SparkFun Electronics has introduced its real-time kinematics (RTK) evaluation kit (EVK). It serves as a development platform for fixed or mobile high-precision positioning and navigation needs. The RTK EVK comes with a range of options for prototyping, including L1+L2 RTK GNSS, with L-Band correction built-in if needed, running on an agile processor.

It features custom open-source software pre-loaded with RTK Everywhere firmware. Users can configure the EVK as an RTK Base and push corrections to an NTRIP Caster or configure the EVK as an RTK Rover and use corrections delivered through WiFi or Bluetooth.

The kit uses the dual-band (L1+L2) ZED-F9P GNSS receiver from u-blox. The integrated u-blox NEO-D9S offers L-Band reception and access to correction services such as PointPerfect. The u-blox LARA-R6001D provides global cellular connectivity.

Zero-Touch RTK offers users a simple way to receive corrections. Users can register the device, plug it into Ethernet (PoE supported) or give it WiFi credentials for a hot spot and enable PointPerfect – no NTRIP credentials are required.

The RTK EVK can be easily installed in a weatherproof enclosure with its custom extruded aluminum case with machined end panels and slotted flanges.

Eos Positioning Systems has released the Skadi Series product line. The Skadi Series consists of high-accuracy GNSS receivers designed to enhance field crews’ productivity, safety and flexibility.

Skadi Tilt Compensation allows users to capture data without needing to level their survey range pole. When activated on an RTK-enabled Skadi Series receiver, this feature allows users to rely on the receiver to correct errors caused by tilted range pole angles during data collection.

The Skadi Smart Handle introduces two additional features, powered by accurate lidar and MEMS sensor measurements. With the Skadi Smart Handle, users can activate an Invisible Range Pole to provide continuous elevation-to-the-ground measurements below the hand–held Skadi receiver.

The receiver computes accurate elevation to the ground, regardless of its attitude (angle toward the ground). The Invisible Range Pole eliminates the need to carry a physical range pole and the requirement to enter an antenna height in a field data collection app while performing RTK-level accurate fieldwork.

The Skadi Smart Handle also includes an Extensible Virtual Range Pole. This feature extends the reach of the user’s Invisible Range Pole beyond the position they physically occupy. The Extensible Virtual Range Pole allows users to measure the location of assets on the ground or in trenches up to 7m (23 ft) away while retaining high accuracy.

The series adds four new GNSS receivers with integrated antennas to the Eos offerings: the Skadi 100, Skadi 200, Skadi 300 and Skadi Gold with accuracies ranging from submeter to centimeter. The Skadi 200, Skadi 300 and the Skadi Gold are RTK enabled and are available for purchase with Skadi Tilt Compensation and the Skadi Smart Handle.

NGS new alpha preliminary products in support of the modernized NSRS
Photo: SonjaBK / iStock / Getty Images Plus / Getty Images

In my last newsletter, I highlighted the release of a beta version of a new NOAA CORS Network (NCN) Station Web Page. As demonstrated in my newsletter, each CORS in the NCN has its own page with data, metadata, maps and photos for that station displayed in a modular layout so information is easily found all in one location. This past month, I had the privilege of participating in a meeting with representatives from the American Association for Geodetic Surveying (AAGS), the National Society of Professional Surveyors (NSPS) and the National Geodetic Survey (NGS). As a Past President of AAGS and the current Chair of the AAGS Membership Committee, I participate in these quarterly meetings.

AAGS aims to lead the community of geodetic, surveying, and land information data users through the 21^st century. AAGS members develop new educational programs, including presentations, seminars, and workshops on topics related to geodetic surveying; and articles and papers that inform the membership of the latest scientific and technological developments and how to implement them in the most cost-effective and efficient manner.

In my previous newsletters, I have reminded everyone that time is running out to obtain a working knowledge of the new, modernized National Spatial Reference System (NSRS). The release of the new, modernized NSRS is only about a year away. As of July 2024, NGS plans to have a beta version of the new, modernized NSRS available around the summer of 2025 for users to test and evaluate new products and services. After enough testing has been performed, the new, modernized NSRS will be officially published – probably in early to mid-2026.

At the meeting, NGS highlighted some new products on its Alpha Preliminary Products site. The alpha site provides products that are useful for individuals who want to obtain a better understanding of the products that will be distributed as part of the new, modernized NSRS.

