Developed by the European Union, Galileo is an independent, global, satellite-based navigation system that provides a range of services. Among its most significant advancements is the Galileo High Accuracy Service (HAS), which aims to offer free, high-precision positioning to users worldwide. This article explores Galileo HAS, covering its history, architecture, implementation phases, performance, limitations, and future prospects.
What is the Galileo High Accuracy Service?
Galileo HASis a precision augmentation service leveraging precise point positioning (PPP) to provide corrections to GNSS signals, aiming at a positioning accuracy of less than 20 cm horizontally and 40 cm vertically. Unlike the traditional real-time kinematic (RTK) method, which depends on local reference stations, HASdelivers corrections globally via Galileo satellites using the E6-B signal, as well as over the Internet. The service provides corrections for measurements on multiple frequencies across both Galileo and GPS constellations, enhancing real-time positioning performance.
The concept of a high-accuracy service for Galileo was driven by growing demand for decimeter-level accuracy in applications such as precision agriculture and autonomous vehicles. Initially envisioned as a paid service under the Galileo Commercial Service, feasibility studies in 2014 confirmed its potential. In 2018, the European Commission decided to offer HASfree of charge.
In the Galileo HASspecifications, two Service Levels are defined. Service Level 1 with global availability and the enhanced Service Level 2 for the European Coverage Area. The Galileo HASroadmap consists of three phases: Phase 0 (testing and experimentation), Phase 1 (Initial Service), and Phase 2 (Full Service). After extensive internal testing, Phase 1 was officially launched in January 2023, marking a significant milestone in Galileo’s evolution as a leading GNSS provider. Phase 2 is currently in development and expected to launch in the near future.
Technical Components
Galileo HASis designed with several key components that enable its high-precision capabilities. One of the most critical aspects involves orbit and clock corrections. These corrections compensate for inaccuracies in satellite orbital positions and clock errors, which are major sources of positioning errors in standard GNSS. Another essential element of HAS is the provision of signal bias corrections to enable precise carrier phase ambiguity resolution, which in turn greatly improves positioning accuracy. In the current Initial Service (Phase 1), Service Level 1provides only code bias corrections, along with orbit and clock corrections. In Phase 2, Service Level 1 will be upgraded to include both code and phase bias corrections, while Service Level 2will further add atmospheric (ionospheric and tropospheric) corrections for the European Coverage Area.
Capable GNSS receivers decode the high-accuracy corrections broadcast on the E6-B channel for Galileo (E1, E5a, E5b, E5, AltBOC, E6) and GPS (L1, L2, L5) signals and apply them via algorithms to enhance positioning solutions. This refines raw measurements to reduce errors, providing decimeter-level accuracy for use in fields rangiranging from ecological surveys to city infrastructure management and routine mapping tasks.
In addition to satellite broadcasts, the corrections are also made available over the Internet via the NTRIP protocol, providing an alternative access method for users with network connectivity. Notably, receiving HAS corrections via NTRIP eliminates the need for a receiver with E6-B capability, but the receiver still needs to implement the PPP algorithm to process the corrections.
Architecture
The Galileo HASrelies on the robust infrastructure already established within the Galileo system. At the foundation of this network are the Galileo Sensor Stations (GSS), a global network of 15 monitoring stations (according to the latest updates). These stations play a vital role by continuously collecting GNSS measurements, which serve as the raw data needed to generate precise corrections. The collected data are then processed by the High Accuracy Data Generator (HADG). This system analyzes the GSSinput and produces high-precision corrections for both Galileo and GPS signals. Once the corrections are prepared, they are transferred to Uplink Stations (ULS), which transmit the correction data to the Galileo satellites for distribution via Signal-in-Space, or to an NTRIP caster for distribution over the Internet. In the case of Signal-in-Space distribution, the Galileo satellites themselves serve as the delivery mechanism to users worldwide, broadcasting the corrections globally via the E6-B signal.
The HAS is being rolled out in three phases, ensuring progressive development and refinement:
Phase 0 (2020–2022): Internal Testing
Focused on validating the feasibility of broadcasting HAS corrections via the E6-B signal.
Tests involved internal and external stakeholders, with feedback used to refine the service.
Phase 1 (January 2023–Present): Initial Service
Declared operational on January 24, 2023, Phase 1 provides Service Level 1 with global coverage, though with reduced performance compared with the enhanced Service Level 1 expected in Full Service (Phase 2).
Current corrections include orbits, clocks, and code biases.
The service area excludes certain regions (e.g., parts of the Pacific and Australia) because of infrastructure limitations.
