AsteRx SB3 CLAS – Advanced GNSS Receiver with Integrated CLAS Corrections

The AsteRx SB3 CLAS is Septentrio’s most advanced housed, multi-frequency GNSS receiver, combining cutting-edge positioning performance with outstanding reliability. Designed for use as either a rover or base station, it delivers centimetre-level RTK accuracy and sub-degree heading in a robust, IP68-rated weatherproof enclosure built to withstand the toughest environments.

Powered by triple-band, all-in-view GNSS tracking, the AsteRx SB3 CLAS ensures precise, stable positioning even in challenging conditions. It offers high update rates and low latency, making it ideal for fast-moving vehicles and dynamic machine control applications. Integrated with Japan’s Centimetre Level Augmentation Service (CLAS) via the Quasi-Zenith Satellite System (QZSS), it provides plug-and-play sub-decimetre accuracy without the need for external correction links.

Equipped with Septentrio’s renowned GNSS+ Algorithm Suite, including LOCK+, IONO+, APME+, RAIM+, and AIM+, the AsteRx SB3 CLAS delivers exceptional resilience against signal degradation caused by vibration, interference, or multipath reflections. The receiver also features an intuitive Web User Interface (WebUI) for easy configuration, monitoring, and control from any connected device.