Some of my previous newsletters have discussed the Alpha product concept. My September 2023 newsletter highlighted the first two Alpha products; that is, State Plane Coordinate System of 2022 (SPCS2022) and NGS Coordinate Conversion and Transformation Tool (NCAT). As of June 2024, two more products have been added to the Alpha Preliminary Products site – “GEOID2022 Alpha” and “Alpha Values for EPP.” The State Plane Coordinate System of 2022 (SPCS2022) is probably the most important to land surveyors. There are significant changes between the SPCS2022 and the State Plane Coordinate System of 1983 (SPCS83). I will highlight the latest options in the alpha site later in this newsletter.

First, I want to bring attention to the importance of ensuring that the state’s legislation is modified or rewritten, if required, to include that the current horizontal and vertical datums are being replaced with the new, modernized NSRS. The “Learn More” button on the SPCS2022 Alpha site provides information about legislation.

On the “Learn More” site, NGS provides an SPCS legislation template.

Per personal communication with Michael Dennis, Ph.D., NGS SPCS2022 Manager, as of June 26, 2024, the following 12 states have have enacted into law NSRS modernization: Alaska, Idaho, Iowa, Kansas, Kentucky, Louisiana, Nebraska, North Carolina, South Dakota, Vermont, Washington, and Wyoming.

Users can download examples of actual new state legislation here.

Examples of legislation.

During the joint AAGS/NSPS/NGS meeting, Tim Birch, the executive director of NSPS, said that anyone who has questions about updating legislation for the new, modernized NSRS, including SPCS2022, can contact him directly. NSPS has experience working with agencies and individuals to develop legislation as indicated in the following statement on the NSPS website.

“We are the voice of the professional surveying community in the US and its territories. Through its affiliation agreements with the respective state surveying societies, NSPS has a strong constituency base through which it communicates directly with lawmakers, agencies, & regulators at both the national and state level. NSPS monitors and comments on legislation, regulation, & policies that have potential impact on the activities of its members and their clients, and collaborates with a multitude of other organizations within the geospatial community on issues of mutual interest.”

Tim’s contact information is provided on the NSPS home webpage: Staff List – National Society of Professional Surveyors (nsps.us.com).

As previously stated, the two latest alpha products are the “GEOID2022 Alpha” and “Alpha Values for EPP.” My December 2017 newsletter discussed GEOID 2022 and the North American-Pacific Geopotential Datum of 2022 (NAPGD2022), and my February 2022 newsletter discussed the Euler Pole Parameters process and use in the new, modernized NSRS.

The GEOID2022 Alpha page provides a version of GEOID2022, which is the most recent prototype of the geoid models. The reference ellipsoid is Geodetic Reference System 1980 (GRS 80, but the geometric reference frame is ITRF2020). The Alpha GEOID2022 prototype data is available for download in two formats, “ASCII” and “.b.” There is a static component (SGEOID2022) and a dynamic component (DGEOID2022). These grids will be useful to programmers who want to develop and test their systems. Additional grids and tools will be available in the future.

Technical Details of the Alpha prototype of GEOID2022

GEOID2022 alpha is the last prototype of GEOID2022. It covers three regions: the North America–Pacific region, Guam and Northern Mariana Islands, and American Samoa. The spatial resolution of the geoid model is 1 arcminute. The geoid heights, which are in the tide-free system, are with respect to the reference ellipsoid of the Geodetic Reference System 1980 (GRS80) in the ITRF2020 geometric reference frame. GEOID2022 alpha includes static and dynamic components for the geoid heights. For detailed fundamental parameters of the geoid model, refer to NOAA Technical Report 78.

GEOID2022 Alpha

The Alpha EPP site provides the Euler Pole Parameters (EPP) that are needed to define the relationship between the ITRF2020 and models on the North America, Caribbean, Pacific and Mariana plates as discussed in NGS’s Blueprint Part 1 document.

Alpha Values for EPP

As stated in Blueprint Part 1, NGS will define the official relationship between ITRF2020 and the four NSRS TRFs through equation 59, using the rotation matrix in equation 58 resulting in equation 60.

