’i that continuously record and transmit data. These instruments require routine maintenance, must be upgraded periodically due to age, and must be replaced if destroyed by volcanic activity such as in 2018.

Network upgrades include replacing out-of-date instruments and improving HVO’s network of near real-time monitoring instruments at critical areas on Kīlauea’s summit and rift zones to support early detection of magma movement and associated hazards.

Lava takes out stations

In 2018, lava flows destroyed three GNSS stations in the lower East Rift Zone. Another three GNSS stations were destroyed in the caldera collapses at Kīlauea’s summit.

HVO staff rapidly deployed new GNSS stations at nearby locations to allow for continued monitoring during the eruption. These rapidly deployed sites included GNSS smart antennas mounted on surveys tripods — a setup typically only used for temporary deployments of several days to weeks.

Many of these rapidly deployed sites were decommissioned and removed after 2018. However, 13 of them are still being used for critical monitoring and remain on temporary tripods. These sites will be upgraded and hardened using engineered fixed monuments and masts. New sites will also be installed to replace sites destroyed in 2018.

Emergency monitoring ongoing

GNSS receivers acquired by supplemental funds already have supported emergency monitoring of active eruptions and other volcano-related activity. Data from these instruments help HVO detect volcanic activity and inform partners at Hawai’i Volcanoes National Park (HAVO), Hawai’i County Civil Defense (HCCD) and Hawai’i Emergency Management Agency (HI EMA).

For example, HVO rapidly deployed three new semi-continuous GNSS stations in response to the December 2020 Kīlauea eruption. These stations gave scientists a more complete view of magma returning to Kīlauea’s summit.

Similarly, HVO deployed rapid-response GNSS equipment at two pre-existing benchmarks during the Kīlauea south caldera intrusion event in August 2021, allowing scientists to track the migration of magma from the south caldera to farther south. New instruments give HVO a more detailed understanding of and ability to monitor Kīlauea’s volcanic processes.

HVO’s geodesy program plays a critical role in monitoring Hawaiian volcanoes. HVO’s updated geodetic network ensures that scientists can monitor changes in the shape of volcanoes, respond to eruptions, and understand magma storage and movement underground.

“Thanks to supplemental funding, HVO is in the best position ever to leverage our state-of-the-art geodetic network to gain insights into the active volcanoes in Hawai’i, assess their hazards, issue warnings] and advance scientific understanding to reduce the impacts of volcanic eruptions,” stated Volcano Watch, HVO’s weekly newsletter.

Unicore has released its new generation of GNSS positioning product, the UM982. The UM982 is a high-precision dual-antenna real-time kinematic (RTK) positioning and heading module supporting all constellations and all frequencies.

The UM982 is suitable for use in UAV, precision agriculture and autonomous machine applications. The module is designed to meet the requirements of  these markets, providing technological innovation. The module supports BDS B1I/B2I/B3I, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, QZSS L1/L2/L5 and SBAS in dual-antenna mode. It offers the following advantages.

Small size. The UM982 is highly integrated. With its size of 16.0 × 21.0 × 2.6 mm, it is a compact dual-antenna heading modules that reduces the design area of the customer’s board by 72% compared to previous modules.

Low power consumption. Low power consumption means less energy usage and a better application experience. Lowering the power consumption while keeping performance high is one of the key technical research directions of the GNSS positioning modules. The average power consumption of all versions of the UM982 module is less than 0.6 W, which is suitable for applications that require low power consumption, such as UAVs.

High integration. The UM982 was developed on the basis of NebulasIV, Unicore’s proprietary GNSS system on chip (SoC). NebulasIV integrates RF, baseband and high-precision algorithms on a single chip, with built-in functions providing powerful support for the UM982’s high performance.

High precision and high performance. The GNSS SoC is a key part of the navigation system, and the performance of the chip largely determines the performance of positioning modules. High-level performance indicators include raw observation accuracy, RTK positioning accuracy, PPP positioning accuracy, and time to first fix.

Robustness. Using the company’s dual-RTK technology, the UM982’s two antennas can independently participate in deriving an RTK solution and outputting the positioning results. This is convenient for customers conducting reliable verification in various application scenarios. By checking the RTK positioning results of both antennas, abnormal measurements in complex scenarios can be avoided.

High reliability. A built-in, advanced anti-jamming unit provides the UM982 with strong anti-jamming ability. The module detects jamming and can output the jamming strength. It also supports digital encryption to ensure the security of data transmission, and supports multi-frequency independent acquisition and tracking to ensure the reliability and accuracy of positioning results even in complex electromagnetic environments.

NextNav is partnering with CentralSquare Technologies, a public-sector technology company, to integrate z-axis vertical location capabilities into its computer-aided dispatch products and mobile suite of public safety software solutions.

