Javad GNSS announces that, after a short retirement, Tom Hunter has rejoined the company as chief sales officer. Hunter will draw on more than three decades of GNSS industry experience, most recently with Javad GNSS and previously with Ashtech/Magellan as vice president.
“Tom is key to our operations,” said Nedda Ashjaee, CEO. “I am looking forward to reigniting this group of companies and continuing our four-decade tradition of bold innovation. Who better to do this with than the person who helped my father build the original company in the first place?”
Hunter will oversee sales channel development in support of a new market-driven roadmap developed by the executive team at Javad GNSS, also known as J-CORE.
Hunter’s association with Javad began in 1987 as one of the original seven people at Ashtech, Ashjaee’s namesake firm created shortly after his departure from Trimble Navigation. The firm brought numerous surveying industry firsts and other legendary products to market.
Company founder Javad Ashjaee passed unexpectedly in May 2020, leaving behind 200 loyal employees in offices around the globe. A strategic thinker, Ashjaee was known for operating “several steps ahead,” said one employee, having groomed his executive office and other support staff for a swift takeover in the event he were unavailable. Javad’s daughter Nedda, familiar to all who had conducted business with the firm, has spent the last 12 months carefully restructuring the business plan.
On March 31, Nedda Ashjaee, Tom Hunter and the rest of the J-CORE team hosted a two-day virtual gathering of global Javad GNSS dealers, technicians and other personnel, taking time to unveil the firm’s new strategic vision. The information and overall strategy was met with an overwhelmingly positive response.
Javad GNSS retains significant patent holdings relating to survey and mapping and offers what many of its customers believe to be one-of-a-kind system(s).
Hunter explained, “If you’re a surveyor or other positioning professional working with GNSS, you owe a debt of gratitude to Javad — the man dedicated his life to developing GNSS for the high-precision marketplace. You can see his hand in nearly every major GNSS survey system on the market today.”
“As we continue to develop and introduce new products in support of the surveying and reference station markets, we will use our exceptional technology and our U.S.-based world-class manufacturing facility to focus on new OEM applications and opportunities including strategic partnerships and private labeling,” Hunter said.
Unmanned aerial vehicles (UAVs) are something of a Swiss Army knife for the surveying and mapping communities. Commercial applications continue to grow, with UAVS — known as drones in the vernacular — gathering data and observations for agriculture, mining, utility inspections, natural resources, historical preservation, security, and many more applications.
UAVs perform high-risk tasks that keep workers out of harm’s way. They fly in places and situations difficult or impossible for aircraft to reach. They collect high-resolution imagery across the spectrum, accompanied by exact positioning and location data. They detect and help preserve the past in rich detail.
A study by Polaris Market Research predicts the UAV market will reach $15.62 billion By 2026, spurred not only by new use cases, but through miniaturization and improvement of components. Payload components that continue to improve include GNSS receivers, inertial measurement units, micro-electromechanical components, cameras of all types (RGB, thermal, hyperspectral and high-resolution video) and lidar. (For more on lidar with UAVs, see Diving into UAV lidar surveys.)
In these pages, we share a variety of case studies from companies taking part in the UAV revolution. In many of these use cases, companies saved considerable money using UAVs rather than more traditional surveying methods. In others, UAVs are helping to keep people safe.
In all cases, using UAVs provides a wealth of data that offer new insights, no matter the application.
Aceinna and Point One Navigation launch hardware and software platform for precise positioning in agriculture, construction, mapping, surveying, robotics and trucking
The OpenARC positioning service is now commercially available. OpenARC is a precise-positioning hardware and software platform for system integration of GNSS corrections with high-performance inertial navigation system (INS) and real-time kinematic (RTK) hardware.
OpenARC is offered by Aceinna, a developer of inertial-based guidance and navigation systems, and powered by Point One Navigation.
With an RTK positioning engine and GNSS corrections delivered from a ground-based network of secure base stations, OpenARC will reliably improve position accuracy for autonomous vehicles to centimeter-level accuracy. The platform combines Point One’s Polaris GNSS correction service with Aceinna’s OpenRTK330 hardware and software solution for developers of autonomous systems in trucking, precision agriculture, construction, mapping, surveying and robotics.
