The AntaRx-Si3 from Septentrio is a GNSS/INS Receiver designed to provide robust and reliable positioning and 3D altitude in challenging environments. It integrates a GNSS receiver, an inertial sensor, and an antenna in a single ultra-robust module. This receiver can simultaneously receive signals from GPS, GLONASS, BeiDou, Galileo, QZSS, and SBAS constellations using 544 built-in hardware channels and provides centimeter-level positioning services for excellent performance in multiple heading, pitch, and roll angles. It also adds an auxiliary antenna that enables heading measurement without the need for movement. This GNSS receiver offers orientation and dead reckoning, making it ideal for systems that require positioning under any channel conditions. It requires a DC supply from 9 to 48 V and consumes 8 W of power.
The AntaRx-Si3 uses AIM+ unique mitigation and monitoring system to prevent narrow and wideband interference from degrading the performance of the spectrum analyzer during the testing phase and IONO+ to ensure positioning accuracy even under periods of elevated ionospheric activity. It utilizes LOCK+ technology to maintain accurate tracking under heavy mechanical vibration. This receiver has a cold-start time of less than 45 s, a warm-start time of up to 20 s, and a re-acquisition time of 1 s. It has a velocity (INS) of 0.05 m/s (non-RTK mode) and 0.02 m/s (RTK mode). This GNSS receiver has a tracking sensitivity of 20 dB-Hz and an acquisition sensitivity of 33 dB-Hz.
This WEEE-compliant receiver is equipped with a rich set of interfaces such as Ethernet, CAN, high-speed USB, 2 event markers, and xPPS output for high-speed control and monitoring. It is available in an IP6K9K-rated housing that measures 158 x 166 x 83 mm with TNC (female) connectors.
