In the rapidly evolving field of precision, satellite-based navigation, GMV GSharp is a commercially deployable high-accuracy GNSS solution providing safe, real-time corrections and file-based GNSS products with minimal latency and variable sampling rate, length and update rate.
Speaking to Inside GNSS at this year’s InterGeo in Frankfurt, Laura Martínez Fernández, GMV’s High Accuracy Services Manager underscored the system’s aspiration to go beyond niche professional domains into automotive, robotics and off-road applications: “We see GSharp as the bridge between raw GNSS capability and truly safe, mass-market, critical positioning.”
From the outset, GMV has designed GSharp as a reliable solution for multiple markets, with an architecture comprising three core pillars: the safe correction service (SCS), the safe positioning engine (SPE) and the global GNSS station network (GGSN).
“Our aim is to deliver integrity and convergence time performance that make sub-decimeter accuracy not just a lab benchmark but a mainstream reality,” Martínez Fernández said. GSharp’s performance specs are indeed ambitious: horizontal accuracy better than 3 cm (95%), convergence times under 30 seconds in nominal conditions, integrity risk below 10⁻⁷/h and service availability above 99.9 %.
Sensor-fusion capabilities also feature prominently, with the SPE accepting raw GNSS plus IMU, wheel-tick and other vehicle sensors, tailored for challenging environments and safety-critical use cases.
Bringing experience to bear
Readers will know GMV’s leadership extends into the Galileo ecosystem. The Galileo high-accuracy service (HAS), officially operational since January 2023, provides free, globally accessible real-time high-accuracy corrections via the E6-B signal and internet links. GMV developed the core high-accuracy data generator (HADG) infrastructure underpinning that service.
Martínez Fernández said, “Our work on Galileo HAS has given us the experience that we put directly into GSharp. This is about high accuracy, like what we helped to achieve with HAS, but it’s also about delivering assured positioning under real-world conditions.”
To be clear, GSharp users get guaranteed, safety-qualified centimeter-level positioning with integrity monitoring, fast convergence, and service-level support – capabilities that go well beyond the open, best-effort performance of Galileo HAS.
GMV GSharp embodies the convergence of high-accuracy GNSS corrections, safety-critical integrity, and mass-market readiness. In line with the broader trends we observed at this year’s InterGEO, the offering underscores the shift from centimeter-level capability being the privilege of specialized users, to the baseline expectation across industries, unlocking reliable, centimeter-class positioning for everyone.