OpenARC provides high-precision positioning and localization applications, enabling centimeter-level accuracy for challenging tasks such as lane keeping, precision agricultural guidance, and UAV landing maneuvers.
OpenARC is integrated into the OpenRTK330LI navigation module to provide a secure, vertically integrated and easy-to-use positioning platform. OpenARC is very scalable, supporting single-unit installations and high-volume deployments.
Point One’s proprietary Polaris GNSS cloud correction service delivers superior station density in areas where operators need it the most, including urban centers and suburban surrounding areas, enabling cold convergence times of under 10 seconds.
Polaris provides continuous position monitoring and tracks all modern satellite constellations. Its base-station technology includes advanced anti-jam, interference mitigation, security and integrity monitoring. Its architecture allows for GNSS corrections in RTK or state space representation (SSR) configuration. Its open-source interfaces are compatible with multiple receivers and chipsets, and the service is compatible with any NTRIP/RTCM3 compliant receiver.
Mapping company ProStar Holdings Inc. and survey device company Bad Elf have partnered to produce a solution designed to gather the precise location of surface and subsurface utility data.
PointMan combined with Bad Elf is designed to quickly and precisely, locate, identify and display critical surface and subsurface utility data.
Bad Elf’s survey-grade GPS/GNSS receiver combined with ProStar’s flagship mobile-mapping solution, PointMan, now provides a powerful and user friendly solution for any industry requiring precision mapping including subsurface utility engineering (SUE) and utility locating professionals.
“The Bad Elf Flex was quickly configured by ProStar and performed flawlessly with the PointMan app. We found that consistent high accuracy was easy to maintain while collecting data,” said Larry Fox, vice president of marketing and business development at Bad Elf. “The depth of collection tools and export facilities exceeded our expectations. Given the seamless integration with Bad Elf Flex, PointMan demonstrated it’s a top-tier app for utility management, and expands our ability to provide best in class solutions to our users worldwide.”
“Equipment manufacturers like Bad Elf and their distribution networks are an important component of our sales and marketing strategy,” said Page Tucker, CEO and founder of ProStar. “Our goal is to continue to work with leading equipment manufacturers around the world to provide the most comprehensive, modern, and low-cost data collection solutions.”
ProStar’s flagship product, PointMan, is natively cloud and mobile, offered as a Software as a Solution (SaaS). ProStar’s solutions are being adopted by some of the largest entities in North America, including Fortune 500 construction firms, the largest subsurface utilities engineering (SUE) firms, and government agencies.
ProStar’s strategic partnerships are with geospatial technology and data-collection equipment manufactures and their dealer networks, including Trimble, Juniper Systems, Vivax-Metrotech, Radiodetection, Bad Elf and Subsite Electronics.

A new, twin cable-stayed bridge was built a few yards north of the original bridge by Tappan Zee Constructors LLC (TZC), a consortium of firms. The Left Coast Lifter — a huge crane on a barge previously used to replace a span of the San Francisco-Oakland Bay Bridge — was used to install groups of pre-assembled girders one full span at a time. Construction of the new bridge and demolition of the old one overlapped, with the entire project completed in May 2019.
The project was huge, complex and on an accelerated schedule. “Challenges included the size of the bridge, the river’s current, tidal variations, the water’s turbidity and strong winds,” recalled Jonathan White, product manager for Trimble Civil Construction Field Solutions, Marine. Conditions were particularly challenging for bathymetric data collection before and during the project. “The low visibility in the water made it a prime situation for sonar technology to play a major role.”
A licensed surveyor conducted a pre-dredge bathymetric survey, which was loaded into the construction software as a baseline. Trimble hardware, software and technical advice supported the demolition of the old bridge.
“As they were beating down the bridge with the jack hammers and trying to pick up the rubble from the river with the cranes, the main challenge was to keep the 11 machines that they had updated in real time with the most accurate 3D data, so that they could keep working,” explained Nathan Keys, a geospatial engineer at Measutronics, a Trimble dealership and project lead for the Tappan Zee Bridge project.
