  • Is Russia behind new GPS interference in Bulgaria?

    Is Russia behind new GPS interference in Bulgaria?

    On Dec. 12, 2024, the European Union decided to include Bulgaria and Romania in the Schengen visa-free zone. On the same day, Bulgaria’s capital, Sofia, began experiencing interference with GPS signals. The interference, as reflected in aviation ADS-B systems and reported on GPSJam.org, continued through the new year and is ongoing as of this writing. 

    While these two events may be entirely unrelated, Vladimir Putin has a history of using GPS jamming and spoofing to show his displeasure with his neighbors growing closer to the West.

    • On Dec. 15, 2023, Poland activated a U.S. Aegis anti-missile system near its border with Kaliningrad, Russia. On the same day, Russia began jamming and spoofing GPS signals in northern Poland and parts of the Baltic. That interference persists to this day.

    The interference in Sofia may be contributing to a prolonged Bulgarian political crisis. Politicians there have been struggling to form a new government since elections in October. Dec. 10 saw the beginning of a new attempt. Interference with GPS can undermine overall confidence in government systems and institutions — another of Putin’s goals for neighbors with whom he is displeased.

    Another, though less likely, impact may be on Bulgaria’s electrical service. On Dec. 25, 2024, 20,000 households in western Bulgaria (Sofia is in the far west) lost electrical power and the outage continued for days. Many grid operators use GPS timing to help manage their systems. While press reports put the outages down to heavy snow and fallen trees, increased difficulty managing the grid might also be a factor.

    Bulgaria’s GPS interference appears to be coming from somewhere in Sofia, not from Russian territory, as is the case in the Baltic. Yet Russia may still be involved, at least in a supporting role.

    On Dec. 11, the news outlet Balken Insight reported on five Bulgarians being tried by the United Kingdom as Russian spies. It also said the Bulgarian interim prime minister was being urged to investigate alleged links between the case and top officials in Sofia.

  • NGS plans to release components of the modernized NSRS in 2025

    NGS plans to release components of the modernized NSRS in 2025

    Well, it’s January 2025 and it’s almost here — that is, the release of the beta version of the new, modernized National Spatial Reference System (NSRS) – NATRF2022, PATRF2022, CATRF2022, MATRF2022 and NAPGD2022.

    This newsletter will highlight some activities associated with the new NSRS. That said, this is short notice, but I would like to highlight that there is a webinar and workshop that will address the new NSRS scheduled for Jan. 9, 2025 — TRB workshop, “Navigating the Modernized National Spatial Reference System: A Geospatial Odyssey” and NGS webinar “Updates to Products and Models within the North American-Pacific Geopotential Datum of 2022.” I will provide more details on this later in the newsletter.

    First, on Oct. 9, 2024, NGS published a Federal Register that updated an implementation timeline for the modernized NSRS.

    Photo: NGS website

    The modernization of the NSRS is scheduled to occur in 2025 or 2026. NGS intends to release associated tools and services within five years of the modernization. The following details from the Federal Register outline the process for the rollout of the modernized NSRS:

    • NGS plans to roll out components of the modernized NSRS in 2025 or 2026. As each component is released at beta.ngs.noaa.gov, it can be publicly tested with feedback provided to NGS. The testing will continue for at least six months after the final component is released on beta.ngs.noaa.gov.
    • While the modernized NSRS is being rolled out and tested, the current NSRS will remain the official NSRS of the United States. The official NSRS (i.e., currently NAD 83, NAVD 88, etc.) may be found at geodesy.noaa.gov. Only one major improvement to the current NSRS is expected during this time: ITRF2020 will be integrated in all products and services.
    • Once testing is complete and all modernized NSRS components appear to be stable and correct, the Federal Geodetic Control Subcommittee (FGCS) will be asked to vote to approve the modernized NSRS (likely in 2026). If FGCS approves the modernized NSRS, NGS will publish an FRN announcing the approval of the modernized NSRS and begin a several-month process of transitioning all modernized NSRS components to the official website at geodesy.noaa.gov. During this transition, the beta website may be wiped of submitted data and no further submissions to the NGS IDB (the repository for the current NSRS) will be allowed.

    What does “Only one major improvement to the current NSRS is expected during this time: ITRF2020 will be integrated in all products and services” mean? I understand that one product that ITRF 2020 will be integrated into is the NOAA CORS Network (NCN). The CORS coordinates and velocities will be updated with ITRF 2020 values. That said, NGS datasheets will still provide coordinates in NAD 83 (2011), epoch 2010.0.

