New web tool exports ready-to-deploy XML files, enabling fast and centralized pre-configuration of Eos Tools Pro GNSS settings.
Eos Positioning Systems has released the Eos MDM Configurator, a web‑based tool that allows organizations to quickly create and deploy pre-configured Eos Tools Prosettings across large numbers of mobile devices via their third-party mobile device management (MDM) systems.
Until now, administrators who wanted to deploy Eos Tools Pro through their MDM needed to write an XML configuration file manually — a process that was time consuming and potentially error-prone. The Eos MDM Configurator eliminates manual coding entirely. The tool guides users step‑by‑step through five GNSS categories, supplies a preview of the XML code, and allows the user to export their XML file, compatible with any third‑party MDM solution.
With the Eos MDM Configurator, organizations can centralize control of Eos Tools Pro settings, standardize GNSS data quality, and save time by eliminating manual app configurations.
The five categories that can be pre-configured using the tool include differential corrections, altitude and geoid model, datum shifts, alarms and miscellaneous.
The Eos MDM Configurator is available at no cost to Eos GNSS receiver users. All that’s required to build a configuration is a desktop browser with Internet access. Deploying the resulting XML file requires a third‑party MDM solution, an Eos GNSS receiver (any model), Eos Tools Pro, and at least one mobile device running iOS or Android.
Researchers at the University of Tehran have developed indigenous software for providing real-time corrections for networks, precise positioning service and online processing of GNSS observations.
According to variousnews reports, the software is a modern, secure, and intelligent platform for processing observations from global positioning satellites, including GPS, Galileo, BeiDou and GLONASS.
Developed as a practical tool for surveyors, engineers, researchers and organizations in the field of satellite data monitoring, the software is intended to replace imported software and reduce dependence on foreign technologies. It has been tested by the network of permanent stations of the National Iranian South Oil Company.
The system processes observations using static, PPK, PPP and SPP methods, as well as observation quality control and enables the implementation of various positioning methods and real-time monitoring of ionospheric and tropospheric effects.
It supports all GNSS data types and can connect to reference stations in both client and server modes. It supports all existing and future GNSS signals and can handle at least 50 permanent stations and 200 users simultaneously. It also provides phase ambiguity resolution for baselines up to 70 kilometers.
Other technical features include providing a relative planimetric accuracy of 2 cm and a height accuracy of 3 cm using the static method with a maximum setup time of 15 minutes, a relative planimetric accuracy of 4 cm and a height accuracy of 5 cm using PPK and NRTK methods, and delivering corrections with a maximum permissible latency of 0.5 seconds.
The software has the capability to connect to reference stations through serial, TCP, and UDP ports, supports NTRIP protocol versions 1 and 2, displays an online map with a Google Map-like background, allows for viewing the location, status and information of CORS stations and active users, and enables generation of KML outputs.
CHC Navigation (CHCNAV) has released the Apache 6–2026 Edition, an integrated unmanned surface vessel (USV) designed for high-resolution bathymetric and 3D mapping applications. Built to accommodate NORBIT multibeam echosounders, the Apache 6 delivers a comprehensive solution for underwater surveying, object positioning, and offshore construction support in varying aquatic conditions.
The Apache 6 – 2026 Edition is optimized for seamless integration with the NORBIT iWBMS and WINGHEAD series of multibeam echosounders. An optional NORBIT iLiDAR can also be integrated, allowing for the simultaneous collection of marine and terrestrial 3D data in a single pass. This capability is particularly efficient for projects that require mapping both underwater topography and overhead structures, such as bridges and power lines, making it a comprehensive tool for harbor, river and infrastructure surveys.
Automated Sound Velocity Profiling Accurate sound velocity measurement is fundamental to high-quality bathymetric data. The Apache 6 – 2026 Edition addresses this with an optional automated sound velocity profiler (SVP) kit. This system can be controlled directly from the remote controller, allowing the operator to perform SVP casts on-demand without interrupting the survey workflow. The kit is designed for rapid deployment — attachable or detachable in under a minute — ensuring that the multibeam echosounder data is continuously corrected with the most accurate sound speed information, which is critical for meeting stringent survey specifications.
