The construction of the Perca Bypass, a critical infrastructure project underway in the Italian Alps, highlights the increasing role of advanced technology in managing complex builds. Located near the village and commune of Perca — a destination known for its tourism trade — the new 632 m tunnel and supporting road network are designed to improve regional connectivity and enhance commuter safety.
The project, which began in 2023 and is expected to take three years to complete, is being delivered through a joint venture between European construction group Strabag and regional specialist Alpenbau. Once finished, the bypass is expected to relieve the flow of up to 26,000 vehicles that pass through Perca daily during peak periods, easing congestion and opening new routes for both tourism and local commerce.
Given the large number of machines, teams, and partners involved, coordinating the work requires effective management and communication tools. Alpenbau, drawing on a long-standing collaboration with Topcon Positioning Systems, the team is now using Topcon’s Aptix Integration Platform, which enables site managers to monitor and oversee progress remotely, offering real-time insights into workflow and project status without leaving their offices.
Acting with Aptix
“Aptix is a very convenient solution for us to manage our construction sites,” said Benjamin Niederkofler, CEO of Alpenbau. “One of the advantages of Aptix is that you can directly load 3D models onto machines that are equipped with machine control systems. This means that you always have the possibility to monitor the site from the office. This is a very important and fundamental tool for us to remotely monitor a construction site.”
Aptix consolidates data from different contractors and machinery, regardless of the manufacturer or operating system, and provides a comprehensive view of project performance. Senior leaders can access essential metrics in real time, such as work progress, fuel consumption, and carbon emissions, improving the ability to make informed decisions.
Control, Collaboration, Clarity
Throughout every stage — from planning and design to actual construction — the platform supports automatic workflows that deliver designs to machines and collect telematics data without manual intervention. This automation reduces the risk of missing information and helps maintain clear communication among stakeholders.
A joint effort of this scale requires constant collaboration among contractors, local authorities and other stakeholders. The Aptix platform helps facilitate transparency in workflows by allowing access to daily productivity reports and construction data, supporting open cooperation and oversight for both project managers and crew.
“Recently it has become increasingly important that we create transparency and co-operation on this construction site and share productivity daily with construction management or even with our customers,” said Niederkofler. “Having this transparency across the entire construction site is a decisive advantage.”
Andrea Marzi, technical director at Strabag Italy, added, “This unique platform allows all parties involved in the project to access all relevant construction information and data.”
Once completed, the Perca Bypass is expected to generate new economic opportunities for the region. Project leaders say that by adopting innovative digital workflows and centralized data management, they are able to direct complex operations more effectively and deliver the project with increased speed and accuracy.