    As I’ve mentioned in previous newsletters, time really is running out and users need to obtain a working knowledge of the new, modernized National Spatial Reference System. For those attending the 104th TRB Annual Meeting on Jan. 5-9, 2025, in Washington, D.C., there is a scheduled workshop on the modernized NSRS. The workshop is sponsored by TRB Geospatial Data Acquisition Technologies Committee (AKD70). The workshop, titled “Navigating the Modernized National Spatial Reference System: A Geospatial Odyssey,” will be held on Thursday, Jan. 9, 2025, from 9:00 am to noon, in room 202B in the Convention Center in Washington, D.C.


    Navigating the Modernized National Spatial Reference System: A Geospatial Odyssey

    Thurs., Jan. 9, 2025
    9:00 am to 12:00 pm
    Room 202B, Convention Center
    Washington, D.C.

    This workshop will cover the following topics: 

    • Why the NSRS is being updated
    • The key goals of the modernization effort
    • Timeline, standards and technology considerations
    • The Geospatial Data Act of 2018 and its impact
    • There will be a discussion about the replacement of the North American Datum of 1983 and vertical datums and implications for existing workflows
    • There will also be a discussion about use cases and practical scenarios, how to transition and how to leverage new technology and tools.

    For those interested in more information on the TRB AKD70 committee, my August 2024 GPS World Newsletter highlighted activities associated with the Transportation Research Board’s ADK70 Standing Committee on Geospatial Data Acquisition Technologies.

    Since the new NSRS will be introduced this year, it is time for users of the NSRS to get familiar with the NOAA Technical Memorandum NOS NGS 92 document titled “Classifications, Standards and Specifications for GNSS Geodetic Control Surveys using OPUS Projects” written by  Dave Zenk and Dan Gillins, Ph.D., National Geodetic Survey, published on Oct. 23, 2024. This document provides the specifications users must adhere to when submitting GNSS projects to NGS for review and publication.

    Photo: NGS website

    The section below explains the purpose of the document. There are a few items that I have highlighted in the preface that users should be aware of:

    • The document replaces NOAA Technical Memorandum NOS NGS 58 and NOAA Technical Memorandum NOS NGS 59
    • Users will need to follow these specifications for all projects that will be submitted to NGS using OPUS Projects for review and publication
    • It is specifically limited to supporting NGS’s OPUS Projects Web-Based Tool.

    Preface

    This publication supplements Standards and Specifications for Geodetic Control Networks issued in September 1984 (Bossler 1984).

    This publication replaces NOAA Technical Memorandum NOS NGS 58 Guidelines for Establishing GPS-Derived Ellipsoid Heights (Standards: 2 cm and 5 cm), Version 4.3 (Zilkoski et al. 1997) and also replaces NOAA Technical Memorandum NOS NGS 59 Guidelines for Establishing GPS-Derived Orthometric Heights (Zilkoski et al. 2008).

    This publication provides classification, standards, and specifications for GNSS geodetic control surveys that use Global Navigation Satellite Systems (GNSS)which will be submitted to NGS using OPUS Projects for review and publication. These types of surveys were not well-established by the dates of the 1984, 1997, and 2008 publications, nor did OPUS Projects exist. In addition, since 2008 GNSS technology has improved and considerable research has been done into the best practices regarding these surveys and the analyses of achievable results (e.g., Allahyari et al. 2018; El Shouny and Miky 2019; Gillins and Eddy 2015, 2017; Gillins et al. 2019a; Gillins et al. 2019b; Jamieson and Gillins 2018; Park et al. 2018; Schenewerk et al. 2016; Soler and Wang 2016; Wang and Soler 2013; Wang et al. 2017; Weaver et al. 2018). That research supports this publication.

    This publication is specifically limited to supporting OPUS Projects (version 5.x), the current North American Datum of 1983 (NAD 83), the North American Vertical Datum of 1988 (NAVD 88) and other current vertical datums that are officially recognized by NGS. Future versions of OPUS Projects and future datums will require revision of this publication.


    For those that want to know more about the document, the National Geodetic Survey (NGS) held a webinar that described the classifications, accuracy standards and general specifications for GNSS geodetic control surveys using OPUS Projects on April 13, 2023. The webinar provided a summary of the NOAA Technical Memorandum NOS NGS 92 document. NGS presentations and webinars can be downloaded at the following websites: https://geodesy.noaa.gov/web/science_edu/presentations_library/, https://geodesy.noaa.gov/web/science_edu/webinar_series/2023-webinars.shtml, and https://geodesy.noaa.gov/web/science_edu/webinar_series/standards-specs-opus-projects.shtml.