The USV combines a detachable triple-hull vessel design with smart rotating propeller technology to deliver both stability and agility in varied conditions. The robust hull configuration ensures reliable performance in strong currents, while removable side floats enable safe operations in shallow waters. Intelligent propeller control adjusts water flow direction to achieve a turning radius of approximately two meters, supporting effective navigation in confined or winding channels.
Android-Based Control Survey operations are streamlined through an intelligent Android remote controller, which provides real-time access to vessel status and data without the need for a separate field computer.
The interface allows for straightforward management of the survey workflow, while a multi-link communication system ensures reliable data transmission over long distances. This setup enables surveyors to maintain seamless control over the Apache 6 and monitor mission progress effectively from the shore.
Wingcopter’s authorized partner in Japan, ITOCHU Corporation, has signed a Memorandum of Understanding (MOU) to collaborate on the practical use of Wingcopter’s long-range drones in aerial surveying together with PASCO Corporation and YellowScan Japan.
The companies initially plan to use the Wingcopter 198 in disaster management where drone-based surveying is playing an increasingly important role,
to create hazard maps and monitor ground deformation as part of effective pre-disaster prevention,
to gather information and assess damage in the event of a disaster, and
to measure terrain changes and develop recovery plans during post-disaster restoration.
According to Wingcopter, carrying out these tasks is easier and less risky with fixed-wing drones such as the Wingcopter 198 than with traditional human or aircraft-based methods.
About 70 percent of Japan’s land consists of mountainous and hilly terrain, with steep slopes and short, fast-flowing rivers. Conventional multicopter droneswould not be suitable for such tasks as they are limited in range and coverage compared to the Wingcopter 198.

Under the MOU, YellowScan Japan’s advanced lidaer scanner Voyager will be used on the Wingcopter 198. By integrating this technology with PASCO’s extensive expertise in operational quality and safety in aerial surveying, it is possible to carry out long-distance and large-area surveys that were previously difficult to achieve without manned aircraft.
In a single 45-minute flight, the Wingcopter 198 can scan 1,000+ hectares, simultaneously capturing lidar and RGB data, allowing the system to generate an exceptionally high point density and precision. This makes it suitable even for demanding applications.
The collaboration also promotes automation and labor savings in surveying tasks, contributing to sustainable development in the surveying industry and reducing disaster risks.
Happy New Year! I’ve always felt that a fresh calendar represents a world of new opportunities, and I wish you all a fantastic 2026. For many, this is a season for reflection and self-improvement, with goals typically centered on fitness, faith, personal growth or career milestones.
As regular readers of this newsletter know, my primary focus over the past year has been to champion the importance of geodesy and to prepare the geospatial community for the National Geodetic Survey’s modernized National Spatial Reference System (NSRS).
To see how modern tech would handle such a specialized professional niche, I asked the AI chatbot Grok: “What would be a good New Year’s resolution for a user of the National Spatial Reference System?”
The response was quite insightful. Take a look at what it suggested below.
What would be a good New Year’s Resolution for a user of the National Spatial Reference System? (Grok’s Response)
Fun and Practical New Year’s Resolutions for NSRS Users
As we head into 2026, the modernization of the NSRS is in full swing. NOAA’s National Geodetic Survey (NGS) released the first beta products in June 2025, with ongoing rollouts and testing throughout the year. The full transition to new frames like NATRF2022 and NAPGD2022 is expected soon, bringing centimeter-level accuracy aligned with GNSS and global standards—but it requires preparation.
Here are some timely, geodesy-inspired New Year’s resolutions tailored for surveyors, GIS professionals, engineers, and anyone relying on the NSRS:
Fully transition workflows to the modernized NSRS. Commit to updating software, processes, and datasets for the new terrestrial reference frames and geopotential datum. Test tools on the NGS Beta site and provide feedback to help shape the final rollout.
Achieve new heights (and accuracies) in 2026. Embrace NAPGD2022 for more precise orthometric heights. Resolve to reprocess key projects with updated transformations (via NCAT or VDatum) and say goodbye to NAVD 88 quirks.
Stay grounded in best practices. Incorporate the latest NGS guidelines, like NOS NGS 92 standards for GNSS surveys. Attend webinars and workshops, or review resources, to keep your positioning sharp.
Contribute to the system. Submit high-quality GNSS data via OPUS-Share or participate in crowdsourced efforts to improve the network. Help make the NSRS even more robust for everyone.
