Septentrio AsteRx-i3 S Pro+ GNSS/INS Receiver: Meteorological Unmanned Surface Vessels (USV)
Boasting a split IMU design, this receiver can be flexibly deployed at key motion points of the hull, directly and accurately sensing true attitude even in rough sea conditions. Combined with centimeter-level RTK positioning, dual-antenna heading, and AIM+ anti-jamming technology, it provides stable and reliable navigation and time reference for USVs in complex marine environments. This ensures the collected meteorological data is tagged with precise spatiotemporal information, enhancing the scientific value of marine monitoring.
