About XAir

XAir is an independent knowledge hub for GNSS/RTK high-precision positioning. We explain the technology — carrier-phase differential positioning, Network RTK, NTRIP, PPP-RTK and multi-constellation, multi-frequency receivers — and track how it is applied across surveying, UAVs, robotics, autonomous driving and precision agriculture.

What We Publish

• Technology deep dives — how RTK actually works, from ambiguity resolution to correction delivery.
• Application guides — how centimeter-level positioning is deployed in the field.
• Industry insights — analysis of the GNSS ecosystem, constellations and emerging trends such as the low-altitude economy and physical AI.

Editorial Independence