Measure progress monthly. Track how the modernization impacts your work—review coordinate shifts, audit legacy data, and plan for smoother integrations in future projects.
These resolutions blend practicality with the spirit of improvement that defines geodesy. Happy New Year—may your positions be accurate, your elevations precise, and your datums forever modernized! For the latest updates, check geodesy.noaa.gov.
It’s no surprise that Grok highlighted the NSRS modernization; it even incorporated a photo of a geodetic benchmark I took for my July 2025 GPS World Survey Scenenewsletter.
Understanding that most AI chatbots personalize results using past interactions (unless disabled), I wanted to test this. After clearing my cache and deleting all previous Grok interactions, I posed the question again.
You can find that second, impersonalized response below.
Second Response from Grok
What would be a good New Year’s Resolution for a user of the National Spatial Reference System? Grok’s Second answer.
Here are some practical, realistic, and useful New Year’s resolutions tailored for someone who regularly works with the NSRS whether you’re a surveyor, GIS professional, geodesist, engineer or data manager:
“This year, I will stop mixing epochs without documenting them.” Resolve to always record the reference epoch (e.g., 2010.0, 2020.00) when I use NAD83(2011), NAD83(CORS96), NAD83(2011) epoch-specific coordinates, or when I transform to ITRF2020/2020.0. Bonus: add epoch to layer names and metadata.
“I will run OPUS or CSRS-PPP at least once a month to keep my local control fresh.” Make it a habit to periodically re-observe a trusted point and submit it to NOAA’s OPUS (or CSRS-PPP in Canada) to verify that my local network hasn’t drifted too far from the national datum.
“I will finally transition at least one active project to the modern NSRS (NAD83(2011)/NAVD88 → NATRF2022 / NAPGD2022).” Pick one ongoing or new project and do the full datum shift. Learn the tools (NADCON5, VERTCON3, GEOID18 → GEOID2022) and document what changed.
“I will replace every ‘NAD83’ label that doesn’t specify an epoch or realization with something more precise.” No more generic “NAD83” in reports, plats, or metadata. Aim for “NAD83(2011) epoch 2010.0” or “NAD83(2011) CORS-derived” — or better yet, start using NATRF2022 when appropriate.
“I will learn to use the NGS Coordinate Conversion and Transformation Tool (NCAT) fluently.” Commit to doing at least 5 conversions or transformations per month in NCAT instead of relying on old software or hand-calculated factors.
“I will check the NGS Data Explorer / Datasheet for every benchmark or CORS I plan to use — before I use it.” No more assuming a published value is still good. Make it a 2-minute ritual to look up the latest adjusted position and velocity.
“I will attend at least one NGS webinar or read one Bluebook chapter in 2026.” The NGS webinar series is free and excellent. Pick one session (e.g., on GEOID2022, NATRF2022 implementation, or GNSS vector processing) and actually watch it.
“I will prepare a small ‘before/after’ datum comparison report for my organization or clients.” Quantify what the 2022–2025 NSRS modernization means in your typical project area (horizontal shift, orthometric height change). Even a one-page summary builds understanding and credibility.
“I will stop treating GEOID18 as the final word and start using GEOID2022 for new work.” Especially important for projects that will live past 2025, as NGS is phasing out support for older geoids.
Pick one or two that feel achievable and most relevant to your day-to-day work. My personal favorite starter resolution for most NSRS users in 2026: “In 2026, I will clearly label the datum, realization, epoch, and geoid model on every deliverable I produce.”
That one habit alone dramatically reduces confusion downstream.
I really appreciate Grok’s responses because they address crucial issues that many geospatial users either overlook or take for granted, emphasizing the importance of proper documentation and associated metadata.
Key Resolution Examples:
Specificity: “I will replace every ‘NAD83’ label that doesn’t specify an epoch or realization with something more precise.”
Verification: “I will check the NGS Data Explorer / Datasheet for every benchmark or CORS I plan to use — before I use it.”
It is important to note that the AI chatbot assumes the modernized NSRS has already been adopted, which, as of January 2026, is not the case. This highlights that AI still has limitations and requires human oversight.
I challenge you to ask your own AI chatbot a similar, niche question related to your profession and compare its responses.