I programmed this using a simple Excel spreadsheet to compute some of the potential changes between epochs for North Carolina. They were very similar to the ones that I depicted in my February 2022 newsletter that discussed the Euler Pole Parameters process and provided plots depicting the movement.

I would like to highlight the latest information available on the State Plane Coordinate System of 2022 alpha site. As previously stated, in about a year, the new, modernized NSRS will be available as a beta product. Users must get prepared by accessing NGS’s alpha products as well as taking the opportunity to provide feedback to NGS to improve their products and services. The Online Interactive Maps page provides information about the zones for every U.S. state and territory.

Clicking on the Online Interactive Maps link opens a NOAA ArcGIS online website that provides information about the Alpha State Plane Coordinate System 2022 preliminary zone designs. I have highlighted a few items that may be of interest to users.

The site provides a description of the site, links to various types of zones, links to data sources and information about distortion.

SPCS2022 online interactive maps.

Clicking on the link for zone definitions provides a list of zones and their parameters. This same information is also provided when users click on a zone on the map. I will demonstrate this later in this newsletter.

Per personal communication with Dennis, as of June 26, 2024, seven states have some or all their SPCS2022 zone definitions formally finalized, consisting of 205 out of the 965 zones (the total number of zones is still preliminary):
- Alaska (partial coverage multizone layer)
- Arizona (both multizone layers)
- Idaho (both multizone and statewide)
- Kentucky (both multizone and statewide)
- North Carolina (statewide zone; it has no other zones)
- South Dakota (both multizone and statewide)
- Wisconsin (multizone)
Dennis informed me that the information on the alpha SPCS2022 Experience has been updated. He told me that the total number of zones decreased from 967 to 965, but based on coordination with the International Association of Oil & Gas Producers (IOGP) Geodesy Subcommittee the number may eventually increase to 972 (more about that in a future newsletter).

He stated that his goal is to finalize the zone definitions by the end of this calendar year or early 2025. Users should keep checking the alpha site.

Dennis mentioned that the website now offers a new feature that provides the distortion value when users click on the map. A nice thing about that is the site can be used on a smartphone, allowing users to obtain real-time distortion information from their location.

Clicking on the link titled “View” in the upper right corner of the box brings up a map that depicts the SPCS2022 zones.

View of ALPHA (preliminary) SPCS2022 zone designs.

When you click on the note about the ALPHA being preliminary, the map underneath appears where the user can select the type of maps they wish to review.

The following options are available: All Zone Layers, Statewide Zone Layers, Multizone Complete Layers, Multizone Partial Layers, and Special Use Zone Layers.

Users can use their mouses or the “+” button on the left-hand side” to zoom to a particular region, or use the search button on the right-hand side to select a State or zone.

Using the search box.

Information about a particular zone pops up by clicking on a point on the map.

Detailed information provided for a zone.

Each zone provides links to other features based on the location of the point selected on the map.

The image below provides the distortion in ppm for the point selected on the map.

The Alpha NCAT site can be used to obtain an estimate of the changes between SPCS83 and SPCS2022. It should be noted that all values will be in meters (m) and international feet (ft).

International feet may be new to some surveyors who were previously using the U.S. survey feet in SPCS83. The U.S. survey foot will not be used with the NSRS, including SPCS2022 coordinates. NGS and the National Institute of Standards and Technology (NIST) have taken action to deprecate the U.S. survey foot. What does that mean?. NIST has the following statement on its website: “Beginning on January 1, 2023, the U.S. survey foot should be avoided, except for historic and legacy applications, and has been superseded by the international foot.” This means that NGS will not be publishing SPCS2022 in U.S. survey feet but all historic products and services such as SPCS83 will still be provided in U.S. survey feet (sft) and international feet (ift).

