About

Yannick Breva is a specialist in high-precision Global Navigation Satellite Systems (GNSS), with a focus on antenna calibration and signal processing. His research centers on the critical role of phase center corrections—both offsets and variations—in achieving the sub-centimeter accuracy required for modern geospatial applications, including terrestrial reference frame establishment and land and water management. Breva’s most cited work, "Multi-GNSS Receiver Antenna Calibration" (2020, 3 citations), addresses the growing need for standardized calibration across multiple satellite constellations. His follow-up study, "Phase Center Corrections for new GNSS-Signals" (2019, 2 citations), extends this work by highlighting the current limitations of the Antenna Exchange Format (ANTEX), which only provides corrections for legacy L1 and L2 frequencies of GPS and GLONASS. By advocating for the inclusion of new signals (e.g., L5, E5a), Breva’s contributions are directly shaping the future of GNSS infrastructure, ensuring that emerging multi-frequency receivers can deliver the reliability demanded by precision agriculture, geodesy, and autonomous systems.
