Septentrio Introduces AntaRx-Si3 Inertial GNSS Smart Antenna

Septentrio, a provider of high-precision GNSS/INS positioning solutions, has announced AntaRx-Si3. This is the first GNSS/INS (inertial navigation system) Smart Antenna on the market in an ultra-rugged enclosure, designed for easy installation on machines such as agriculture robots. AntaRx-Si3 is the new member of the family of receivers leveraging FUSE+, which is designed to answer the need for position availability in tough industrial environments where GNSS signal reception may be temporarily compromised, such as under foliage. The IMU sensor in FUSE+ also improves positioning integrity and reliability, which is critical for autonomous systems.

The AntaRx-Si3 smart antenna is robust inside and out. It is designed to be mounted outside on a machine for operation in harsh environments out in the field. Enclosed in an impact resistant polycarbonate IP69K housing it can handle high levels of shocks and vibrations. This multifrequency receiver delivers high-accuracy RTK positioning down to the centimeter level. AntaRx-Si3 has a built-in 4G cell modem, so there is no need for additional modem integration to acquire high-accuracy corrections.

AntaRx-Si3 leverages Septentrio’s GNSS+ algorithms with advanced multipath mitigation, which allows uninterrupted operation in environments where satellite signals could be reflected off nearby machinery or high structures such as silos. It delivers positioning at a high update rate and low latency, which are critical for control loops in autonomous movement or rotation.