Rather than mount a sonar to the front of each construction barge, they used a single survey vessel to serve the machines (eight excavators and three clamshell cranes) with real-time data, using networked connections to update one machine at a time.
Whenever a crane operator thought he was done in an area — the machine guidance display in his cab told him that he had achieved the design depth — the survey boat would verify that, and either give the operator the go-ahead to continue working or point out any spots that were still too high or too low. “That way, they would avoid having to return to an area, which costs time and money,” Keys said.
Trimble equipment provided the positioning of the machines, tracked their motions, and visualized them, enabling the operators to “see” underwater where their bucket, grapple tool, clamshell, or other tool was operating. Trimble supported its dealer and the consortium that was executing the project, White said. “Measutronics is very well versed in the capabilities of Trimble equipment and, more broadly, marine construction workflows generally. If a piece of their equipment went down, we could swap something out and provide them with any support that they needed, and expedite that support because we knew how crucial it was with them being in the field pretty much 24/7.”
Marine excavation. The survey vessel was equipped with a Teledyne RESON T-20 multibeam sonar and a Trimble Applanix POS MV WaveMaster for motion and position. “The eight excavators were equipped with a Trimble marine excavator guidance package, which includes a GPS receiver and angle sensors working together to give guidance to the tool, whether it is a jack hammer, a bucket or whatever,” said Keys. “They also had three clamshell cranes with rotational encoders on the wire-out drums, to keep track of the bucket’s vertical. The central piece to all this is the Trimble Marine Construction software, which takes in the data from all the sensors, including the sonar, in real time and updates the display in the cabin.”
To install its sensors on machines, Trimble provides flexible aftermarket kits that come with weld plates. “We just point out to the customer where to weld the plates, then we will put the sensors on, run the cables to the cab, and do all the wire runs,” Keys explains. “It does not matter whether it is a Caterpillar or a Kobelco or whatever. They are aftermarket systems, so they can go on pretty much any machine.”
This project, Keys clarified, involved only machine guidance, not automation. “We were not using any of the machines’ own sensors. We showed them where they were and then the operator would have to control it.”
Trimble provided precise position and heading, White said. “Through a very accurate measure of where each of these sensors is installed relative to the phase center of the GPS antenna, we can determine how the machine is moving and measure that movement, so that we know exactly where the tool is relative to the position that we are getting from our satellite trilateration. It is not like the guy is sitting in the seat drinking a cup of coffee while the machine parallel parks itself. However, he is receiving a lot of information from all those sensors as to his tool’s position relative to that GPS location.”
Keys said the machines constantly log the data and their movements while they are running. “We can go back into those log files and pull out whatever we want,” he said. “On the survey side, when they do a scan or a survey of an area, that data is captured as a 3D point cloud of what the bottom looks like, which you can import into any software to visualize and quantify the riverbed and the rubble.
“The availability of that real-time sonar data kept those machines productive,” Keys said. “It keeps them from having to go back and do any kind of re-work.”
White said the technology is getting more affordable and user-friendly. “That is leading us, as a manufacturer, to look for ways to help further bring it into our standardized workflows. We have been working with Teledyne on those objectives.”
Trimble is also keen to advance the networking component, specifically to the marine sector, White added. “It is relatively new to marine construction projects. The ability to have a sonar vessel speaking to a machine, and all the machines to speak to each other, and to share a survey file is a very important objective for us.”
Every year, surveying associations worldwide celebrate Global Surveyor’s Day during the third week of March. This year is no different (even during a pandemic) and will be recognized on Tuesday, March 23.
While this past year has been full of challenges, the role of the surveyor on a global scale has continued to grow. As a professional land surveyor in the midwestern portion of the United States, my surveying experiences have been wide-ranging at times.
For those who know of me and/or have followed my writings here in GPS World, you probably understand how my perspective for the surveying profession has come to be. For those who have no clue about my background, let me give you a brief refresher:
Second-generation surveyor, born and raised in Central Illinois, United States
Surveyed in rural, suburban and urban environments
Began writing for GPS World in 2015 to share my surveying perspective
Even though my surveying career has spanned several decades, my experience has been limited to the areas described above. From my early days of spending hours in the county recorder’s office pouring through tract index books, all the way to viewing parcel shapes, scanned documents and high-resolution aerial imagery in today’s world, it seemed at face value that my experience covered most of the duties of the typical land surveyor.