One of the most persistent sources of GNSS error — ionospheric delay — has been challenging to correct in real time, especially for mass-market devices. While dual-frequency receivers and commercial correction services can mostly mitigate this issue, they remain too costly and impractical for the billions of smartphones and IoT devices that rely on single-frequency GNSS. Even for dual-frequency systems, the commonly used ionosphere-free linear combination amplifies multipath and receiver errors and reduces data redundancy — yielding only two usable combinations from four original measurements.
This landscape may be shifting with the introduction of GloTEC, a real-time global Total Electron Content (TEC) map from NOAA’s Space Weather Prediction Center (SWPC), released in February 2025. GloTEC assimilates both ground- and space-based observations to provide real-time global ionospheric corrections without relying on error-prone linear combinations.
Unlike coarse models such as the broadcast Klobuchar algorithm or forecast-only products such as the predicted IGS Global Ionosphere Maps, GloTEC updates every 10 minutes using real-time measurements. This high refresh rate establishes a new benchmark for open-access ionospheric nowcasting in GNSS applications.
Originally designed to monitor and mitigate space weather impacts on aviation and communications, GloTEC may also deliver a broader benefit: enabling precise, scalable GNSS corrections for low-cost, single-frequency devices, making high-accuracy positioning more accessible and democratic.
Why Nowcasting Matters for GNSS
The GNSS community has long had to choose between accuracy and latency. Predictive models, such as those from NASA CEDIS or CODETEC, can offer reasonable approximations but may fall short when real-time corrections are required, particularly in the context of navigation, asset tracking or autonomous systems.
Post-processed products (such as rapid/final IGS GIMs) provide excellent fidelity but are typically delayed by hours, days, or even weeks. This makes them useful for research or auditing, but not for real-time navigation needs.
Commercial correction services, such as Trimble RTX and Hexagon’s TerraStar, have filled the gap for high-value applications. These systems interpolate ionospheric corrections in real time, but at a significant cost and they typically require specialized GNSS receivers.
GloTEC bridges this gap by delivering a publicly accessible, high-refresh ionospheric product that can support near real-time corrections. Updated every 10 minutes with a 2.5° latitude and 5° longitude spatial resolution, GloTEC represents a major step forward for public sector GNSS capability, particularly in contexts where accuracy, reliability and scale are all crucial. The data has also been supporting the United States Space Force and is accessible through their Unified Data Library (UDL).
Technical Approach: Adapting GloTEC for Practical Use
While the potential of GloTEC is exciting, turning it into usable corrections for consumer-grade devices isn’t straightforward. TEC maps represent volumetric electron density, while most mass-market GNSS chipsets, especially in smartphones, expect simplified models, such as the eight-parameter Klobuchar model broadcast by GPS satellites. GloTEC is a three-dimensional data assimilation system that uses a Gauss-Markov Kalman Filter to estimate electron density in the ionosphere. It ingests slant TEC measurements from ground-based GNSS receivers and space-based radio occultation data, using the IRI-2016 model as its background state.
To bridge this mismatch, Zephr’s team has been exploring regional fitting techniques, whereby a local subset of GloTEC data is used to generate custom Klobuchar coefficients. These can be transmitted to devices via standardized protocols, such as the LTE Positioning Protocol (LPP), enabling improved ionospheric delay estimation with minimal changes to device-side computation. Even with a regionalized Klobuchar fit and LPP encoding, there is still the problem of accessing the GNSS chip to apply the corrections. To solve this problem, Zephr has created a virtualized positioning engine that takes the raw GNSS measurements from the chip and provides a purely software-based solver. This approach allows the team to implement a variety of more advanced positioning techniques using commodity hardware such as smartphones.
Field Testing: A Quantitative Step Forward
To evaluate the efficacy of GloTEC in improving GNSS accuracy, engineers at Zephr used the virtualized positioning engine to conduct 51 real-world campaigns across various conditions – including urban, suburban, static, walking, and driving – using a Pixel 8 smartphone and an RTK unit for ground truth.
The results were promising, as shown in Figure 1:
Figure 1: GloTEC vs. CODETEC vs. Android Native across multiple scenarios. (All figures provided by author)
We can break down these results using detailed graphs for each scenario as examples. This will provide a more in-depth look at the positioning for specific traces through the outlined scenarios in Figure 2, Figure 3 and Figure 4:
Figure 2: GloTEC vs. CODETEC vs. Android Native for an open sky walking scenario
Figure 3: GloTEC vs. CODETEC vs. Android Native for a suburban downtown walking scenario.Figure 4: GloTEC vs. CODETEC vs. Android Native for a mixed sky driving test.
Across all categories, the GloTEC-based regional fitting approach significantly outperformed both the default GNSS solution (which uses broadcast data plus a Klobuchar mode) and the competing IGS products. Accuracy improved by up to 69% in driving scenarios and 46% in walking scenarios, compared to standard smartphone GPS.
While the Pixel 8 used in testing supports dual-frequency GNSS, smartphones face several practical limitations that hinder effective use of ionosphere-free dual-frequency combinations. These include limited signal availability (due to antenna constraints, L1/L5 support gaps, and partial constellation coverage), elevated multipath and noise (especially from omnidirectional antennas in dynamic conditions), and unstable clock biases that complicate error modeling. In fact, iono-free combinations can amplify multipath effects, potentially degrading accuracy in some conditions.
Despite these constraints, the results show that meaningful improvements in positioning are possible using a software-based approach with publicly available corrections. GloTEC, when paired with cooperative or cloud-based GNSS engines, offers a substantial step forward without requiring expensive commercial correction services or specialized hardware.
Broader Implications and Next Steps
While these results are promising, several challenges remain before GloTEC-based corrections can be broadly deployed:
Connectivity Requirements: Real-time access to GloTEC requires periodic downloads over cellular or Wi-Fi connections, raising questions about reliability in low-bandwidth or disconnected environments.
Global Calibration: The accuracy of regional fitting depends on local coverage density and VTEC variability. Further tuning may be needed in equatorial or polar regions, where ionospheric behavior is more volatile.
Nevertheless, the availability of GloTEC marks a significant milestone. For the first time, a free, real-time, high-resolution ionospheric correction product is accessible to developers, researchers, and engineers seeking to improve GNSS accuracy at scale. NOAA SWPC has plans to integrate more low-latency space-based and ground-based data into GloTEC in the near future. The new version of the model outputs will be released to the public once the results are validated. As techniques for applying it to mobile and IoT devices mature, the GNSS community may see a broad shift toward more precise, resilient, and cost-effective positioning systems.
GloTEC may have been designed to help forecasters monitor the response of the ionosphere due to space weather events, but its potential to provide an advanced tool for positioning on Earth is just beginning to be understood. In a world where nearly every mobile application depends on location, and where the cost of poor accuracy is rising (from package delivery failures to navigation errors), this kind of public infrastructure is invaluable.
Researchers and industry developers alike should explore how this NOAA capability can be integrated into their positioning systems. If properly supported, GloTEC could become one of the most impactful GNSS innovations of the decade.