Convergence time is specified as <300 seconds (Service Level 1) or <100 second (Service Level 2), with horizontal accuracy <20 cm and vertical accuracy <40 cm under optimal conditions. Currently, accuracy <20 cm may be achieved with a convergence time up to 60 minutes, owing to the lack of phase bias and atmospheric corrections.
Phase 2 (Future): Full Operational Capability
Will provide full Service Level 1 performance globally with horizontal accuracy <20 cm and vertical accuracy <40 cm, adding phase bias corrections for faster convergence <300 seconds.
Will introduce Service Level 2 for regional coverage in Europe with horizontal accuracy <20 cm and vertical accuracy <40 cm, adding phase bias and atmospheric corrections for faster convergence (<100 seconds).
Will include data authentication and enhanced infrastructure for improved reliability and coverage.
Challenges and Limitations
The current capabilities of Galileo HASare constrained by several limitations, which are expected to diminish as the system evolves. Global coverage is not yet fully established, with parts of the Pacific region and Australia remaining outside the service area. While users can receive HAScorrections anywhere in the world, the official performance specifications apply only within the service boundaries. However, even within the service area, achieving the specified accuracy presently requires long convergence times, limiting applicability in scenarios that demand rapid solutions. Convergence time is expected to decrease significantly in Phase 2, when phase bias and atmospheric corrections are introduced.
As of 2025, relatively few commercial receivers support HAScorrections via E6-B, with availability concentrated in professional and industrial receivers. The lack of integration into mass-market devices limits broader adoption, reflecting both the technology’s ongoing development and the additional hardware complexity required to receive HAScorrections.
Finally, while decimeter-level corrections are sufficient for a wide range of applications, many professional domains, such as surveying, demand cm-level accuracy. Even at Full Service, HASwill not provide this level of precision, meaning that certain fields will continue to rely on RTK. However, considering that most RTK vendors require a paid subscription or charge per hour, HAScan still provide great value to surveyors and other professionals through its use in preliminary work or applications where cm-level accuracy is not critical, offering decent accuracy free of charge.
The Galileo constellation was recently reinforced with satellites 31 and 32, which became operational in January 2025, while the ground segment underwent major upgrades in 2024. Despite these improvements, Phase 1 (Initial Service)remains the only operational HAS capability. As of September 2025, Phase 2remains in active development. In January 2025, it was announced that the European Union Agency for the Space Programme (EUSPA) awarded GMV a 45-month, €12 million contract to develop an enhanced HADGthat will support enhanced Service Level 1 globally and Service Level 2 for Europe. The contract’s duration provides an indication of the anticipated timeline for completion.
An inquiry regarding the timeline for Galileo HASService Level 2 (Phase 2) was submitted to the European GNSS Service Centre (GSC) Helpdesk. Their reply stated that the schedule is not available at this time and will be announced through GSC channels once released.
Wider adoption is anticipated as more GNSS receivers capable of receiving and decoding the E6-B signal to process HAScorrections become available, enabling sectors such as autonomous transportation, fleet management, and smart agriculture to capitalize on improved performance. Adoption is also expected to accelerate when Galileo HAS reaches Full Operational Capability with the launch of Phase 2, which will reduce convergence times and broaden the system’s applicability.
Ultimately, Galileo HASis positioned to become a cornerstone of high-accuracy GNSS, democratizing access to professional-grade precision.
The development of an Integrated Real-Time Precise Point Positioning (InRPPP) system leveraging BeiDou Navigation Satellite System (BDS) B2b, B2a, and B1C services has significantly enhanced satellite-based positioning accuracy.
By resiliently utilizing these augmentation messages, the InRPPP system corrects satellite orbit and clock errors and mitigates ionospheric delays, outperforming traditional methods. Experimental results from both static and kinematic conditions demonstrate superior performance, showing improved positioning accuracy, faster convergence times, and greater stability in challenging environments. This breakthrough offers potential for applications in real-time navigation, precision positioning, and disaster monitoring, with a broader impact on industries requiring reliable and continuous positioning data.
The implications of the InRPPP system are vast, with applications spanning multiple sectors that depend on high-precision satellite navigation.
Satellite-based navigation systems, like the Real-Time Precise Point Positioning (RTPPP), are crucial for many industries that require accurate location data. However, these systems face limitations in areas with weak Internet connectivity or signal interference. BeiDou’s satellite augmentation services, namely B2b, B2a, and B1C, have emerged as a promising solution.