More information and resources about the deprecation of the sft are listed below (personal communication from Dennis):
- The official announcement is the final determinationFederal Register Notice (FRN) on deprecation of the sft issued on 10/5/2020. It was jointly issued by the National Institute of Standards and Technology (NIST) and NGS. I encourage everyone concerned about this topic to read it closely and in its entirety; it can likely answer most questions. The FRN includes information on the continued use of sft for legacy applications (such as SPCS 83). That is stated in the last paragraph of the “Notice of Final Determination” section; in items #1 and #2 in the “Counterpoints to Feedback Expressing Opposition”section; and in the second paragraph of the “Implementation Summary and Actions” section.
- The legacy issue is also addressed in the 10th FAQon the NIST website and in the 11th FAQon our “new datums” FAQs web page.
- The 40 states that officially adopted the sft for SPCS 83 are listed in Table C.1 of Appendix C of NOAA Special Publication NOS NGS 13, “The State Plane Coordinate System History, Policy, and Future Directions.”
- Although the final determination FRN is itself not a law, Congress has passed several laws giving NIST the authority to maintain national standards of measurement. These and other related federal laws are given in the initial sft FRNissued on 10/17/2019.
- An NGS webinar given on 11/10/2022 addresses the deprecation of the sft in the context of state plane. Two previous NGS webinars also provide additional background and historical information on the sft, one given on 4/25/2019 and the other on 12/12/2019.

The U.S. Geological Survey (USGS) has commissioned Woolpert to collect Quality Level 1 lidar data and conduct ground control surveys throughout Southern California in support of the 3D Elevation Program (3DEP) and The National Map.

Overseen by the USGS National Geospatial Program, 3DEP provides the nation’s first comprehensive, high-resolution topographic elevation data integrated into The National Map. The data will be accessible to local, state and national agencies to consider when making decisions that affect the immediate safety of life, property and the environment, as well as for long-term infrastructure planning.

Woolpert will collect roughly 60,000 km² of aerial lidar data throughout Inyo County, California, including parts of the Mojave Desert and Death Valley National Park, using a Leica TerrainMapper. QL1 data are collected at eight points per square meter.

“Woolpert has had the honor of supporting USGS’ 3D Elevation Program since its launch nearly a decade ago,” said John Gerhard, Woolpert vice president and program director. “Critical decisions that depend on accurate and available elevation data are being made every day, and we are incredibly proud to continue our support for the U.S. Geological Survey and its commitment to completing the nation’s first-ever baseline of consistent high-resolution elevation data.”

Gerhard added that the data acquired for this project will also support the USGS 3D Hydrography Program (3DHP). The project is underway, and data is expected to be acquired by fall 2024.

Trimble has introduced the Trimble R980 GNSS system, the newest addition to its GNSS receiver portfolio. The R980 features communication capabilities to support uninterrupted field operations.

The Trimble R980 can be used for land surveying, transportation infrastructure, construction, energy, oil and gas, utilities and mining projects. It features Trimble’s ProPoint GNSS positioning engine and inertial measurement unit (IMU)-based tilt compensation using Trimble TIP  technology. These features make it suitable for dense urban environments and under tree canopy, removing the need to level the pole when capturing data points.

The R980’s communication capabilities include a dual-band UHF radio and an integrated worldwide LTE modem for receiving corrections from a local base station or VRS network. Able to operate on 450 MHz, 900 MHz or LTE bands, users have flexibility in how they receive and transmit RTK corrections. It operates in both 450 MHz and 900 MHz bands, allowing for interoperability with a range of existing industry solutions.

The R980 also supports the Trimble Internet Base Station Service (IBSS) for streaming RTK corrections using Trimble Access field software for connected workflows.

A 12-month subscription to Trimble CenterPoint RTX real-time corrections, delivered via satellite or internet, is included on new R980 receivers. This provides reliability without the need for a local base station or VRS network, the company says. The service provides centimeter-level corrections and is complemented by the Trimble xFill correction service that extends RTK positioning during signal interruptions.

The receiver includes Trimble IonoGuard technology, which mitigates ionospheric disturbances for RTK GNSS and Trimble Everest Plus for multipath mitigation performance. IonoGuard technology improves positioning availability in periods of increased solar activity, such as the recent G5 geomagnetic storms that occurred around the world.

The Shift5 GPS integrity module is a platform-agnostic solution for military, aviation, rail, maritime and space applications.
With real-time access and analysis of onboard data, the module assesses changes in navigational position through multi-faceted anomaly detection methods, which alert operators to GPS spoofing attacks as they happen.

Using data collected from onboard systems, the module uses algorithmic position analysis to identify significant position deviations and GPS data validation to verify GPS information accuracy. Discrepancies or deviations that indicate tampering trigger an immediate notification, allowing operators to initiate standard operating procedures (SOPs) rapidly and accurately.

