High-precision positioning is a fundamental requirement across a wide range of industries, including autonomous navigation, precision agriculture, geospatial surveying, offshore exploration, and industrial automation. As global industries increasingly rely on precise location data, the need for a flexible, high-accuracy GNSS correction solution has never been greater. However, existing high-precision positioning services face significant limitations, including hardware lock-in, a dependency on dense reference networks, and longer convergence times. TruePoint | REACH is a next-generation Precise Point Positioning with Ambiguity Resolution (PPP-AR) correction service that addresses these challenges by offering global, centimeter-level accuracy with unparalleled flexibility and reliability, on both land and sea.
A standout feature of TruePoint | REACH is its hardware-agnostic architecture. Many of today’s high-precision GNSS correction services are designed to work exclusively with proprietary receivers, limiting user flexibility and increasing costs. TruePoint | REACH, however, is built to be fully compatible with third-party multi-frequency GNSS receivers, making it accessible to a much wider range of users and industries. To support seamless integration across different hardware platforms, TruePoint | REACH adheres to open standard SSR correction formats, including RTCM v3 and 3GPP LPP, ensuring interoperability across both GNSS positioning systems and modern telecom infrastructures. This capability allows TruePoint | REACH to function as a primary or complementary correction source, providing greater redundancy and improved positioning resilience. Further, a light-weight position engine library is available along with the service for seamless and easier integration with 3rd party hardware platforms.
Unlike traditional PPP solutions that often require lengthy convergence periods, TruePoint | REACH enhances positioning accuracy and reduces convergence time through integer ambiguity resolution by leveraging high-quality Orbit, Clock, and Biases (OCB) corrections. While many conventional PPP solutions require upwards of 15 minutes or longer to reach a precise fix, TruePoint | REACH enables multi-frequency receivers to estimate ionospheric delays independently, achieving a fixed solution with horizontal position accuracy better than 3 cm in less than 10 minutes, and in many cases, within 5 minutes. This rapid convergence time significantly expands the use cases for high-precision GNSS applications, making it suitable for real-time operations across industries.
Reliability is a key differentiator for TruePoint | REACH. With a 99.9% SLA, the system ensures uninterrupted high-precision positioning, even in the most demanding operational environments. This level of reliability makes it a critical solution for applications where a longer downtime is unacceptable. Additionally, TruePoint | REACH excels in regions lacking dense reference networks, including the open ocean, Latin America, the Middle East & Africa and other isolated regions. In these areas, conventional high precision solutions such as NRTK are often impractical or unavailable, making TruePoint | REACH a vital alternative.
This presentation will provide a comprehensive analysis featuring test results with the service integrated to multiple vendors’ GNSS receivers and hardware platforms across the globe demonstrating the service’s accuracy, convergence performance and operational reliability. The tests are run over several days at multiple locations across the globe with repeated resets for obtaining statistical position accuracy and convergence time metrics. Data collected from various global field tests will illustrate the capabilities of TruePoint | REACH in diverse environmental and operational conditions. The tests are performed with observations from multi-frequency receivers over standard interfaces (e.g., serial RTCM, NTRIP) and the service over internet connected to a mini-computer running platform independent PPP-AR position engine. Additionally, the tests will include performance results with a multi-frequency high precision GNSS chip supporting the TruePoint | REACH service.
Additionally, the presentation will cover the fundamentals of the TruePoint | REACH algorithm, explaining how its PPP-AR approach enables faster ambiguity resolution and improved accuracy. Key differentiations between TruePoint | REACH and conventional PPP based solutions will also be highlighted, providing a deeper understanding of how this technology enhances performance while remaining fully hardware agnostic.
By offering centimeter-level accuracy, rapid convergence, global coverage, and hardware compatibility, TruePoint | REACH represents an advancement in GNSS correction services. It unlocks new possibilities for a wide range of applications, including precision farming, offshore positioning, geospatial surveying, and industrial automation. As demand for high-precision GNSS solutions continues to rise, TruePoint | REACH is poised to become a cornerstone technology in the evolution of global positioning.