My career has encountered robotic total stations, all iterations of GPS/GNSS data collection, laser scanning, and now UAV data collection. Throw in the development of the personal computer, COGO and CAD software, the Windows operating system, pen plotters, and countless software breakthroughs, and my perspective of the surveying profession had been front row for all the great things we now take for granted.
However, these advancements, in tandem with growing up in middle-class America, did not prepare me for a recent experience with a surveying/geospatial group new to me.
VCSP Wisdom Workshop
A virtual workshop was recently held to discuss the Volunteer Community Surveyor Program (VCSP) instituted in 2017 by the International Federation of Surveyors (FIG) and the FIG Young Surveyors Network (YSN). More than 125 attendees from worldwide locations logged into the sessions to learn about the program and how to become involved.
The program, titled “Sustainable Solutions for Land Based Community Problems: Tools and Modern Approaches,” spanned two days and two four-hour sessions. Before we jump into the specifics of the program, first we will offer another brief refresher on FIG and its YSN.
The Fédération Internationale des Géomètres, now known to English speaking nations as International Federation of Surveyors, was founded in July 1878. It has grown into a worldwide non-governmental organization representing more than 120 countries and their surveying/geomatics professions.
The National Society of Professional Surveyors (NSPS) is a member organization and participates at various levels throughout FIG.
The FIG Young Surveyors Network (FIG YSN) was initially established in 2006 as a working group, and upgraded in 2009 to network status due to its rapid growth. This group of young professionals and practitioners worldwide has worked with groups such as the United Nations, World Bank, National Society of Professional Surveyors (NSPS) and Council of European Geodetic Surveyors (CLGE) to promote the profession, increase opportunities for young professionals, and be an agent for social and climate change.
This YSN workshop set lofty goals, including providing information about the VCSP as well as informing participants of the current means and methods of surveying in underdeveloped countries. For context, here are the program topics covered over the two days:
DAY 1: Community problems, land tenure and tools for land management
Experiences and opportunities of humanitarian surveyors (past volunteer community surveys)
Land management, community development and open technologies
Identifying the relationship between land management and community development
The skills of a humanitarian surveyor
Introduction to STDM and Cadasta tools
An implementation of the STDM and Cadasta tools for land management
DAY 2: Building capacity and implementing modern land-management approaches
Leveraging land-management tools for problem solving and decision making
Designing country-scale solutions for land rights and tenure security issues
Gathering resources for land management projects
How much have land rights and tenure insecurity impacted your country?
Documenting and publishing experiences
What’s next? Parallel sessions by FIG region
Introduction to the humanitarian surveyor
Like most land surveyors in the United States, our role has been well-defined for generations. We establish and/or reestablish parcel boundaries (that is, original or retracement surveys). While our duties have expanded based upon technology, the central responsibility of the surveyor has been established as an expert measurer and provider of boundary information.
In the 200+ years since the westward expansion and formal establishment of most of the United States, the role of the surveyor has evolved into more of a commercial purpose. A surveyor’s principal responsibility is to protect the public, but that meaning has much different connotations in lesser developed countries.

In the recent past, surveying efforts in many developing countries have been like the early General Land Office surveyors in the 1800s. A surveyor in these regions is out in front of development of unclaimed lands, observing natural and manmade boundaries to guide the decision-making process in establishing parcel rights. The methods and procedures used to date in many lesser developed countries are much like 19th-century surveying — primitive instruments and crude maps sketch property claims with little to no authority.
Surveying: The Next Generation. Here is where the concept of the community or humanitarian surveyor comes into the picture. A new generation of surveyors is using modern technology not just to map existing boundaries and improvements, but also to collect additional data that will be analyzed to help improve living conditions. With the introduction of GNSS technology, establishment of parcel boundaries now takes an accurate and precise shape in GIS databases created for improving conditions in these areas.
Additional attributes are collected to determine utility needs, communication availability and access to medical care.