The module is designed for cross-platform deployment, across commercial and military planes, locomotives, vessels and aircraft, as well as on other critical systems such as radar, unmanned aircraft systems (UAS) and weapon guidance systems. It seamlessly integrates with existing platforms and can deploy directly to onboard hardware.

It offers multi-faceted detection and alerts for GPS spoofing attempts, designed to improve the safety and reliability of navigation systems. It uses physics-based spoofing detection to determine whether reported changes in position are physically possible to provide an effective method for initial spoofing detection. The system analyzes data from all sources to detect subtle, sophisticated spoofing attempts, which is essential for identifying more complex spoofing strategies that may evade traditional spoofing detection techniques.

Shift5 alerts can be integrated into existing SOPs to help preempt contamination of other positioning and navigation data, such as inertial navigation calibration against false GPS data. Metadata about the time, location, duration and estimated position of the attack can be passed for inclusion in threat mapping and other geospatial systems for future route avoidance.

Surveying & Mapping: Overlapping technologies and professions

For decades, surveying — which consists largely of making measurements to determine the relative positions of points above, on or beneath Earth’s surface — had much higher accuracy than mapping for geographic information systems (GIS) — which is mostly based on aerial photogrammetry for base maps and field data collection of the locations of features. When I started in this field a quarter century ago, we typically classified GPS receivers as survey grade, resource grade or consumer grade, with “resource grade” referring to field data collection for GIS.

Today, however, the accuracy of all receivers has greatly increased — thanks to improved chipsets, new GNSS constellations, and a plethora of corrections services — and those three categories are no longer relevant. Therefore, surveying and mapping are increasingly overlapping.

For this cover story, I asked the same three questions about mapping and surveying to representatives of four companies.

Surveying and mapping are increasingly overlapping. What are the remaining differences between them, in terms of accuracy requirements and challenges in the field?

CHC Navigation
While advances in technology such as lidar and photogrammetry are narrowing the gap, there are still notable differences between surveying and mapping. Surveying often requires centimeter- or even millimeter-level accuracy at specific points. In contrast, mapping focuses on collecting dense 3D data over large areas. Although the accuracy of mapping point clouds is steadily increasing, the integration of ground-based GNSS data collection with aerial imagery and lidar is becoming widespread. Mapping tends to be less labor-intensive and involves fewer safety risks in the field, but it requires a unique skill set, particularly in point cloud processing.

Hexagon
Traditionally, surveying and mapping differ primarily in their accuracy requirements and application scales; however, this paradigm is changing with mapping becoming increasingly accurate. Surveying focuses on high-precision geospatial data of specific points. From road, rail and tunnel construction to high-rise buildings, there is no substitution for the precision delivered by surveying equipment and procedures. In contrast, mapping focuses on larger areas.

Recent advancements in sensor technology, including both airborne and mobile mapping systems such as the Leica CityMapper-2 and the Leica Pegasus TRK, have significantly improved the efficiency and precision of mapping, bringing it closer to the levels achievable with traditional surveying equipment.

OxTS
Surveying comes with a large overhead during the data collection process. It requires meticulous preparation and attention to detail to achieve high accuracy in the raw data. GNSS quality, lever arms, user operation, etc., can all cause problems later on. Getting any part of the process wrong can have major cost implications through having to redo the process.
Mapping is focused on the act of aligning that data to datums and control points after the surveying process is completed but it also requires major attention to detail in aligning coordinate frames and origin points in order to avoid baking in any errors that lead to mistakes being made once the map data is handed over to a customer

The problem is that if the surveying process wasn’t accurate, the mapping process will not have a solid foundation in the raw data to deliver accurate maps, so they are inherently tied to each other.

Trimble
Surveyors today have many tools in their toolbox, giving them flexibility across surveying and mapping applications. There are many highly accurate, easy-to-operate data capture systems to choose from these days, but challenges grow when combining and analyzing vast amounts of data from different sensors in the office to provide final deliverables. This has made field-to-finish software that delivers technological integration, workflow optimization and adaptability essential for the job.

Mapping projects often require less accuracy, but a lot of advanced survey technology is entering the mapping domain (e.g., mobile mapping and laser scanning) because of easier field operations and increasing understanding of the value of rich data to asset management.
