The AntaRx-Si3 GNSS/INS (Inertial Navigation System) receiver delivers centimeter-level positioning together with orientation (heading, pitch and roll angles) and dead-reckoning functionality. This combination of sensors enables the highest level of performance and reliability in the most challenging environments. AntaRx-Si3 smart antenna is designed to be strong inside and out. High impact resistance polycarbonate housing with IP69K sealing protects the receiver. On the inside, proprietary technology and advanced algorithms ensure robust tracking despite heavy vibrations or shocks.