Beyond the specific technical corrections, Grok provided excellent general advice for any geospatial professional. Take, for example, action items 1 and 5 from its first response:
Transition Workflows: Commit to fully updating software, processes, and datasets to align with the new terrestrial reference frames and geopotential datum.
Measure Progress Monthly: Track the real-world impact of modernization by reviewing coordinate shifts, auditing legacy data, and planning for smoother integrations in upcoming projects.
Even though the modernized NSRS has not yet been officially adopted as of January 2026—with official release and FGCS approval expected later this year—following these steps now ensures you are prepared for the official transition when it occurs.
To help your team prepare for the official transition later this year, I’ve included a box titled “Questions to Guide a Self-Assessment of Your Operation and Products.” These questions, originally featured in my October newsletter, are designed to ensure your organization is fully equipped to implement the new NSRS the moment it is adopted.
Are you generating or using geospatial data (or doing both)?
If so, your workflows are likely dependent on geodetic control tied to one or more NGS products. The upcoming NSRS update will affect these dependencies. (See the box titled “List of NGS Products and Services.”)
Do you know if your mission, project, or datasets depend on NGS products?
Identifying whether and how your entity relies on NGS products is a critical first step in assessing potential impacts.
What are your accuracy, precision, and shelf-life requirements for geospatial data?
Understanding your mission’s specific data requirements ensures you can evaluate whether NSRS modernization will meet your operational needs without unnecessary adjustments. This should include plans to accommodate greater accuracy in the future.
Do you know how your entity accesses and utilizes geospatial data?
Are you obtaining it directly from NGS or indirectly through third-party vendors (e.g., RTN systems, GIS platforms, GNSS companies)?
Many entities rely on geodetic control without realizing it. NGS’s foundational data and frameworks are often invisible and seamlessly embedded within the tools and services offered by third-party vendors, such as GIS platforms, survey equipment, and software providers. These vendors, in turn, depend heavily on NGS products like the NSRS to ensure their tools are accurate and functional. Understanding this indirect reliance is crucial for preparing your workflows and ensuring continuity as the NSRS is modernized.
Where does your entity fit in with the geodetic workflow?
Does your entity create integral products (e.g., GNSS data, Lidar data) on which other products depend?
Evaluating these dependencies will help you determine the scope of NSRS modernization impacts.
What are your project requirements for data accuracy and longevity?
Assess whether your data accuracy thresholds and long-term usability align with the modernized NSRS.
Have you evaluated workflows and identified potential impacts in areas affected by significant ground movement (e.g., regions with tectonic shifts, vertical land motion, and, most notably, subsidence)
Identifying potential risk or disruption areas can guide prioritization and help mitigate impacts on critical operations.
While the original meeting scheduled for October 15, 2025, was canceled due to the Federal Government Shutdown, it has been officially rescheduled for Wednesday, January 21, 2026. This meeting will be critical for aligning agency engagement strategies and self-assessments ahead of the final adoption of the new datums.
Increase awareness of the National Spatial Reference System (NSRS) Modernization rollout schedule and engagement strategy, including self-assessment and interaction between official departmental working groups and an NGS point of contact.
Within other Departments, connect decision-makers to those who accomplish NSRS modernization tasks and designate points of contact to interface with NGS capacity-building efforts.
Share experiences and strategies among federal agencies concerning NSRS Modernization self-assessment and preparation.
(New) Formally transition the foundational beta products (released in May 2025) from preliminary to final.
Gather questions, discuss anticipated challenges, and identify opportunities to support each other through this transition.
The FGCS plays a central role in coordinating geodetic activities across the federal government, including the development of standards and the promotion of the use of authoritative geodetic control (e.g., CORS, geoids) to ensure that geospatial data is accurate, accessible, and interoperable, and to advance the modernization of NSRS across agencies and recommend the adoption of the modernized NSRS by FGDC as the official basis for geodetic control in the United States. It is my understanding that this meeting is open to the public (virtually) for listening and observation. The box titled “Federal Geodetic Control Subcommittee Meeting” provides the agenda of the January 21, 2026, meeting.
Federal Geodetic Control Subcommittee Meeting Agenda held January 21, 2026.