The easy solution seems to be that, as a larger part of the surveying community, we send teams of surveyors to these countries to locate and establish boundaries as well as perform site studies to determine living conditions and potential improvements. If it were just that easy…
Local government: Friend or foe?
Often, these surveyors are going into regions where the local or national governments do not agree with empowering their citizens with property rights and allowing them access to basic utilities. Part of the humanitarian surveyor’s role is to get to know the “lay of the land” when it comes to local order.
Many remote places are controlled by local gangs, tribes or other factions. These groups forbid the population around them to own their property. Even though it may seem like these physical parcel boundaries exist, most of these people do not have title or land tenure rights. This is partly because of the local control situation, but can also be due to the lack of sophistication within the local or national government.
Communication hurdles. Another hurdle for the humanitarian surveyor has nothing to do with their professional capability — it relies solely on appearance, body language and ability to bridge a communication gap. For example, most first-world nations rely strictly on communication skills and the competence to effectively work with other people. We often easily trust those who present evidence of competency with no previous interaction.
In third-world countries, however, locals do not trust outsiders and place competency on those who have built long-term relationships with them. They also rely heavily on body language and facial expressions to convey trust. Local citizens in these areas are less likely to trust visiting older generations who are not able to understand these visual cues.
Combining the factors of trust of the local citizens with the unsteadiness of government and/or lawlessness, the humanitarian surveyor must also be able to determine common property lines, locate lines of occupation, and remain neutral in providing guidance to adjacent neighbors. These conditions often include areas for crops and livestock, as well as places for food growth and development.
With little to no money and lack of commerce available, many of these regions are food poor. Locals are forced to harvest their own food, so having a plot of land to grow these crops is critical.

In more established areas, it can be challenging to determine land tenant rights with many shanties and lean-tos being joined structurally. It is equally difficult to determine if any common utilities exist in these areas, such as stormwater channels to help with rainfall.
Add to these improvement location duties the need for better census data to help with government analyzation of population to apply for aid from other countries.
The good thing is that technology has progressed in creating tools for geographically locating all these entities, including population, with a multitude of attributes to complete proper analyzation. But there is a catch.
Technology challenges worldwide
One of the biggest issue surveyors face when providing services in these areas is the lack of advanced technology and computers. These areas may not have reliable utilities, such as electricity or running water, much less viable internet or Wi-Fi. If computers do exist with local government, they are often years behind in computing power and software. Even operating systems like Windows are a rarity in many of these countries.
Networking accuracy needed. Most humanitarian surveyors will bring their own equipment and computers, so that problem can be averted. But what about geographical locations? Yes, GNSS constellations are available worldwide, but accuracy using just satellite signals is not sufficient for location of parcels and improvements.
To get survey-grade accuracy, the surveyor will typically utilize a correction service or base station on a known value. Most of these corrections are based on Continuously Operating Reference Stations (CORS) or similar established reference stations, so creating a georeferenced datum for the surveyed location takes time and knowledge. Once the network is established, lots of work and oversight is necessary to provide quality control on the data being located.

To add to these issues, most of the staff necessary to complete the surveys must be brought in due to the lack of education at the location. The role of the humanitarian surveyor will also be to teach the craft of surveying to locals, who will continue to expand the area cadaster after the volunteer surveyor has left.
Open-Source Software. However, affording the necessary equipment, computers and software to continue the newly established system is also a hurdle for the community. While the price of computer hardware has greatly reduced over time, the advancement of software and cost of upkeep provides a greater monetary challenge.
Enter open-source software, based upon Linux and other free computer operating systems. This software has been developed with these situations in mind. It allows for customization to each user’s specific need. There are several GIS and data-collection platforms to fit the needs of these budding communities and countries. Open-source and public-domain software allow even the most basic of cadaster needs to be completed efficiently.
Young surveyors network to the rescue
From a technology standpoint, it makes sense that the FIG Young Surveyors Network began this program to help underdeveloped nations begin to create simple cadasters for assessing their property and improvement needs. The younger generation has grown up with technology and can easily teach someone how to embrace it and trust the results.