CentralSquare works with more than 75% of public safety agencies nationwide, including first responders, law enforcement, fire departments, emergency medical services and local governments, equipping them with real-time data and situational awareness to decrease emergency response times.

By tapping into NextNav’s Pinnacle network, CentralSquare will be able to provide public safety agencies with critical vertical location data needed to precisely pinpoint the location of civilians in need of assistance during an emergency.

The integration of Pinnacle into CentralSquare’s product suite will provide users with enhanced knowledge of the most efficient routes within multi-story buildings to further reduce response times.

“Together with NextNav, we’re helping public safety agencies meet the needs of today’s dynamic world, particularly in densely populated urban cities,” said David Zolet, CEO of CentralSquare. “Adding z-axis enables our systems to not only derive location (x-axis and y-axis) but height (z-axis). This capability is the next logical step, decreasing emergency response times and ultimately helping to protect our communities and those that serve them.”

CentralSquare’s partnership with NextNav further establishes the company as the market leader in public safety dispatch solutions with the addition of floor-level accurate z-axis location. Once deployed, CentralSquare will deliver z-axis visualization in a 3D view, bringing visualization to their agencies and clients’ first responders.

As part of a strategic alliance, Trimble and CLAAS have developed a next-generation system for CLAAS tractors, combines and forage harvesters.

The precision farming system includes the new CLAAS CEMIS 1200 “smart” display, GPS PILOT steering system and the SAT 900 GNSS receiver.

The CEMIS display uses Trimble’s new embedded modular software architecture for positioning, steering and ISOBUS technology for a seamless connection to control and monitor implements in the field. ISOBUS is an international communication protocol that sets the standard for agriculture electronics.

Trimble’s new architecture accelerates the development of a customized precision agriculture system by linking CLAAS’ machine interface and Trimble’s guidance capabilities into one common in-cab user experience.

“We understand the operators’ complexities of using separate displays with different user interfaces in the cab running the machine and performing precision farming tasks,” said Jim Chambers, vice president of Trimble Agriculture. “Working in tandem with CLAAS, we have jointly developed a next-generation precision farming system designed around one common user interface to provide CLAAS operators the best customer experience.”

“As an experienced, innovative and global provider of precision agriculture solutions, Trimble was our first choice as a technology partner,” said Carsten Hoff, managing director, CLAAS E-Systems. “Precision farming systems from Trimble have been field proven worldwide over the course of two decades. In addition, Trimble, supported by its subsidiary Müller-Elektronik, brings outstanding expertise in ISOBUS technology, which allows a display to control the machine and implement.”

The CEMIS 1200 display connects with the GPS PILOT system and SAT 900 GNSS receiver, based on the Trimble NAV-900 guidance controller, for positioning and steering capabilities. This solution provides sub-meter repeatable accuracy suitable for tillage, broad-acre seeding, spraying and harvest operations.

For even greater accuracy, users can subscribe to CLAAS-branded correction services from Trimble, called SATCOR, to achieve up to 2.5 centimeter pass-to-pass accuracy without a base station.

The precision farming system is already available for CLAAS TRION and is now expanding into LEXION, ARION, AXION and JAGUAR.

The U.S. Department of Transportation’s Federal Aviation Administration (FAA) has awarded $2.7 million to support research on how drones can assist in disaster preparedness and in emergencies.

“Every second counts in an emergency, and this funding will allow drones to safely and more quickly deploy in moments when minutes matter,” said Acting FAA Administrator Billy Nolen.

The research will explore the use of drones in providing effective and efficient responses to different natural and human-made disasters. It will address coordination procedures among drone operators from federal agencies as well as state and local disaster preparedness and emergency response organizations. The five universities and their award amounts are:

• University of Vermont: $1,195,000
• University of Alabama Huntsville: $828,070
• New Mexico State University: $400,000
• North Carolina State University: $200,000
• Kansas State University: $145,000

Today’s announcement is the third round of Alliance for System Safety of UAS through Research Excellence (ASSURE) grants, which brings the total to 20 grants valued at $21 million for Fiscal Year 2022.

The ASSURE Center of Excellence is one of six the agency has established to help advance technology and educate the next generation of aviation professionals. Research conducted through ASSURE is focused on helping the drone community safely grow and integrate into the nation’s airspace.

Earlier in 2022, Transportation Secretary Pete Buttigieg outlined six key Innovation Principles the department will apply when fostering transportation technologies. While continuing to commit to the highest standards of safety across technologies, these awards demonstrate the department’s commitment to exploring ways to leverage innovation to help communities and public-sector partners through experimentation.

More than 850,000 recreational and commercial drones are in the active drone fleet, and that number is expected to grow.