To join the meeting virtually, registration is required. You can find all the necessary details and a direct link to sign up in the box titled “Registration for the Virtual Attendance of the Meeting.”
NOAA’s National Geodetic Survey (NGS) invites you to the upcoming Federal Geographic Data Committee (FGDC) Federal Geodetic Control Subcommittee (FGCS) meeting.
In October 2025, NSPS held its Fall meeting. The box titled “Excerpts from 2025 NSPS Fall Meeting Report: October 17, 2025” contains excerpts from the report provided by Richard Kleinmann, Wisconsin NSPS Director, on the working group’s activities being performed by the National Society of Professional Surveyors (NSPS) Professional Standards NSRS Modernization Subcommittee.
Submitted by: Richard Kleinmann PLS, Wisconsin NSPS Director
Subcommittee Purpose: To promote awareness, adoption, and readiness for the implementation of the Modernized National Spatial Reference System (NSRS) in cooperation with the National Geodetic Survey (NGS) and other geospatial groups.
Activities: NSPS leadership and the NSRS Modernization Subcommittee continue to work closely with NGS to promote awareness, adoption, and readiness for the new 2022 datums, which are expected to be approved sometime in 2026. Due to federal funding challenges occurring in 2025, NSPS felt it necessary to intensify its support of NGS and the modernization of the NSRS which was the genesis of this subcommittee.
The NSRS Modernization Subcommittee is also working on a series of documents originally developed by Dana J. Caccamise of NGS intended to be used by Federal Agencies in the transition to the new datums. We are adapting the documents to change the “voice” from NGS to NSPS and the intended audience to state, regional, county and local agencies, as well as private practitioners, to help them transition smoothly to the modernized NSRS. At this point, the document package includes:
Briefing materials for agency coordination (Presentation Template)
These document resources are being developed with the hope to share them via NSPS social media outreach efforts and possibly a geospatial information “hub” shared by NSPS and other geospatial organizations.
Proposed Whitepapers/Use Case Reports: The intent of these whitepapers is to is to provide a somewhat higher-level view of how the transition to the new datums/frames can be accomplished by showing what tools are available and what to consider when designing a project approach. Our hope is to promote the adoption of the new datums and share the benefits of doing so. Basically, adopting a “be prepared, not scared” attitude. We are looking for people willing to share their solutions so others can benefit from their experience and be more likely to be early adopters. It is not our intent to develop detailed step by step recipes that can be blindly followed because every geographic region has their unique circumstances that need to be considered but the white papers will instead supply the foundation for them to confidently build a project approach that works in their situation.
Coordination with other working groups: NSPS is looking forward to coordinating with similar Working Groups that NGS has encouraged to be formed by the American Society for Photogrammetry and Remote Sensing (ASPRS) and the American Association for Geodetic Surveying (AAGS). There are several Task Forces and Committees formed on the state level that are also working on adoption and implementation issues specific to their states. Together, these efforts aim to build understanding, reduce uncertainty, and support the geospatial community’s successful implementation of the updated reference framework. NSPS and NGS have committed to having a significant presence at Geo Week in Denver, Colorado, on February 16-18, 2026.
As mentioned in the working group’s report, “As an outgrowth of interaction between NSPS & NGS during NGS quarterly meetings and at geospatial events such as the ESRI User Conference and Geo Week, the NSPS leadership team and subsequently the NSRS Modernization Subcommittee began developing a suite of resources — including an ArcGIS StoryMap with several resources useful for the transition. See the link for the NSPS ArcGIS Story map here: https://share.google/oOAIapPQnux5q8nwl.
The box titled “NSPS ArcGIS Story Map” offers a detailed look at this resource, which visually illustrates the impact and benefits of the upcoming NSRS modernization.

The website has five buttons:
Overview
What to Expect
How to Prepare
Resources
Note to Users
The section titled “The Overview Section” details the essential information — who, what, where, when, and why — regarding the new, modernized NSRS. Additional information is available on the website.
Overview
WHO: The National Geodetic Survey (NGS), located within the National Oceanic and Atmospheric Administration (NOAA) of the United States government. The NGS is responsible for defining, maintaining, and providing access to the country’s positioning infrastructure called the National Spatial Reference System (NSRS).