This younger generation is also the developer of open-source software and tools and sees the value in providing low- to no-cost applications to those who need it most. While the hard part is collecting the data and working with the locals to establish common boundaries, count the population, and determine the utility needs, they take pride in being part of a solution for a segment of the world that may not have any other chance or choice.

One of the interesting portions of the workshop was the breaks between segments. While it was a time to step away from the computer/tablet/phone, the organizers broadcast videos of musical groups from around the world and encouraged the participants to stand up and dance, with their cameras on. While I did not partake in the dancing (it was 4 a.m. at my home), I applaud the Young Surveyors for providing a welcoming atmosphere where each person could be themselves. Several of the participants were in Africa and Asia on cellphones, so creating a workshop environment that worked for all levels of engagement was fascinating.
What I learned
My biggest takeaway was simply learning about the term “humanitarian surveyor.” My earlier reference trying to relate these volunteers to the GLO surveyors, while in the same vein in establishing land boundaries, misses badly in terms of overall contribution to the communities in which the volunteers visit.
The work they perform is truly humanitarian. While I have tried to comprehend the conditions they are facing, I again fall short in fully experiencing what the role has to offer.
One of the testimonials was regarding a group that went to Nepal following the 2015 earthquake to help re-establish towns and parcels. The pictures were stunning, and the memories shared were heartfelt. To be one of these volunteers is truly a humanitarian effort.
Well done, FIG Young Surveyors Network and the Volunteer Community Surveyor Program. I will do my best to not take life here for granted anymore.

The PGM utilizes STMicroelectronics’ TeseoV chipset in Quectel’s multi-constellation, dual-band LG69T-AP receiver to create an affordable, easy-to-use solution for customers building industrial, last-mile and internet of things (IoT) platforms. This solution operates with the highest accuracy when used with Swift’s Skylark positioning service.
CAST Navigation tested Emcore’s SDN500 inertial navigation system (INS) in an ultra-high-altitude flight simulation and achieved success. The test required simulating performance at an altitude of more than 24,000 meters and velocities over 600 m/s. Only a few aircraft in the world have such capabilities, including the SR-71 Blackbird, but it is not practical to participate in a test flight on the SR-71. Simulating the SDN500 INS test flight to specific customer profiles on a CAST system is straightforward and cost-effective. Emcore relies on GNSS/INS simulators for hardware-in-the-loop testing to verify the expected performance of algorithms. Emcore sought to validate the velocity and altitude limits of a new GNSS receiver along with the algorithm performance in a tactical-grade SDN500 system.

A highly optimized wind field produces droplets of the correct size and consistency. The T20 is also equipped with a new four-channel electromagnetic flow meter, which monitors and controls four hoses individually, ensuring an efficient flow rate for each nozzle.
A new virtual base station (VBS) feature is available in Qinertia, GNSS and inertial navigation system (INS) post-processing software. Trajectory and orientation are greatly improved by processing inertial data and raw GNSS observables in forward and backward directions. The VBS computes a virtual network around a project in which position accuracy is maximized, homogeneous and robust, such as a PPK short baseline. Once surveyors collect data, Qinertia chooses the most relevant reference stations, builds a virtual network and brings the project to centimeter-level accuracy with no convergence effects, even in urban areas.

The PD machine is fitted with Carlson sensors and a ruggedized Windows-based MC10 tablet. The entire system is then calibrated within PDGrade.
SkyTraq is offering a 12 x 16 millimeter multi-band real-time kinematic (RTK) receiver for centimeter-level accuracy positioning applications. The PX1122R works with all the four GNSS, using GPS L1/L2C, Galileo E1/E5b, GLONASS L1/L2 and Beidou B1I/B2I signals concurrently to maximize positioning availability even in difficult urban environments.
A single-chip system-on-chip, the PX1122R is designed to deliver reliable, centimeter-level accuracy positioning for autonomous unmanned ground or aerial vehicles, the internet of things, and traditional land surveying and precision farming applications.
The PX1122R has an RTK initialization time under 10 seconds and a maximum update rate of 10 Hz. Its update rate provides in-time positioning with a fast response time and improved guidance for fast-moving applications, the company said.