    I highlighted some important sections of the April 2023 webinar in my May 2023 newsletter. Future newsletters will address the specifications in more detail, but I would encourage readers to download the NGS 92 document and the April 13 webinar and slides.

    On Dec. 18, 2024, NGS sent an email to individuals on NGS’s listserv informing them that they have made several updates to the NAPGD2022 products and that these updates are now available on the NGS alpha site.

    NGS Dec. 18 newsletter. (Photo: NGS website)

    To explain the product updates, NGS has scheduled a webinar for Jan. 9, 2025, to discuss the North American-Pacific Geopotential Datum of 2022 (NAPGD2022).

    I highlighted the NGS Alpha site and GEOID2022 — a product of the NAPGD2022 — in my July 2024 newsletter. I did a 4-part series in my GPS World newsletters in 2017 on the products of NAPGD2022 (June 2017, August 2017, October 2017, and December 2017). I would encourage everyone to register for the webinar.

    As previously stated in my newsletters, users should obtain a working knowledge of the new, modernized National Spatial Reference System. NGS publicly given presentations that have been collected for public viewing can be downloaded here.

    I would like to wish everyone a Happy New Year and a year filled with exciting opportunities.

    Photo: fatido / istock / getty images / getty images plus

    As we approach the holidays and if I get tired of writing about weighty scientific, technical and policy issues, I might apply for a copywriting position at Hallmark Cards. But for now we begin to think concretely about the coming year. In fact, due to our production timelines, as you are reading this issue we are busy completing the January one. So, what can you expect to see in these pages in 2025?

    First, more of the same… excellent content. Our cover stories will continue to bring you case studies from key GNSS application areas based on interviews with equipment manufacturers and end users. Our secondary features will cover bathymetric surveying; GNSS/PNT applications for consumers, science and business; autonomous vehicles; and indoor mapping. Our System of Systems section will continue to keep you informed about developments in GNSS, other PNT, and space exploration around the world. Our guest columnists — including Lisa Dyer of the GPS Innovation Alliance and Dana Goward of the Resilient Navigation and Timing Foundation — will continue to bring you their valuable perspectives. Our annual Directions section will continue to provide updates on all four GNSS and the regional constellations.

    Launchpad will continue to showcase the latest product releases and Market Watch will continue to bring you a roundup of timely industry news. Our buyers guides will continue to provide a handy reference to who makes what.

    Validated in real-world operations, the FOG INS integrated into the Boxer CRV, an armored 8×8 vehicle, offers enhanced troop safety, security and protection, coupled with high levels of firepower and mobility for sustained operations ranging from peacekeeping to high-intensity combat. The Boxer CRV is equipped with a reconnaissance mission module, including the two-person digital Lance turret, the first crewed medium-caliber turret to be put into service on the Boxer platform.

    This partnership between Rheinmetall and Advanced Navigation aligns with the objectives of the Australian Defense Global Supply Chain (GSC) Program, aimed at expanding opportunities for Australian suppliers and boosting export prospects within the global defense industry.

  • New services and capabilities for Galileo

    New services and capabilities for Galileo

    Galileo is Europe’s civil global navigation satellite constellation and a major success of the European Union (EU). It provides the world’s most precise satellite navigation performance. Galileo services began in December 2016 and are currently supplied to more than 3 billion users. They offer several high-performance services worldwide, featuring various levels of accuracy, robustness, authentication and security.

    Galileo is a key component of mass-market applications for such areas as transport, agriculture and timing but also for security-critical applications, such as health services, emergency and rescue services and law enforcement. Galileo services continue to expand with many new capabilities that are unique with respect to other GNSS. 

    The European Union Agency for the Space Programme (EUSPA) and the European Space Agency (ESA) continue to collaborate effectively on the many developments, deployments and evolution activities of the Galileo Programme, each according to their respective responsibilities for exploitation and system development, with the European Commission acting as the program manager.

    Stable Service Performance

    Galileo services continue to deliver excellent performance every month in a safe, secured and seamless manner, managed by EUSPA. The performance parameters of the Galileo services are independently monitored by the Galileo Reference Centre (GRC) and are regularly published on the web portal of the GNSS Service Centre (GSC): gsc-europa.eu. 

    The performance of the Open Service (OS) remains “Best in Class” among the GNSS providers. Timing users also continue to receive accurate (in the order of 5 ns) access to Galileo System Time, which they can trace to Universal Coordinated Time (UTC) through the corresponding offset parameters transmitted by the satellites.

    The Search and Rescue (SAR) service was delivered well beyond the commitment to the users, for both forward and return link services, while the High Accuracy Service (HAS) and the Public Regulated Service (PRS) continue being provided as planned in the corresponding Service Definition Document (SDD).