WHAT: Is updating the NSRS – horizontal (geometric, NAD 83) and vertical (geopotential, NAVD 88 and local island vertical datums PRVD02, USVI09, ASVD02, GUVD04, HAWAII – Local Tidal) geodetic datums, an effort that has been underway since 2007.
WHERE:The North American, Pacific, Caribbean, and Marianas plates.
WHEN: Now – rollout is underway. An updated Federal Register Noticewas released on October 9, 2024. Alphaand Betaproducts are being released, with full replacement of the NSRS anticipated in 2026.
WHY: These datums have been in use since GPS was in its infancy – i.e., for decades, and there are known limitations that the new system addresses:
NAD 83 is not as geocentrically defined as today’s positioning technologies demand, meaning not referenced to the center of Earth’s mass, by about 2.24 meters based on the latest international estimates. This is problematic when using Global Navigation Satellite Systems (GNSS), which orbit about and provide positions relative to the center of the Earth.
NAD 83 grouped the North American and Caribbean plates in its definition. The updated system has broken those two plates out (because we now understand how to measure how the plates rotate individually) in addition to the Pacific and Marianas plates included in NAD 83, resulting in definitions for four Terrestrial Reference Frames (TRFs): NATRF2022, PATRF2022, MATRF2022, and CATRF2022.
Continental drift and vertical land movement were not accounted for in the existing NSRS. Reference epochs (timestamps, for instance) for coordinates have been introduced for survey data to help us better understand movement or change over time.
Based on current international geoid estimates, NAVD 88 is biased by approximately 1.5 meters and tilted by 1 meter coast-to-coast.
There are currently multiple vertical datums. The new system will consist of one.
NAD 83 and NAVD 88 were designed independently, resulting in reduced accuracy. In the new system, they were designed together, resulting in better integration and higher accuracy.
GEOID 18 and previous models were hybrid models “warped” to match leveled benchmarks. GEOID2022 will be a more consistent and stable model as it is a purely gravimetric geoid model.
Currently, both physical marks and continuously operating GNSS stations are relied upon for the existing NSRS. Physical marks degrade and are destroyed over time, negatively affecting height and position data. The modernized NSRS will rely exclusively on GNSS stations.
State Plane Coordinate System 83 (SPCS 83) includes high levels of distortion for many areas. The modernized SPCS2022 minimizes distortion or scale error (the difference between ground and grid measurements) at the topographic surface rather than the reference ellipsoid surface, and is designed to minimize distortion in populated or high-use areas.
An important change between SPCS 83 and the upcoming SPCS2022 is that only the international foot (1 foot = 0.3048 meter, exactly) will be supported, which differs from SPCS 83, with some states officially using the international foot while others use the U.S. survey foot (1 foot = 1200/3937 meters). This is consistent with the deprecation of the U.S. survey footinitiated by the National Institute of Standards and Technology (NIST) at the end of December 2022.

Hexagon has joined the Multilateral Memorandum of Understanding (MMoU) on Strengthening the Global Geodesy Supply Chain.
The MMOU is a shared recognition by the United Nations Global Geodetic Centre of Excellence (UN-GGCE) — alongside member state government departments and agencies, private sector companies, organizations, associations, and academic institutions — that action is required to make the foundations of positioning, navigation and timing services robust.
With HxGN SmartNet, Hexagon has built a reliable, scalable GNSS infrastructure that integrates physical reference stations, specialized software such as Leica Spider, and a secure environment for distributing precise positioning data. Supporting tens of thousands of users worldwide, SmartNet delivers the accuracy and continuity essential for daily operations across many sectors.
The MMoU signatories hope to advance resilient positioning services and strengthen geospatial capabilities for nations around the world. Through joint initiatives, they aim to:
Enhance continuity and accuracy of GNSS-based positioning services
Strengthen resilience against signal interference
Support countries in developing and maintaining geodetic infrastructure
Expand education and workforce development in geodesy.
These initiatives ultimately help end users access more consistent accuracy, higher service availability, and stronger resilience against jamming or spoofing.
The MMoU was signed by Henning Sandfort, president, Geosystems Business Area, Hexagon, and Dieter Fritsch, Hexagon’s representative to the UN-GGIM Private Sector Network, on Nov. 17.