Moving-base RTK for GNSS precise heading is also supported. By using two PX1122R and two antennas with 1-meter separation, highly accurate 1-sigma heading accuracy of 0.13 degree can be obtained; such heading accuracy is immune to magnetic interference and unaffected by the receiver’s speed.
The PX1122R can serve as a key component to provide precise position and heading information for autonomous applications. PX1122R sample, data sheet and evaluation boards are available now.
Founded in 2005, SkyTraq Technology Inc. develops high-performance chipset and module solutions for the consumer market. Its initial product is L1-GPS-centric, and now its products cover L1, L2, L5, L6 band GPS/GLONASS /Beidou/Galileo/QZSS/NavIC/SBAS applications.
A shipping container with several pieces of key GNSS and survey instrumentation is bound for the East African country of Rwanda. The equipment, an in-kind donation from Topcon Positioning Group, will be used in support of Bridges to Prosperity (B2P), an organization committed to building trail bridges to improve the lives of people in rural areas worldwide.

According to B2P, almost a billion people around the world lack safe access to critical resources like healthcare, education, or employment due to an impassable river. Building safe, structurally sound trail bridges for people to travel by foot, bicycle, or motorcycle has an immediate, impactful effect on the lives of those in the area.
“We are fortunate that, even with challenges presented by the COVID-19 pandemic, we have been able to implement new safety measures with limited disruption to our building schedule,” said Devin Connell, B2P’s corporate program director. “Right now, our surveying efforts predominantly involve simple equipment such as auto levels and range finders, which can be time consuming when complex survey information is needed. The equipment from Topcon will increase our surveying capabilities, streamline the design process, and support us in building more trail bridges for isolated communities.”

In addition to the instruments — a pair of GNSS receivers, two total stations and data collectors — B2P will have access to the Topcon suite of software products, which will assist both the design process and the transfer of files from the field to their remote office or the engineering team working with them. According to Ron Oberlander, vice president of Topcon Global Professional Services group, however, the company’s role extends well past the equipment itself.
“We are excited to be a contributing part of this program,” he said. “But, in order for B2P to use these solutions to their fullest and increase their overall productivity, a training effort will be needed and we’re already setting plans in place for that to happen.
“In addition to conducting online virtual training sessions with B2P staff, we are making eLearning possible by allowing access to MyTopcon, our company knowledge portal. With these tools, they can gain familiarity with their receiver or total station or use the Topcon software to learn how to collect points — all without having us there. They want to be able to hit the ground running once the equipment arrives and this will help make that happen.”
Connell said that their improved survey capability will help accelerate the company’s bridge building. “We go out and survey a year in advance, looking at as many as 100 different remote sites and, tough as it might be, establish priorities with the local governments. We are looking forward to our continued growth in 2021 and, thanks to the generosity of companies like Topcon, that process will be a much better one.”
An IMU-RTK GNSS receiver that fits in your hand and a fully integrated GNSS base station add a new scale to GNSS surveying applications.
CHC Navigation (CHCNAV) has announced the immediate availability of the i73 GNSS, a versatile pocket-sized IMU-RTK GNSS rover with an integrated inertial module and the iBase GNSS, a rugged base GNSS receiver.
The combination of the i73 GNSS and the iBase GNSS offers a productive and affordable solution for measuring and staking out points in any surveying, mapping or construction application.
“Surveyors and construction professionals are forced to carry heavy and cumbersome GNSS receivers in most situations, resulting in unnecessary fatigue and lower productivity,” said Hans Huang, product manager of CHC Navigation’s Survey and Engineering Division. “Taking this into account, we have developed our pocket-sized i73 GNSS, the lightest GNSS rover powered by the latest IMU-RTK technology, and much more. Our iBase GNSS station follows the same concept of an all-in-one solution, making the need for external radio modems and other bulky accessories obsolete.”

The GNSS iBase is a fully integrated GNSS base station, specifically designed to meet 95% of surveyors’ needs when working in UHF GNSS base and rover mode. The performance of the iBase UHF base station compared to a conventional external UHF radio modem is virtually identical. But its unique design eliminates the need for a heavy external battery, bulky cables, an external radio, and a radio antenna. Its 5-watt radio module provides operational GNSS RTK coverage up to 8 km.
