Septentrio AntaRx-Si3 GNSS/INS smart antenna

Thursday, 08 February, 2024 | Supplied by: Septentrio

Septentrio’s AntaRx-Si3 is a GNSS/INS (inertial navigation system) smart antenna in an ultra-rugged enclosure, designed for easy installation on machines such as agriculture robots. It leverages FUSE+ technology, 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+ is designed to improve positioning integrity, which is critical for autonomous systems.

Robust inside and out, the device is designed to be mounted outside on a machine for operation in harsh environments out in the field. It is enclosed in an impact-resistant polycarbonate IP69K housing that can handle high levels of shocks and vibrations.

The multi-frequency receiver delivers Septentrio’s RTK positioning down to the centimetre level. This can be installed with minimal effort, which is beneficial for after-market upgrades, or easily removed at the end of the day to protect against theft or vandalism. There is also a built-in 4G cell modem, so there is no need for additional modem integration.

The device 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.