“Joining the MMoU underscores our commitment to ensuring that accurate, dependable geospatial information is accessible to governments and organisations worldwide,” Sandfort said.
“Hexagon’s contribution under the MMoU demonstrates the importance of global collaboration between Member States, UN and the geospatial industry,” said Nicholas Brown, head of Office at the UN-GGCE. “Hexagon is a key player of GNSS technology and digital reality solutions and therefore mostly welcomed to contribute the future vision of a strengthened global geodesy supply chain.
Tersus GNSS has launched the MVP S1 RTK-SLAM handheld 3D laser scanner for mobile mapping and reality capture. The MVP S1 uses GNSS through an AI-driven RTK-SLAM workflow, as well as lidar data with imagery from dual 48-megapixel panoramic cameras.
The combination provides survey-grade results in both GNSS-denied and open environments. The system achieves centimeter-level accuracy outdoors and maintains performance indoors or underground through SLAM processing.
TimeSync 3.0 synchronizes the hardware, aligning sensor data at the microsecond level and supporting consistent datasets and reliable post-processing.
A mobile application provides users with real-time feedback, including previews of colorized point clouds while scanning, as well as basic scan reports on site. This feature helps operators verify data completeness and quality before leaving the field, reducing the need for repeat visits.
The MVP S1 supports 3D gaussian splatting (3DGS), enabling creation of textured, photorealistic 3D models. This capability is useful for building information modeling, construction progress monitoring, underground surveys, forestry analysis and industrial site documentation.

My May 2025GPS World newsletter highlighted the American Association for Geodetic Surveying (AAGS) “Certificate for Geodetic Surveying” Program. This newsletter will update readers on the program. As I mentioned in the May 2025 newsletter, the Certificate for Geodetic Surveying program is designed to meet the needs of surveyors and others who perform spatial analyses and computations using geodetic methods.
Some of you may not be familiar with AAGS. The American Association for Geodetic Surveying (AAGS) aims to guide the community of geodetic, surveying and land information data users into the 21st century by working together to develop new educational programs — such as presentations, seminars, and workshops on geodetic surveying — and by publishing articles and papers that share the latest scientific and technological advances, along with advice for cost-effective, efficient implementation. AAGS also encourages a deeper understanding of geodesy by offering educational materials in geodesy, geodetic surveying and related fields.
The AAGS Board meets on the second Wednesday of each month at 4:00 p.m. (Eastern Time). Please visit the AAGS website and consider joining our monthly board meetings — a forum to share ideas and learn about geospatial products and services. All are welcome. To be added to the attendee list, email me at [email protected].
Here’s the latest on the certification program: AAGS has developed questions covering the seven core areas of minimum competence in geodetic certification: (1) Geometric Geodesy, (2) Physical Geodesy, (3) Accuracy and Error, (4) Temporal Aspects, (5) Global Navigation Satellite Systems, (6) Geodetic Survey Networks, and (7) Standards and Guidelines. For details on each topic, see my May 2025 GPS World newsletter. The information below includes examples the Board is considering for the exam.

Geodetic Survey Networks
In a GPS network adjustment, primary reason for the minimally constrained adjustment is to ensure that
a) the baseline components are free of large errors
b) the control point coordinates have no errors
c) the degree of freedom of adjustment is correct
d) integer ambiguities have been determined correctly
Standards and Guidelines
Which of the following statements about the State Plane Coordinates System (SPCS) is false?
Eliminates having individual adjacent surveys based on different assumed coordinates
Extensive highway projects can start at one control point and close on another at some distance away.
If a monument is lost, one can use other SPCS monuments to recover the lost monument.
Since SPCS utilizes a “developable surface” to project ground points onto a plane, the resulting projection is “distortion free”
The draft questions are under expert review to ensure they target the right geodetic concepts and effectively assess the knowledge needed by those creating geospatial products and services. Our aim isn’t to make everyone a geodesist, but to ensure anyone producing geospatial products understands enough geodesy to create, depict, and document them correctly. AAGS is partnering with NSPS to implement the program, aiming for a 2026 launch. I’ll share updates in future emails.
We’ve discussed producing shorter YouTube sessions focused on key concepts from the seven competency areas of the geodetic certification program. These would complement the existing member-only educational videos on the AAGS website. For details, see the Resources tab on the AAGS website.
