Starting from the development of specialized components, SAPHYRION has successfully entered the market of specific embodiments of GNSS-based systems, which exploit the availability of GNSS signal processing solutions ahead of the current technology. In particular, SAPHYRION has pioneered the area of low-cost dual frequency GNSS receivers, which can effectively support the diffusion of GNSS water vapour sounding as an advanced tool for meteorology models refinement, and make possible the measurements of displacements in landslides and civil structures with millimeter precision.