Yet, integrating these services into one cohesive system for optimal performance remained unexplored. This study pioneers the Integrated InRPPP system, which integrates all three services including correcting satellite clock, orbit errors, and ionospheric delays, unlocking new levels of positioning accuracy. The results from this research address critical limitations in current satellite-based positioning technology, setting the stage for real-world applications in complex environments.
In a 2025 Satellite Navigation publication (DOI: 10.1186/s43020-025-00172-x), researchers from the State Key Laboratory of Geo-Information Engineering and Key Laboratory of Surveying and Mapping Science and Geospatial Information Technology of MNR, State Key Laboratory of Spatial Datum, and Hohai University introduced the InRPPP system, a new approach that leverages the B2b, B2a, and B1C services of the BDS.

By combining these services, the InRPPP system corrects satellite orbit and clock errors while mitigating ionospheric delays. With enhanced accuracy, stability, and faster convergence times, this system has the potential to transform satellite-based positioning, offering more reliable and continuous service in real-time applications, especially in environments where traditional positioning systems struggle to perform.
The InRPPP system brings a new level of precision to satellite navigation by combining the best of BeiDou’s B2b, B2a, and B1C services. Through this integration, the system corrects satellite orbit and clock errors with B2b and B2a services, while B1C handles ionospheric delays. This resilient approach allows the system to deliver superior performance, even in high-occlusion or remote environments. The static experiments showed the InRPPP system surpasses other methods, with a 59.6% improvement in positioning accuracy and a 65.9% reduction in convergence time compared to using B2b, B2a, or B1C individually.
In dynamic conditions, the system demonstrated enhanced stability and reduced signal interruptions, achieving up to a 34.3% improvement in accuracy. The integration of these services increases the number of visible satellites, enhancing the Position Dilution of Precision (PDOP) values and ensuring better satellite geometry. This integrated approach not only improves accuracy but also ensures continuous, reliable solutions, making it a game-changer for fields like geodesy, navigation, and disaster monitoring.
Academician Yuanxi Yang of the Chinese Academy of Sciences, the lead researcher behind the InRPPP system, remarked, “The ability to integrate multiple BeiDou augmentation services into a single real-time positioning system represents a major breakthrough. By leveraging B2b, B2a, and B1C, our system offers a more reliable and accurate solution than anything available today. In both static and kinematic tests, the InRPPP system has outperformed traditional positioning methods, demonstrating its robustness and resilience in environments where signal conditions are far from ideal. This system is already applied in real applications and has potential to reshape industries reliant on satellite navigation and positioning.”
The implications of the InRPPP system are vast, with applications spanning multiple sectors that depend on high-precision satellite navigation. From autonomous vehicles and precision agriculture to disaster management and geospatial services, the enhanced accuracy and stability offered by InRPPP can support real-time decision-making in critical environments. This system also promises to improve the resilience of navigation systems in regions with poor satellite visibility or signal interference. As technology advances, the InRPPP system could pave the way for even more robust solutions, advancing global sustainability goals and improving disaster response capabilities by offering uninterrupted, reliable positioning data.

Mayflower Communications Company, a Massachusetts-based leader in advanced anti-jam system solutions for military and commercial markets, has been granted two U.S. patents — US 11,262,457 and US 12,235,365 — that significantly advance its GNSS anti-jam capabilities.
The patents expand Mayflower’s proprietary technology into signals of opportunity (SoOP), enabling interference suppression across both Iridium and GNSS frequency bands.
GPS remains a cornerstone of positioning, navigation and timing (PNT) for both military and commercial platforms. However, its vulnerability to intentional and unintentional jamming and spoofing has underscored the need for more resilient PNT solutions. Signals of opportunity — non-navigational RF signals not originally intended for PNT — can serve as valuable backups when GPS signals are degraded or denied. But like GPS, these signals are also susceptible to interference and require protection to be viable contributors to a resilient PNT framework.
Mayflower’s newly patented technology provides simultaneous protection of GPS and Iridium satellite signals within a compact, low size, weight and power (SWaP) footprint — critical for modern platforms operating in GPS-contested environments.
“The issuance of these seminal patents by the U.S. Patent and Trademark Office affirms Mayflower’s continued leadership in resilient PNT technologies for both military and commercial markets,” said Triveni Upadhyay, president of Mayflower. “Our innovative approach to filtering interference across multiple satellite communication systems — including Iridium — demonstrates our ability to meet the growing demand for GPS-alternative solutions. Leveraging signals of opportunity without significantly increasing SWaP is a key milestone in delivering more robust, operationally viable PNT systems. We’re excited to bring this technology to our partners across sectors.”