During the geomagnetic storm that took place May 10–11, 2024, GPS users reported significant positioning errors and outages. In particular, farmers in the Central United States reported difficulty in getting a fix with their tractors and other farm equipment.
Also affected, to a lesser extent, was the Southwestern United States.
A new study has identified the cause of the GPS outages by analyzing the data from a 1‐Hz GPS receiver network. Standalone GPS position errors In precise point positioning (PPP) mode in the Central United States reached 70 meters on May 10. The errors were attributed to a steep wall in ionospheric plasma that rapidly moved southward.
In the soutwestern states, the GPS position errors were elevated 10 to 20 meters because of the enhanced plasma density.
Vertical protection level as provided by WAAS.
Then, on May 11, intense auroral activity caused rapid enhancements in the ionospheric plasma, leading to abrupt position errors of 10 meters. Network‐based position systems likely encountered even longer duration of position errors because these ionospheric disturbances are localized.
“These findings highlight the need for more accurate understanding of ionospheric plasma conditions, as well as software and hardware improvements, to reduce disruptions during space weather events,” report the authors of “Spatio‐Temporal Evolution of Mid‐Latitude GPS Scintillation and Position Errors During the May 2024 Solar Storm.” Authors are Waqar Younas, Yukitoshi Nishimura , Weixuan Liao , Josh L. Semeter, Sebastijan Mrak, Jade Morton and Keith M. Groves. The full report will appear in an upcoming issue of the Journal of Geophysical Research: Space Physics and is now available on ResearchGate.

Key Points
PPP failed to converge in the SED and trough, while PPK became unstable after CME arrival until the recovery phase.
SED, EIA, and trough created position errors on the noon‐evening sector. Substorms caused position errors on the nightside.
Scintillation, cycle slips, satellite geometry and ray bending were identified as contributing factors to the large position errors.

The study investigates impacts of the May 2024 superstorm on the mid‐latitude GPS scintillation and position errors. Using 1‐Hz GPS receiver data, the research team identified position errors in PPP mode reaching up to 70 m in the Central United States during the storm main phase on May 10.
The PPK solution becomes unstable following the arrival of storm and lasted till the recovery phase, coinciding with reported GPS outages of farming equipment. The large position errors were attributed to strong scintillation and carrier phase cycle slips around the equator-ward boundary of the ionosphere trough, where large total electron content (TEC) gradients and irregularities were present.
In the Southwestern United States, position errors of 10–20 m were associated with the storm‐enhanced density and equatorial ionization anomaly. Scintillation and cycle slips in this region were minor, and bending of the GPS signal paths (refractive effect) is the probable cause of the position errors. PPP outages were also associated with sudden changes in the geometric distributions of available GPS satellites used in position calculations.
On May 11, energetic particle precipitation during substorms led to abrupt jumps in TEC and scintillation, resulting in rapidly evolving position errors of up to 10 m. These findings highlight the critical role of storm‐time plasma transport, precipitation and irregularity formation in degrading GPS performance.
“The study underscores the need for accurate ionospheric state specification, improved signal processing technique, real‐time ionospheric corrections, and optimized satellite selection algorithms to enhance navigation resilience during severe space weather events,” the authors conclude.

The iPhone connects to Topcon’s HiPer CR receiver, enabling the application to collect georeferenced images. The receiver and iPhone are mounted on a specialized handle designed and manufactured by Topcon so that users can capture point clouds without a tripod.
The CR-H1 can be used for utilities and subsurface mapping, construction verification and earthworks, civil engineering and site verification, land surveying and forensics and 3D data capture. Topnet Live subscriptions are available for the CR-H1, providing real-time GNSS corrections that deliver higher-quality point clouds.

Flyability has introduced a “Smart Return-to-Home” (RTH) feature for its Elios 3 UAV, designed to enhance its autonomous capabilities. This feature allows the UAV to return to its take-off point using the shortest available path while avoiding obstacles in real time.
During flight, Smart RTH monitors battery levels through a new flight management gauge, notifying the pilot when it is time to return. The feature is activated via Flyability’s Cockpit flight app, and pilots can take manual control at any point. By automating the return process, the system helps pilots focus on inspections without concerns about battery management or navigation in complex environments. Smart RTH uses lidar scans to generate a flight plan that the UAV executes independently.
The AirWarden Remote ID Receiver detects and decodes Remote ID signals broadcast by UAVs. It is designed for organizations and authorities that need to monitor UAV activity for safety, security and compliance with regulations.
It decodes the information transmitted by UAVs in accordance with FAA and other regulatory standards. The data it captures includes the UAV’s identification number, its precise location (latitude, longitude and altitude), the takeoff location, operator location if available, timestamps, and other relevant metadata.
The AirWarden can be deployed as a standalone unit or integrated into larger security and monitoring systems. Users interact with the system through a web-based or software interface that facilitates live monitoring, alert management, and data analysis.
Additionally, the AirWarden can integrate seamlessly with other security infrastructure, such as video surveillance and access control systems. This integration seeks to improve how security teams automate responses and coordinate actions when unauthorized or suspicious drone operations are identified.
