Home Download GNSS Receivers GNSS OEM Boards AsteRx-m3 CLAS…
AsteRx-m3 CLAS is Septentrio’s best-in-class versatile OEM board. It is a multi-frequency GNSS receiver featuring top positioning performance with flexibility to be used either as a base station or as a rover receiver. In dual antenna mode10 it provides heading & pitch or heading & roll information on top of reliable and accurate positioning. It offers the convenience of plug-and-play sub-decimeter accuracy, thanks to the integrated PPP-RTK correction service from Centimeter Level Augmentation Service (CLAS) of Japan’s Quasi-Zenith Satellite System (QZSS).
KEY FEATURES
*Flexibility of use and easy-to-integrate
*Best-in-class SWaP (Size, Weight and Power)
*Full-constellation, triple-frequency satellite tracking
*Sub-degree GNSS heading & pitch or heading & roll10
*OSNMA Support
*High update rate with low latency
*Japan Centimeter Level Augmentation Service (CLAS) integrated
Easy-to-integrate
The AsteRx-m3 CLAS comes with fully documented interfaces, commands and data messages. The included RxTools software allows receiver configuration and monitoring as well as data logging and analysis. An SDK is provided, which allows integrators to create professional custom post-processing applications.
BENEFITS
Top performance in challenging environments
The AsteRx-m3 CLAS is designed to deliver reliable and robust positions even in challenging environments. The GNSS+ toolset is the technology that allows AsteRx-m3 CLAS to be reliable also in challenging environments where the GNSS signal is disturbed or the receiver is subject to shocks and vibrations:
*AIM+ most advanced on-board anti-jamming and anti-spoofing technology in the market
*LOCK+ for robust tracking during high vibrations and shocks
*APME+ to disentangle direct signal and those reflected from nearby structures
*IONO+ provides advanced protection against ionospheric disturbance
State of the art with flexibility of use
The AsteRx-m3 CLAS is a state-of-the-art GNSS receiver using triple frequency and multi-constellation GNSS technology both for maximal positioning availability and reliability in challenging conditions. It can be used as a base station or a rover receiver in single or dial antenna configuration. In dual antenna mode10 GNSS heading provides unmatched performance in both static and dynamic conditions removing the reliance on vehicle dynamics or magnetic sensors.
Such a versatile receiver allows integrators to keep a single item in stock which can be used in a multitude of applications.
Ultra-low power design
The AsteRx-m3 CLAS provides RTK positioning at the lowest power consumption of any comparable device on the market. This means longer operation on a single battery charge, smaller batteries and greater usability.
